Hello, Im trying to start some developing for the android, I am hampered by my inability to get the emulator to work, im sure im overlooking something basic, here is the error that generated.
invalid command-line parameter: Files\Android\android-sdk\tools/emulator-arm.exe.
Hint: use 'foo' to launch a virtual device named 'foo'.
please use -help for more information
can someone help please relieve a noob of my frustration.
I have the same problem :/
Any help please?
Android AVD emulator connect problem
Similar to the previous two post, I also am unable to display my Helloworld App onto the AVD emulator skin.
The code is the traditional helloworld code:
package com.muo.helloworld;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloWord extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello Honeycomb Droid");
setContentView(R.layout.main);
}
}
The Eclipse Console runtime error is as follows:

Hello,
I tried to use following code on my QTEK 8300: http://developer.sonyericsson.com/s...kscode/java/p_midlets_hge100_gpsaccessory.jsp
but I got: javax.microedition.io.ConnectionNotFoundException when opening the serial port: commConn = (CommConnection) Connector.open("comm:COM6;baudrate=115000");
COM6 is the serial port for bluetooth access. The number is found in bluetooth setting menu
The same bluetooth setting works with TomTom
The midlet security is set Always Allow for Local connection
The midlet manager is: Esmertec Jbed MIDP 2.0 Build ID: 20070802.2.1
OS: Windows Mobile 6 5.2.318 (from http://www.coolcode.cn/archives/?article-282.html)
My goal is:
- programming with midlet
- dialog with GPS via serial port (virtual or physical port)
Could you please tell me what is wrong ?
Thanks
hi
I think, Jbed is a kind of generic midlet manager, not Designed for your phone, So it can't acess to the serial port. I have allready tryed to comunicat with the IR port (based on serial port) without success
Serial port access in midlet on my pocket pc (Artemis) tests:
Esmertec 20071119.3.1 build - no go
Intent MIDlet Manager - no go
Only good old IBM J9 (WEME) 6.1.1 works... ;-)
Thanks for your help
I found also the why of the problem already explained by jockyw2001 and Menneisyys: http://forum.xda-developers.com/showthread.php?t=339579&page=2
I would like to have Smartphone IBM J9 6.1.1 if someone has it. Thanks
Hello,
I'm just unable to make my midlet work even with IBM J9 6.1.1. I got a blank screen (process seems blocked) with following code:
import java.io.IOException;
import javax.microedition.midlet.*;
import javax.microedition.io.CommConnection;
import javax.microedition.io.Connector;
import javax.microedition.lcdui.*;

public class GpsEnabler extends MIDlet implements CommandListener {
private Command exitCommand;
private TextBox tbox;
private CommConnection commConn = null;
public GpsEnabler() {
exitCommand = new Command("Exit", Command.EXIT, 1);
try {
commConn = (CommConnection) Connector.open("comm:COM6;baudrate=115000");
tbox = new TextBox("Hello world MIDlet", "Hello World! OK", 60, 0);
} catch (IOException e) {
tbox = new TextBox("Hello world MIDlet", "Hello World! Not OK", 60, 0);
}
tbox.addCommand(exitCommand);
tbox.setCommandListener(this);
}
public void startApp() {
Display.getDisplay(this).setCurrent(tbox);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
public void commandAction(Command cmd, Displayable disp) {
if (cmd == exitCommand) {
destroyApp(false);
notifyDestroyed();
}
}
}
What's wrong or missing again ?
Thanks
The example: http://forum.java.sun.com/thread.jspa?threadID=5254716&tstart=105 works with an available serial port (COM4 with my QTEK 8300 with TomTom installed, got with System.getProperty("microedition.commports")
At this time, my courseload is way too high for me to do this. I also formatted and lost my sourcecode so I would have to write it from scratch. Sorry!
http://www.4shared.com/file/103246844/247a67c/WPA_Enterprise.html
Look below for instructions to request your school
Root, of course, is required.
The only other things this program needs is for the user to input their username and password as well as copy the security certificate to their SDcard as well as copying the security file to the SDcard. The program takes care of the rest.
I can modify my program to allow other people to connect to WPA Enterprise places in their area. If there is interest in this, let me know and I would be happy to upload versions of my program that allows others to connect.
Donations are always enjoyed
For UT Students:
1. Copy cacerts.pem to your SDCard. Make sure its named cacerts.pem NOT cacerts.pem or anything else similar. The program is CASE SENSITIVE. Make sure to UNMOUNT your sdcard from the computer
2. Run the program and click always to the superuser prompt (if you have it installed)
3. Input your information.
4. Click Save
5. Click Install
6. Click Reboot
If you ever need to revert, just open the program and click undo!
For UNSW Students:
1. Run the program and click always to the superuser prompt (if you have it installed)
3. Input your password (leave username blank)
4. Click Save
5. Click Install
6. Click Reboot
If you ever need to revert, just open the program and click undo!
For Georgia Tech Students
1. Copy Equifax_Secure_CA.pem to your SDCard. Make sure its named Equifax_Secure_CA.pem. The program is CASE SENSITIVE. Make sure to UNMOUNT your sdcard from the computer
2. Run the program and click always to the superuser prompt (if you have it installed)
3. Input your information.
4. Click Save
5. Click Install
6. Click Reboot
If you ever need to revert, just open the program and click undo!
If anyone else wants it, link me to a page like this one and it will give me an example config.
Enjoy!

Sounds good, can finally connect to wifi @ my university
Program Released!
need a config pls
thanks alot for this.
here's a link for my uni : http://www.port.ac.uk/special/is/mobilemedia/broadband/wirelessoncampus/ -> its got the config details.
my uni operates on both wpa/wpa2 and the auth is peap, mschapv2
the cer certificate is on the windows xp part on the above link.
ive converted my .cer to .pem through openssl, so atleast one step is complete.

We've got the same settings here for WPA-Enterprise, only the SSID is "OpenWLAN". (WPA-TKIP / WPA2-AES (Enterprise) & EAP (PEAP and MS-CHAPv2))
Do you think there is a way to do this?
Please post the source. I suggest that other UT students refrain from using this application until then, due to the ridiculously high abuse potential of an app that elevates to root, and even worse, one that you enter EID + password in.
The normal restrictions on network access can be sidestepped. Your EID and password could easily be harvested. Don't run apps like this until the source is available and someone reputable looks at it.
I posted UT Austin specific instructions back in November. If you want access at UT but don't like to gamble, feel free to give them a try. They're a bit dated with respect to gaining root.
http://forum.xda-developers.com/showthread.php?t=450915
I'll add also that the instructions will probably work at any location using WPA Enterprise auth - anything that wpa_supplicant supports. There are several examples in my thread of people getting it to work at their school/workplace. You can either create the configuration file yourself by looking at the Windows/Mac/whatever instructions made available to you, or you may try contacting the local IT dept.

Here is my source. There is an XML portion that takes care of the interface.
To be truthful, I'm kind of embarrassed of the code because I haven't touched Java since highschool. There is nothing wrong with this application, and nothing nefarious. To be honest, I wouldn't know how to do something like that if I wanted since I would have to delve into the commands.
If you have any suggestions for my code, I would be happy to hear them.
I took up this application as a side product just to see if my knowledge of linux was strong enough (I used linux on my netbook for a while before switching to windows 7) and once I got it working I wanted to share it with the community that has given me so much on both my current phone and previous ones.
Anyway, to all the people in this thread who are requesting stuff:
My birthday is today and my girlfriend came up to UT to celebrate with me. She won't be leaving until Sunday so.... I won't be working on it until Sunday. Bear with me though, I will get it up for you guys if I can (again, I pretty much suck. But now that the framework is down, I think I know what to do)
Smurfette, I took a look there and I'm pretty sure I can do it for you
Georgia Institute of Technology Pilot WPA Program
http://www.lawn.gatech.edu/help/gtwpa/
These are the instructions about signing on to WPA at my university. I will look at modifying the source myself, but I don't have time either at the moment. Just curious--how many other GT students are using XDA-developers to mod their Dream??
So far I am sure I can do it for ellingthepirate and smurphete. I found example configurations for those two. I'm not sure about N23 or the guy on the other page yet. Again, I won't be able to update the app until sunday night (central time) at the earliest.
Will this eventually work with the *.cer certificates?
Hi Persiansown,
I am working on something similar. Can you tell me how did you get permission to create/modify wpa_supplicant.conf programatically?
THANK YOU SO MUCH!!

Never mind! I've figured it out!
Updated for University of South Wales and Georgia Tech
Hello,
I am trying to use KillingInTheNameOf (on a compatible device) to write the
service.adb.tcp.port 5555
property. Then I try to restart adbd by killing it such that it will bind to 5555.
Then, my aim is to connect to this from code running on the device itself.
1. Is this possible?
2. I manage to write the property (I know this by listing the contents of the memory area in KillingInTheNameOf itself), but getprop returns blank.
http://pastebin.com/uC9HQYe6
-Earlence
updates
update. I managed to insert the new property at the end of the list. nothing crashes. iterating thru the shared mem, lists the new property at the end, but getprop returns a blank.
This is the relevant parts of the code
void create_new_prop(char *name, char *value, struct prop_area *pa, struct prop_info *pi)
{
int namelen = strlen(name);
int valuelen = strlen(value);
int pa_count = pa->count;
while(pa_count--)
++pi;
printf("pi addr: %x\n", pi);
memcpy(pi->name, name, namelen + 1);
memcpy(pi->value, value, valuelen + 1);
pa->toc[pa->count] = (namelen << 24) | (((unsigned) pi) - ((unsigned) pa));
pa->count++;
}
-Earlence
more updates
IT seems that property_change has to be fired for any property to "take effect". (no wonder the KillingInTheNameOf exploit kills adb and restarts it).
Anyone have ideas on how to trick an execution of "property_change" ?

Hi Experts / Expert Hackers,
I'm trying to implement the Google Play application silent install feature (similar to appbrain fast web installer) on android.
So far I was able achieve the following :
1. Find out a method to retrieve the Google Play Auth Token (thus granting permission for my application to talk with Google Play application on the Phone). I've listed the code I've used for this below :
Code:
Log.i(TAG,"Getting the Google Play Auth Token Using Account Manager : START");
AccountManager accountManager = AccountManager.get(getApplicationContext());
Account[] accArr = accountManager.getAccountsByType("com.google");
for (Account acc : accArr) {
Log.i(TAG, "For Account Name : " + acc.name + " - "+ "Account Type : " + acc.type);
accountManager.getAuthToken(acc, "googleplay", null, this,new AccountManagerCallback<Bundle>() {
public void run(
AccountManagerFuture<Bundle> paramAccountManagerFuture) {
try {
Bundle localBundle = (Bundle) paramAccountManagerFuture.getResult();
String authToken = localBundle.get("authtoken") + "";
Log.i(TAG, "Got AuthToken : " + authToken);
} catch (Exception ex) {
StackTraceElement[] starray = ex.getStackTrace();
StringBuffer bf = new StringBuffer();
bf.append("Error : " + ex.getMessage()).append("\n");
for (StackTraceElement ste : starray) {
bf.append(ste.toString()).append("\n");
}
Log.e(TAG, bf.toString());
}
}
}, null);
}
Log.i(TAG,"Getting the Google Play Auth Token Using Account Manager : END");
2. Find out how to Retrieve the Android-Id of the Phone (This Id as I believe should be used when sending the appInstall request to the GPlay Servers or the Gplay/vending application on the android phone)
Code:
Log.i(TAG, "Getting the Android ID Of the Phone : START");
Uri localUri = Uri.parse("content://com.google.android.gsf.gservices");
ContentResolver localContentResolver = getContentResolver();
String[] arrayOfString = new String[1];
arrayOfString[0] = "android_id";
Cursor localCursor = localContentResolver.query(localUri, null,null, arrayOfString, null);
Log.i(TAG, "Column Count : " + localCursor.getColumnCount());
if ((localCursor != null) && (localCursor.moveToFirst())) {
String androidId = Long.toHexString(Long.parseLong(localCursor.getString(1)));
Log.i(TAG, "Received Android ID : " + androidId);
Log.i(TAG,"Other Value in Column : " + localCursor.getString(0));
}
Log.i(TAG,"Getting the Android ID of the Phone : END");
3. Find out the Protocol Buffer Request to be sent to the Google Play servers or the Gplay/vending application on the phone to Initiate the silent application download & install process.
Code:
message InstallRequest {
optional string appId = 1;
}
message RequestContext {
required string authSubToken = 1;
required bool isSecure = 2;
required int32 version = 3;
required string androidId = 4;
optional string deviceAndSdkVersion = 5;
optional string userLanguage = 6;
optional string userCountry = 7;
optional string operatorAlpha = 8;
optional string simOperatorAlpha = 9;
optional string operatorNumeric = 10;
optional string simOperatorNumeric = 11;
}
message Request {
optional RequestContext context = 1;
repeated group RequestGroup = 2 {
optional InstallRequest installRequest = 10;
}
}
4.I even used the protobuf compiler and generated the java class for manipulating the above protocol buffer request and filled the above protocol buffer fields with some sample data. See the code below :
Code:
public void buildAndSendSilentInstallProtoBuffMessage(String gplayAuthToken, String deviceAndroidId){
try{
/*
* The Root Request Object Assumed to be Holding the Silent Install Request
*/
Request.Builder request = Request.newBuilder();
//Populating the ReequestContext Object
RequestContext.Builder context = RequestContext.newBuilder();
context.setAndroidId(deviceAndroidId);
context.setAuthSubToken(gplayAuthToken);
context.setIsSecure(true);
context.setVersion(1002);
context.setDeviceAndSdkVersion("dream:4");
context.setUserLanguage("en");
context.setUserCountry("us");
context.setOperatorAlpha("Android");
context.setOperatorNumeric("310260");
context.setSimOperatorNumeric("310260");
//Building the Install Request
InstallRequest.Builder installRequest = InstallRequest.newBuilder();
installRequest.setAppId("-2564446724934482383");
//Setting the Install Request to the Request Group
RequestGroup.Builder requestGroup = RequestGroup.newBuilder();
requestGroup.setInstallRequest(installRequest);
//Setting the Request Context to the Main Request Object
request.setContext(context);
//Setting the Request Group to the Request Object
request.addRequestGroup(requestGroup);
The Sample Data for GPlay Token and the Android Id are as follows :
1. Android_ID :
3a0f901831a0f402
2. Google Play AuthToken :
DQAAAMgAAACpOyPf6apRbb0i4qhTVaf0yYoikTAb4TYlHCRLrW4mu5f14j-H35KGmO9TQKUDYCfj3-b-QIH5chfXT3bS02Uxljg7vYt4I-kgXLEJwPcynjugDcJ9fYPOh1c2FnOnywFXXxXw6hcqs5sVnJEt5zW2ditoB5VeeXG9Zfodj9dXKobObi50-XnHoGfWi2b64Uf3EHGdQTsDCMzfZrE4mb22fr9LCW1oZG5tkzwS4KhPBHWMN2fO7w-1IZ4UK5LOI80vPBLjxBaavKAXHoVUHSNV
5. I also did some sniffing using my rooted galaxy nexus phone during Gplay application silent install and found only two HTTP GET Requests.
I tried reproducing the those two Http GET requests captured using Shark for root(using my rooted android galaxy nexus phone) and the 1st Request just downloads the Market File itself (which I was able to save to the SD card of the Phone. But then it has to be installed like any unknown sources application) while the second request returns nothing.
The two get requests captured are shown below :
Code:
1. GET REQUEST ONE :

I've been looking into this for about two weeks now but I still couldn't find the following :
1. Whether the AppBrain fast Web Installer uses the protocol buffer to invoke the Gplay (vending application) on the phone or the Gplay servers ?. If so is the above Protocol Buffer Request format correct ??.
2. If the Above Protocol Buffer Request format is correct then to Where in the Phone or Gplay server should I send the Protocol buffer request to to invoke the Silent Application download and installing procedure ?.
I also have a C2DM (now GCM) server and client setup around this task as well. Could anyone point me in the correct direction or give me any clues for solving this ?. Any help is much appreciated .
Seriously No one ???. I thought this forum has some expert hackers . Where are those so called android hackers anyways ??. Please guys I need help on this and it's urgent .
Hello. How you login into google play with token from account manager? Thanks.

In this article I’ve described:
• How to develop simple Java service for the Android Devices;
• How to communicate with a service from the other processes and a remote PC;
• How to install and start the service remotely from the PC.
1. Java Service Development for the Android Devices
Services are long running background processes provided by Android. They could be used for background tasks execution. Tasks can be different: background calculations, backup procedures, internet communications, etc. Services can be started on the system requests and they can communicate with other processes using the Android IPC channels technology. The Android system can control the service lifecycle depending on the client requests, memory and CPU usage. Note that the service has lower priority than any process which is visible for the user.
Let’s develop the simple example service. It will show scheduled and requested notifications to user. Service should be managed using the service request, communicated from the simple Android Activity and from the PC.
First we need to install and prepare environment:
• Download and install latest Android SDK from the official web site http://developer.android.com);
• Download and install Eclipse IDE (http://www.eclipse.org/downloads/);
• Also we’ll need to install Android Development Tools (ADT) plug-in for Eclipse.
After the environment is prepared we can create Eclipse Android project. It will include sources, resources, generated files and the Android manifest.
1.1 Service class development
First of all we need to implement service class. It should be inherited from the android.app.Service (http://developer.android.com/reference/android/app/Service.html) base class. Each service class must have the corresponding <service> declaration in its package's manifest. Manifest declaration will be described later. Services, like the other application objects, run in the main thread of their hosting process. If you need to do some intensive work, you should do it in another thread.
In the service class we should implement abstract method onBind. Also we override some other methods:
onCreate(). It is called by the system when the service is created at the first time. Usually this method is used to initialize service resources. In our case the binder, task and timer objects are created. Also notification is send to the user and to the system log:
Code:
01.public void onCreate()
02.{
03. super.onCreate();
04. Log.d(LOG_TAG, "Creating service");
05. showNotification("Creating NotifyService");
06.
07. binder = new NotifyServiceBinder(handler, notificator);
08. task = new NotifyTask(handler, notificator);
09. timer = new Timer();
10.}
onStart(Intent intent, int startId). It is called by the system every time a client explicitly starts the service by calling startService(Intent), providing the arguments it requires and the unique integer token representing the start request. We can launch background threads, schedule tasks and perform other startup operations.
Code:
1.public void onStart(Intent intent, int startId)
2.{
3. super.onStart(intent, startId);
4. Log.d(LOG_TAG, "Starting service");
5. showNotification("Starting NotifyService");
6.
7. timer.scheduleAtFixedRate(task, Calendar.getInstance().getTime(), 30000);
8.}
onDestroy(). It is called by the system to notify a Service that it is no longer used and is being removed. Here we should perform all operations before service is stopped. In our case we will stop all scheduled timer tasks.
Code:
1.public void onDestroy()
2.{
3. super.onDestroy();
4. Log.d(LOG_TAG, "Stopping service");
5. showNotification("Stopping NotifyService");
6.
7. timer.cancel();
8.}
onBind(Intent intent). It will return the communication channel to the service. IBinder is the special base interface for a remotable object, the core part of a lightweight remote procedure call mechanism. This mechanism is designed for the high performance of in-process and cross-process calls. This interface describes the abstract protocol for interacting with a remotable object. The IBinder implementation will be described below.
Code:
1.public IBinder onBind(Intent intent)
2.{
3. Log.d(LOG_TAG, "Binding service");
4. return binder;
5.}
To send system log output we can use static methods of the android.util.Log class (http://developer.android.com/reference/android/util/Log.html). To browse system logs on PC you can use ADB utility command: adb logcat.
The notification feature is implemented in our service as the special runnable object. It could be used from the other threads and processes. The service class has method showNotification, which can display message to user using the Toast.makeText call. The runnable object also uses it:
Code:
01.public class NotificationRunnable implements Runnable
02.{
03. private String message = null;
04.
05. public void run()
06. {
07. if (null != message)
08. {
09. showNotification(message);
10. }
11. }
12.
13. public void setMessage(String message)
14. {
15. this.message = message;
16. }
17.}
Code will be executed in the service thread. To execute runnable method we can use the special object android.os.Handler. There are two main uses for the Handler: to schedule messages and runnables to be executed as some point in the future; and to place an action to be performed on a different thread than your own. Each Handler instance is associated with a single thread and that thread's message queue. To show notification we should set message and call post() method of the Handler’s object.
1.2 IPC Service
Each application runs in its own process. Sometimes you need to pass objects between processes and call some service methods. These operations can be performed using IPC. On the Android platform, one process can not normally access the memory of another process. So they have to decompose their objects into primitives that can be understood by the operating system , and "marshall" the object across that boundary for developer.
The AIDL IPC mechanism is used in Android devices. It is interface-based, similar to COM or Corba, but is lighter . It uses a proxy class to pass values between the client and the implementation.
AIDL (Android Interface Definition Language) is an IDL language used to generate code that enables two processes on an Android-powered device to communicate using IPC. If you have the code in one process (for example, in Activity) that needs to call methods of the object in another process (for example, Service), you can use AIDL to generate code to marshall the parameters.
Service interface example showed below supports only one sendNotification call:
Code:
1.interface INotifyService
2.{
3.void sendNotification(String message);
4.}
The IBinder interface for a remotable object is used by clients to perform IPC. Client can communicate with the service by calling Context’s bindService(). The IBinder implementation could be retrieved from the onBind method. The INotifyService interface implementation is based on the android.os.Binder class (http://developer.android.com/reference/android/os/Binder.html):
Code:
01.public class NotifyServiceBinder extends Binder implements INotifyService
02.{
03. private Handler handler = null;
04. private NotificationRunnable notificator = null;
05.
06. public NotifyServiceBinder(Handler handler, NotificationRunnable notificator)
07. {
08. this.handler = handler;
09. this.notificator = notificator;
10. }
11.
12. public void sendNotification(String message)
13. {
14. if (null != notificator)
15. {
16. notificator.setMessage(message);
17. handler.post(notificator);
18. }
19. }
20.
21. public IBinder asBinder()
22. {
23. return this;
24. }
25.}
As it was described above, the notifications could be send using the Handler object’s post() method call. The NotificaionRunnable object is passed as the method’s parameter.
On the client side we can request IBinder object and work with it as with the INotifyService interface. To connect to the service the android.content.ServiceConnection interface implementation can be used. Two methods should be defined: onServiceConnected, onServiceDisconnected:
Code:
01.ServiceConnection conn = null;
02.…
03.conn = new ServiceConnection()
04.{
05. public void onServiceConnected(ComponentName name, IBinder service)
06. {
07. Log.d("NotifyTest", "onServiceConnected");
08. INotifyService s = (INotifyService) service;
09. try
10. {
11. s.sendNotification("Hello");
12. }
13. catch (RemoteException ex)
14. {
15. Log.d("NotifyTest", "Cannot send notification", ex);
16. }
17. }
18.
19. public void onServiceDisconnected(ComponentName name)
20. {
21. }
22.};
The bindService method can be called from the client Activity context to connect to the service:
1. Context.bindService(new Intent(this, NotifyService.class),
2.conn, Context.BIND_AUTO_CREATE);
The unbindService method can be called from the client Activity context to disconnect from the service:
1.Context.unbindService(conn);
1.3 Remote service control
Broadcasts are the way applications and system components can communicate. Also we can use broadcasts to control service from the PC. The messages are sent as Intents, and the system handles dispatching them, including starting receivers.
Intents can be broadcasted to BroadcastReceivers, allowing messaging between applications. By registering a BroadcastReceiver in application’s AndroidManifest.xml (using <receiver> tag) you can have your application’s receiver class started and called whenever someone sends you a broadcast. Activity Manager uses the IntentFilters, applications register to figure out which program should be used for a given broadcast.
Let’s develop the receiver that will start and stop notify service on request. The base class android.content.BroadcastReceiver should be used for these purposes (http://developer.android.com/reference/android/content/BroadcastReceiver.html):
Code:
01.public class ServiceBroadcastReceiver extends BroadcastReceiver
02.{
03.…
04. private static String START_ACTION = "NotifyServiceStart";
05. private static String STOP_ACTION = "NotifyServiceStop";
06.…
07. public void onReceive(Context context, Intent intent)
08. {
09. …
10. String action = intent.getAction();
11. if (START_ACTION.equalsIgnoreCase(action))
12. {
13. context.startService(new Intent(context, NotifyService.class));
14. }
15. else if (STOP_ACTION.equalsIgnoreCase(action))
16. {
17. context.stopService(new Intent(context, NotifyService.class));
18. }
19.
20. }
21.}
To send broadcast from the client application we use the Context.sendBroadcast call. I will describe how to use receiver and send broadcasts from the PC in chapter 2.
1.4 Android Manifest
Every application must have an AndroidManifest.xml file in its root directory. The manifest contains essential information about the application to the Android system, the system must have this information before it can run any of the application's code. The core components of an application (its activities, services, and broadcast receivers) are activated by intents. An intent is a bundle of information (an Intent object) describing a desired action — including the data to be acted upon, the category of component that should perform the action, and other pertinent instructions. Android locates an appropriate component to respond to the intent, starts the new instance of the component if one is needed, and passes it to the Intent object.
We should describe 2 components for our service:
• NotifyService class is described in the <service> tag. It will not start on intent. So the intent filtering is not needed.
• ServiceBroadcastReceived class is described in the <receiver> tag. For the broadcast receiver the intent filter is used to select system events:
Code:
01.<application android:icon="@drawable/icon" android:label="@string/app_name">
02.…
03. <service android:enabled="true" android:name=".NotifyService"
04.android:exported="true">
05. </service>
06. <receiver android:name="ServiceBroadcastReceiver">
07. <intent-filter>
08. <action android:name="NotifyServiceStart"></action>
09. <action android:name="NotifyServiceStop"></action>
10. </intent-filter>
11. </receiver>
12.…
2. Java service remote installation and start
2.1 Service installation
Services like the other applications for the Android platform can be installed from the special package with the .apk extension. Android package contains all required binary files and the manifest.
Before installing the service from the PC we should enable the USB Debugging option in the device Settings-Applications-Development menu and then connect device to PC via the USB.
On the PC side we will use the ADB utility which is available in the Android SDK tools directory. The ADB utility supports several optional command-line arguments that provide powerful features, such as copying files to and from the device. The shell command-line argument lets you connect to the phone itself and issue rudimentary shell commands.
We will use several commands:
• Remote shell command execution: adb shell <command> <arguments>
• File send operation: adb push <local path> <remote path>
• Package installation operation: adb install <package>.apk
I’ll describe the package installation process in details. It consists of several steps which are performed by the ADB utility install command:
• First of all the .apk package file should be copied to the device. The ADB utility connects to the device and has limited “shell” user privileges. So almost all file system directories are write-protected for it. The /data/local/tmp directory is used as the temporary storage for package files. To copy package to the device use the command:
adb push NotifyService.apk /data/local/tmp
• Package installation. ADB utility uses special shell command to perform this operation. The “pm” (Package Manager?) utility is present on the Android devices. It supports several command line parameters which are described in the Appendix I. To install the package by yourself execute the remote shell command:
adb shell pm install /data/local/tmp/NotifyService.apk
• Cleanup. After the package is installed, ADB removes the temporary file stored in /data/local/tmp folder using the “rm” utility:
adb shell rm /data/local/tmp/NotifyService.apk.
• To uninstall package use the “pm” utility:
adb shell pm uninstall <package>
2.2 Remote service control
To be able to start and stop the NotifyService from the PC we can use the “am” (Activity Manager?) utility which is present on the Android device. The command line parameters are described in the Appendix II. The “am” utility can send system broadcast intents. Our service has the broadcast receiver which will be launched by the system request.
To start NotifyService we can execute remote shell command:
adb shell am broadcast –a NotifyServiceStart
To stop the NotifyService we can execute remote shell command:
adb shell am broadcast –a NotifyServiceStop
Note, that the NotifyServiceStart and NotifyServiceStop intents were described in the manifest file inside the <receiver> … <intent-filter> tag. Other requests will not start the receiver.
Appendix I. PM Usage (from Android console)
Code:
01.pm [list|path|install|uninstall]
02.pm list packages [-f]
03.pm list permission-groups
04.pm list permissions [-g] [-f] [-d] [-u] [GROUP]
05.pm path PACKAGE
06.pm install [-l] [-r] PATH
07.pm uninstall [-k] PACKAGE
08.
09.The list packages command prints all packages.
10.Use the -f option to see their associated file.
11.The list permission-groups command prints all known permission groups.
12.The list permissions command prints all known permissions, optionally
13.only those in GROUP.
14.
15.Use the -g option to organize by group.
16.Use the -f option to print all information.
17.Use the -s option for a short summary.
18.Use the -d option to only list dangerous permissions.
19.Use the -u option to list only the permissions users will see.
20.
21.The path command prints the path to the .apk of a package.
22.
23.The install command installs a package to the system. Use the -l option to
24. install the package with FORWARD_LOCK. Use the -r option to reinstall an
25.exisiting app, keeping its data.
26.The uninstall command removes a package from the system. Use the -k option
27.to keep the data and cache directories around after the package removal.
Appendix II. AM Usage (from Android console)
Code:
01.am [start|broadcast|instrument]
02.am start -D INTENT
03.am broadcast INTENT
04.am instrument [-r] [-e <ARG_NAME> <ARG_VALUE>] [-p <PROF_FILE>] [-w] <COMPONENT>
05.
06.INTENT is described with:
07. [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
08. [-c <CATEGORY> [-c <CATEGORY>] ...]
09. [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
10. [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
11. [-e|--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
12. [-n <COMPONENT>] [-f <FLAGS>] [<URI>]
13.
