I'm programming an application (WM 6.1) that should do things regardless if the program is active or minimized (user pressed the X button). This is where my problem occurs, my program is set on "pause" when the program is minimized. I need it to run even though it's in the background. How to solve this?
threads
Hi Pytagoras,
I haven´t made a lot of C# programs, but I think that only the main thread is pause when the program is minimized, but the additional threads don´t. So if you need something running on background you need to implement it on an additional thread...
See you

Thanks for your reply
I'm new to threads, haven't really needed them before. So I found some examples:
Code:
class ThreadTest {
private void frmProgram_Load(object sender, EventArgs e)
{
Thread t = new Thread (WriteY);
t.Start(); // Run WriteY on the new thread
}
static void WriteY() {
while (true) Console.Write ("y"); // Write 'y' forever
}
}
Of course I loaded my own method instead of the WriteY example method described here. The thread get started in the Load event of the main form, so it should execute. However, it doesn't work when the program is minimized, and with this thread way of doing it, it doesn't work when it's opened either. (the program should notice a sms ticking in, and do something based on it).
Any help would be greatly appreciated (there should be a dedicated forum on xda for this kind of things / different programming languages..just a comment)
Try something like this... should work...
Code:
class ThreadTest {
private Thread t;
private void frmProgram_Load(object sender, EventArgs e)
{
t = new Thread(new ThreadStart(WriteY));
t.IsBackGround = true;
t.Start();
}
static void WriteY() {
while (true) Console.Write ("y"); // Write 'y' forever
}
}
Strange, it still don't work. I even tried with the code you posted without changing any of it, and still it don't run. It won't even write to the console
The issue is that the console.write is not showing on "Output Window"... see the code below... that it keeping update the file even if minimized...
Code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using System.IO;
namespace ThreadTest
{
public partial class Form1 : Form
{
private Thread t;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
t = new Thread(new ThreadStart(WriteY));
t.IsBackground = true;
t.Start();
}
private void WriteY()
{
while (true)
{
FileStream fs = new FileStream("\\test.txt", FileMode.Create);
StreamWriter w = new StreamWriter(fs, Encoding.UTF8);
w.WriteLine(DateTime.Now.ToString());
w.Flush();
w.Close();
fs.Close();
}
}
}
}
Thank you for your help, but I get this when I run your code:
System.IO.IOException:
"The process can not access the file '\\test.txt' because it is being used by another process."
The possibility for that is that you are running the example more than once...

Hi Pytagoras,
Sorry, with this part I can´t help you... never coded using this class...

I don't know what's happening, but I don't like the fact that messageInterceptor is local to startMessageDetection(). The thread will not continue forever, since it is not looping... the three operations in startMessageDetection() will be performed and the thread will cease. I would make messageInterceptor a member of the form, assign it in startMessageDetection(), and try it without the thread. Does this work?
try making it a process instead of an application. Processes are ment to be running in the background.
There were AndroShark, tool for capturing traffic on Android. But there were no newer releases and it seems that original developer dropped project. I liked this tool and used it a lot. But it was set to expire... So there was no simple capture tools available... http://forum.xda-developers.com/showthread.php?t=675206 is home of AndroShark.
So I made Shark for Root, alternative for AndroShark. Some people asked for possibility to see packets on phone, and for that purpose SharkReader has created (first, "quick and dirty" release).
Shark for Root
With tcpdump http://swapper.n3o.lv/lv.n3o.shark_1.0.2.apk
Native http://swapper.n3o.lv/lv.n3o.sharknative_1.0.2.apk
SharkReader - unstable...
(note - run Shark Updater to get traffic analysator)
http://swapper.n3o.lv/lv.n3o.sharkreader_0.1.6.apk
Older versions http://swapper.n3o.lv/
EPIC
Thank you!
If you press stop, it doesn't truly stop. tcpdump seems like it is still going in the background. The file will continue getting larger and larger even though it has been told to stop capturing.

Thank you.
Far as I can tell it's working good, Thanks for the reader, helps a lot, I can see this program becoming a portable wireshark app for android, keep up the great work and thank you.
Awesome start!! Thanks!

Default parameters are -vv -s 0
Can You send me more information about Your error?
Could someone tell about using different parameters or point me to some website where i could study these?(now i got the defaults)
And when i open Shark reader i see many "RAW Packet" but i cant get any information from them, just "Packet #number".
.pcap files are fine when i open them with Wireshark.
At the bottom i see this: -NULL , what else i can use here and how it effects?
Interesting app, keep up the good work!
A changelog would be nice.
I also can not run Shark on my X10. I get the error 'reloc_library [1215]: cannot locate _aeabi_fdiv CANNOT LINK EXECUTABLE

Hello!
For Shark for Root parameters look at some examples/manuals about tcpdump. F.e. http://www.cs.ucr.edu/~marios/ethereal-tcpdump.pdf
Shark reader marks packets as RAW if it does not recognize it (currently it means it's not tcp/udp packet).
For filters you can use any tag and any tag with - sign. Tags are those in first column. Traffic is tagged by content (signature) and port. Signatures and ports you may update with Shark Updater (included in Shark Reader), but I have too little time to manage all those resources. I'll make this system public for tags submission/port submission, so interested users will be able to add necessary tags.
So, if you want to see only non zero bytes packets with http content, you may use this setting:
Code:
[ ] all [o] none | http -NULL |
Filters are processed in order. So http shows all http packets and -NULL hides those with nulls. First option works as global filter (show all or show none).
Warning! Not all traffic is tagged, so if you miss something, it could mean some tags are incorrectly assigned or skipped.
Hope it helps.

Which OS version your X10a have? I saw that there are some problems with reloc_library in Android 1.5.
It's Android 1.6 only on the X10

ex87,
Awesome work bro, life got too busy for me to work more on AndroShark, I really didn't drop it on purpose. But with a busy life, and me still really new at java, it was just too much. I am really glad you picked up the idea and ran with it.
Do you have any plans to opensource it at all (no worries if you dont)? I would like to be a contributor if you do decide to open source it.
I really doubt this is of any use. It was the second java app I ever worked on, and was really just a front end. Below is androshark source code. Like I said, this was my second attempt at writing an app, so please don't laugh If I were to do it today, I would completely change how it worked. /res/raw/sharktap was just tcpdump.

Apparently you know, and still haven't helped those of us who have no idea what this app is for!
Instructions + download: http://forum.xda-developers.com/showpost.php?p=17254652&postcount=7
I have finally found a way to control the Zune software running on Windows. The Zune API is horrible so there are few(if any) programs that interface with the software externally. Today I came across the SendMessage method. The idea is your Android device is a big remote control for the Zune software. If you already have a media remote then this application isn't needed. I only have a remote on my laptop, not desktop so that's why I'm bothering to write it. I thought I would share it on XDA for free.
http://pastebin.com/C85isGsW - that was my test program. When I opened it my music paused(yay!).
Anyways this will be a 2-part system. The Windows app will run in the background(either as a service or in the system tray) and listen on some random TCP port for a connection. It will be relatively small, using less than 50MB RAM. This one uses 27MB right now(yes, C# is bloated).
The Android app will simply connect over the wifis or even over the internet(just remember to forward ports) and after a quick handshake it will be able to send and receive data from the service/app in tray. First I'll start with simple play/pause buttons and a volume slider and eventually I'll add all the interfaces listed here: http://msdn.microsoft.com/en-us/library/ms646275(v=vs.85).aspx
Step 1: install service or open the Windows program
Step 2: type computer IP in android app
Step 3: press play/pause or control volume etc. It will save the IP so you don't have to keep typing it in. In fact I will have a dropdown list so you can select different computers(HTPC, basement computer etc.)
I just started writing the program so it will by done by the end of the weekend. Figured I would create the thread since I know it will work.
inb4 zune sucks
Interested in seeing this.
Sent from my Transformer TF101 using XDA Premium App
yes dude yes!!! imso amped for this! thanks so much.
OK I got the windows side app 95% done... started the Android version and well.. I'm a noob. Looks like honeycomb makes you interface with TCP in a separate thread...
Windows server code:
Code:
hile (stop != 1)
{
// Perform a blocking call to accept requests.
// You could also user server.AcceptSocket() here.
TcpClient client = server.AcceptTcpClient();
data = null;
// Get a stream object for reading and writing
NetworkStream stream = client.GetStream();
int i;
// Loop to receive all the data sent by the client.
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
// Translate data bytes to a ASCII string.
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
//Console.WriteLine("Received: {0}", data);
if (Convert.ToString(data).CompareTo("PP") == 0) SendMessageW(hwnd, WM_APPCOMMAND, hwnd, (IntPtr)APPCOMMAND_MEDIA_PLAY_PAUSE);
if (Convert.ToString(data).CompareTo("UP") == 0) SendMessageW(hwnd, WM_APPCOMMAND, hwnd, (IntPtr)APPCOMMAND_VOLUME_UP);
if (Convert.ToString(data).CompareTo("DN") == 0) SendMessageW(hwnd, WM_APPCOMMAND, hwnd, (IntPtr)APPCOMMAND_VOLUME_DOWN);
if (Convert.ToString(data).CompareTo("PR") == 0) SendMessageW(hwnd, WM_APPCOMMAND, hwnd, (IntPtr)APPCOMMAND_MEDIA_PREVIOUSTRACK);
if (Convert.ToString(data).CompareTo("NE") == 0) SendMessageW(hwnd, WM_APPCOMMAND, hwnd, (IntPtr)APPCOMMAND_MEDIA_NEXTTRACK);
// Process the data sent by the client.
//device.AudioEndpointVolume.MasterVolumeLevelScalar = (Convert.ToInt64(data) / 100.0f);
//byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
//byte[] msg = System.Text.Encoding.ASCII.GetBytes("Successfully set to " + data);
// Send back a response.
//stream.Write(msg, 0, msg.Length);
//Console.WriteLine("Sent: {0}", data);
}
// Shutdown and end connection
client.Close();
}
}
What needs to happen to connect to the server(client code)
Code:
static void Connect(String server, String message)
{
try
{
// Create a TcpClient.
// Note, for this client to work you need to have a TcpServer
// connected to the same address as specified by the server, port
// combination.
Int32 port = 13000;
TcpClient client = new TcpClient(server, port);
// Translate the passed message into ASCII and store it as a Byte array.
Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);
NetworkStream stream = client.GetStream();
// Send the message to the connected TcpServer.
stream.Write(data, 0, data.Length);
// Close everything.
stream.Close();
client.Close();
}
catch (ArgumentNullException e)
{
MessageBox.Show("ArgumentNullException: " + e.ToString());
}
catch (SocketException e)
{
MessageBox.Show("SocketException: " + e.ToString());
}
}
So I would call Connect("192.168.1.40", "PP"); to pause/play the server(desktop running Zune)
Code:
package com.pwn.control;
import android.app.Activity;
import java.io.*;
import java.net.*;
import android.widget.*;
import android.os.Bundle;
import android.os.StrictMode;
public class ControlActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv = new TextView(this);
tv.setText("HELLO WORLD");
setContentView(tv);
run();
}
TextView tv;
public void run()
{
new Thread(new Runnable() { public void run() {
Socket socket;
try
{
InetAddress serverAddr = InetAddress.getByName("192.168.1.40");
socket = new Socket("192.168.1.40", 13000);
//socket.connect();
DataOutputStream out = new DataOutputStream(socket.getOutputStream());
out.writeBytes("PP");
//PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
//out.println("PP");
socket.close();
}
catch (Exception e)
{
tv.setText(e.toString());
//setContentView(R.layout.main);
}
}
} ).start();
}
}
Unfortunately the above code doesn't work. Kinda stuck lol... maybe someone knows more about writing android apps than I do.
http://www.youtube.com/watch?v=PMjNrd1d4FM
Got it working with an ASP site...
now the annoying part... I tried setting it up with a default IIS instance and it doesn't have permissions to use the user32.dll!!! I tried forced impersonation and tons of different tricks but for some reason it isn't getting as high permissions as the ASP.NET debugging server.
So I need to either fix the android app so it will communicate with the service, or I need to find a way to get the IIS instance enough permissions to interact with the desktop. I did set the IIS Admin service to "interact with desktop" but nothing happened.
I also tried setting up Apache 2.2 with mod_asp installed but it has the same result... blocked from interacting.
Ok I got it working but it's really really makeshift right now...
ASP website --> loopback on port 13000 --> C# app(that will actually interface with the Zune software)
I couldn't make the API call from the C# code in the ASP site because IIS doesn't have enough permissions. So since my only drawback before was that I couldn't communicate between .NET TcpListener and Java, I can just use the ASP site to make the TcpClient connection.
The good thing is you can access this interface from anything with a web browser. Just make http://computer-ip:port/ZuneControl a favorite on any device and you can control Zune from it.
http://www.youtube.com/watch?v=haVLCOY0l6U
If you're really eager to try the alpha build with IIS that's fine...
Just set up IIS like I do in the video and add port 13000 to your inbound and outbound firewall rule. I'll work on the UI when I get some time next weekend.
Here is the code for the C# app. http://pastebin.com/08kCjKQW
The web code is in the RAR file. I just copied and pasted out of that pastebin with some extra buttons.
http://tunerspotter.com/\dropbox\misc\ZuneControl.rar
In that ZuneControl folder, ZuneControl.exe is the app. Click start, then minimize it after you set up IIS. It will work for Apache installations also. I have Apache on port 82. http://sourceforge.net/projects/mod-aspdotnet/
Instruction video: http://www.youtube.com/watch?v=ClCQhmQxC7Q
Well i've been using the web interface for a few days and it kicks ass. Does exactly what i want. I can be in bed and change songs/volume from another tab in Opera.
Next weekend Ill see if i can get the program to listen on port 81 as a web service so instead of setting up IIS or apache all you have to do is open the app and click start(then minimize it)

hey are you still working on this? I would really love something like this!
well i gave up on the app and just turned it into a ASP site + windows application. so yeah i've been using it for a few months. works great, i can pull up on any web capable device and adjust my music. Whether it's my zune, tablet, computer, or phone, i can adjust volume, go back/next, and pause/play from any device. i set up port forwarding with dyndns.org so it works over 3G
Well, now that I have your attention, my REAL question is this: Is there a way to make apps like the Amazon marketplace think they're on wifi so I don't get that stupid "you can't download this because it's too big for a cellular network"?

HAHAHA I like your tactics for getting attention.
A while back I made a remark that the only way to get peoples attention in these forums is to ask if CM7 is coming out in the title and then ask the real question in the body.
Well played
Also no, there's no way to trick Amazon
I've actually been working on figuring out a way to do this.
Any app that tries to figure out how it's connected queries the same class in the system called NetworkInfo.class.
There are two methods within NetworkInfo.class that report the network type: getType() and getTypeName(). getType() returns a machine-readable answer, while getTypeName() is human-readable.
Code:
public int getType() {
return mNetworkType;
}
Code:
public String getTypeName() {
switch (mNetworkType) {
case ConnectivityManager.TYPE_WIFI:
return "WIFI";
case ConnectivityManager.TYPE_MOBILE:
return "MOBILE";
default:
return "<invalid>";
}
}
I haven't had the resources (primarily time) to dig that far into things, but if we could figure out a way to inject something between Amazon and the getType() or getTypeName() calls, we could report to it that we're on WiFi regardless of how we're actually connected.

Wow, Computer Science II is actually helping me be able to read this. So, what type of object is mNetworkType and where is it defined? We could get it to just return that its on wifi all the time. Also, do you know what Amazon calls? GetType or GetTypeName?

Interesting stuff. There's an iPhone app for jailbroken phones that performs this function on an app-by-app basis. With this code identified, something similar might be possible on Android. I haven't done any Android dev yet, so I don't know how much help I might be. Is there a way to easily (and cheaply) intercept method calls on Android? If so, there might be a way to intercept the getType and getTypeName calls and then modify them on a case-by-case basis so that the call can be diverted to a different function. I'm talking completely theoretical here...I don't know what is offered by the Android SDK.

That was exactly where my investigation has hit the wall at the moment (and then I got busy finishing my basement).
There are a couple of ways to do it, really. Someone could modify the appstore apk to wrap any calls to getType() and getTypeName(), but that would only be on that particular apk. IIRC, the market does it for large apk downloads as well.
Other apps also look at what your network type is.
I'd love to have something that allows me to toggle what the applications see, regardless of the actual state (I'm thinking of things like Verizon's Skype, etc).
The problem with all of this is that NetworkInfo.class is deep in the core OS, so intercepting any calls to it's methods might be rather difficult at best.
Edit: Also - Can we change the thread title now that we know what it's really all about?
ROTFLMFAO! Awesome thread title!

I'm guessing that making isNetworkWifi() return true would allow for downloads of large files over the cell network. I might repack the APK and post it here if I find the time.
All right, I decompiled the dex file into smali class files, made the change, recompiled, and produced an APK that does not have the wifi restriction, but I'm having problems with signing. I ran a signing tool on the APK, but even after that my phone still fails to install the app (I do have the previous version of the app uninstalled). Has anyone else had experience with this?

Yeah, sure. (For anyone else attempting to download this, it will not install in its current form).
Anyone have any luck with the signing?

I'm having troubles too. Is there any way to bypass the sign check? I assume its similar to a CRC or MD5 check.
EDIT: http://developer.android.com/guide/publishing/app-signing.html
What if you saved & signed as a different app name?

Great job reading the thread and making a relevant comment.
Aside from that: CM8 would be Honeycomb-based if it were to ever be made, which is unlikely, since it's the one version of Android that's closed-source. ICS will give rise to CM9

Hi ive written a simple application for windows phone 7 that posts a status update to the users wall. This is all working correctly except for the fact that when the status update is done it is always empty. I am trying to make it so that the user can enter what they would like to say in a text box, but obviously so far this isnt working and all that is being sent is an empty status update. I am connecting to the facebook api and the authentication all works correctly or the post would not be sent at all. Ive searched all over the web and havent found anyone with the same issue as of yet.
Here is the status update code that I am working on:
Code:
private void PostStatusUpdate(string status, Action<bool, Exception> callback)
{
var request = HttpWebRequest.Create("https://graph.facebook.com/me/feed");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.BeginGetRequestStream((reqResult) =>
{
using (var strm = request.EndGetRequestStream(reqResult))
using (var writer = new StreamWriter(strm))
{
writer.Write("access_token=" + _accessToken);
writer.Write("&message=" + HttpUtility.UrlEncode(status));
}
request.BeginGetResponse((result) =>
{
try
{
var response = request.EndGetResponse(result);
using (var rstrm = response.GetResponseStream())
{
var serializer = new DataContractJsonSerializer(typeof(FacebookPostResponse));
var postResponse = serializer.ReadObject(rstrm) as FacebookPostResponse;
callback(true, null);
}
}
catch (Exception ex)
{
callback(false, ex);
}
}, null);
}, null);
}
[DataContract]
public class FacebookPostResponse
{
[DataMember(Name = "id")]
public string Id
{
get;
set;
}
}
private void PostUpdate_Click(object sender, RoutedEventArgs e)
{
PostStatusUpdate(this.StatusText.Text, (success, ex) =>
{
this.Dispatcher.BeginInvoke(() =>
{
if (success && ex == null)
{
MessageBox.Show("Status updated");
NavigationService.Navigate(new Uri("/Views/MainPage.xaml", UriKind.Relative));
}
else
{
MessageBox.Show("Unable to update status");
}
});
});
}
Has anyone encountered this before / know any solution to this problem?
Any insights into this would be much appreciated
You are using the asyncronous method with no callback function
Looks like you should be using a callback function - See examples here
http://msdn.microsoft.com/en-us/lib...est.begingetrequeststream(v=vs.90).aspx#Y1760
http://msdn.microsoft.com/en-us/lib...brequest.begingetrequeststream(v=vs.100).aspx
Also, did the same code work at one point?
It could be as simple as not closing your connections. I ran into this in the Weather City Editor that I wrote for Windows Mobile.
When I added code to hit accuweathers site to look up the code, I had forgotten to close the connection. I would need to wait until the connection timed out before it would work again.
I think yours is differnt though, since it is updating blank.
But, you could just use GetRequestStream, which does not need the callback function, synce it is not asyncronous. See example code: http://msdn.microsoft.com/en-us/library/d4cek6cc.aspx
Thanks for the reply
Thanks for the reply, the code has never worked so far it has only posted blank facebook statuses, I will see if adding an asynchronous call back makes a difference.
Thanks
