Ril and smartphone

Hi,
I follow every comment present in this form about using ril.dll for accessing cellID and so on.
I still have a problem with RIL. All compilation process work well but when I start my application on Phone (MPX220) an error responce occurs...
Thanks
Hi,
what error exactly?
error: 80004005
Using the code present in itsutils from xda-developpers.com after calling RIL_Initialize....
Hi,
Unfortunately, 80004005 is defined as 'Unspecified error' (E_FAIL), which doesn't help much. However, given that you are using a Smartphone, the probable cause is that you are using a Priviledged function. Smartphones require applications to be signed in order to use priviledged functions.
For further information about this, see here.
Thanks!! now it seem works even though some other error code 80004001 or 80070057...
Hi,
Error 800004001 is 'Not implemented error' (E_NOTIMPL) which means that a function you are trying to use is not supported by the service provider.
Error 80070057 is 'One or more arguments are not valid error' (E_INVALIDARG) which means that either an argument you are providing to a function is incorrect, or that you have not specified the valid argument specifiers (dwParams) required by some structures used in some functions.
A good place to look for what errors mean is here
thanks a lot...
One more question:
- How can I get the information that Ril_CellTowerInfo should be able to provide?
on my phone exist one process "tstutil" that is the engineering mode menu...

[Q] Development Question - NEWBIE - Android

Hi, I am just starting developing and I have been playing with the notepad sample code on android developers (the ones you get with the SDK). I have added it to the bare-bones of my app, and the first Activity opens fine and the menu works, but when the first activity opens, the debugger gives me the error
Code:
Failed to find provider info for com.example.notepad.provider.notepad
I changed all the references to com.example... to my package name that I could find, but none of them referred to the "provider"
The debugger also says that the activity is starting but I get an Activity not found exception.
It is looking for dat=content://com.example.notepad.prover.notepad/notes
I have tried to search for this reference in all the files, but I am not seeing it (or rather the search and find parts of Eclipse are not finding it.
What am I missing?
Sorry, I can do Java Applets, but this Android thing is completely new!

[Q] Stack over flow error in Android

Hi All,
In calculator application while doing some monkey testing I got this force close.
Can any one tell me what is the problem and what is the solution for this...
Most likely a programmer error and there is nothing you can really do without having the source code, changing the code piece causing it and recompiling the file.
If you could print some piece of code and, more, the error log, we could help you.

RemoteTracker for Android -Antitheft software

Hi there,
This software is an Antitheft and you can use it to track your device when it was lost or stolen. It works catching a formated SMS/EMail sent from any phone/computer and then receiving useful informations back.
You can use it to others objectives, like keep your eye in your child. Use your imagination!
You can set up to four emergengy contacts to receive SMS if the thief change your SIM card and you still can track your device.
The RemoteTracker for Android is an evolution from an old project for Windows Mobile 6 (If you want to see the entire history, please click here).
I'm justing starting this project. There are much more to come.
To send a command to RemoteTracker, send a SMS with the syntax: RT#(command)#(phone or e-mail)#(password). Example: RT#EGP#[email protected]#1234. This version answer the commands below:
help - send to you a list of commands available in Android platform;
ehelp - same as 'HELP', but send the list by e-mail;
fhelp - same as 'HELP', but send the list to your FTP server;
gp - try to get GPS coordinates and send back to cel number passed as parameter;
egp - same as 'GP', but send the list by e-mail;
fgp - same as 'GP', but send a file to your FTP server;
gi - Send informations about your phone: IMSI, IMEI and ICCID;
egi - Same as 'GI' but the answer goes by e-mail;
fgi - Same as 'GI' but the answer goes to your FTP server;
cb - your phone will make a Call Back to you. Just make a call and let the microphone open;
cellid - Retrieve informations (CELLID, LAC, MNC and MCC codes) about the tower your phone are connected. Send to you by SMS;
ecellid - same as 'CELLID', but the answer goes by e-mail;
fcellid - same as 'CELLID', but the answer goes to your FTP server;
secret - if you forget your password you can use this command to receive by SMS your personal secret question;
lostpass - used to receive your password if you forgot it. You must send the answer for your secret question, so, you can use the secret command to help you;
Commands available only in PRO version:
PICSON - Makes RemoteTracker (only PRO version) watch for new photos and send them to Default EMail Address;
PICSOFF - Makes RemoteTracker (only PRO version) stop to watch for new photos;
EPICSON - Same as PICSON, but send an E-Mail back;
EPICSOFF - Same as PICSOFF, but send an E-Mail back;
FPICSON - Same as PICSON, but send the answer to FTP server;
FPICSOFF - Same as PICSOFF, but send the answer to FTP server;
PCALLSON - Makes RemoteTracker (only PRO version) takes a photo on a call is receive or made and send it to Default EMail Address;
PCALLSOFF - Makes RemoteTracker (only PRO version) stop to take photos on calls;
EPCALLSON - Same as PCALLSON, but send an E-Mail back;
EPCALLSOFF - Same as PCALLSOFF, but send an E-Mail back;
FPCALLSON - Same as PCALLSON, but send the answer to FTP server;
FPCALLSOFF - Same as PCALLSOFF, but send the answer to FTP server;
WIPEDATA - This command will return your device to factory default and format your SD Card.
There are another features inside RemoteTracker, like:
- SIM CARD change observer;
- Automatically restore your preferences if you reinstall it. This feature is particular useful if you have a custom ROM with RemoteTracker inside. Once configured, everytime your devices boots up, your preferences will be restored;
- Works as Device Admin, so it can't be uninstalled if you don't know the password;
- And more...
This project can be multi-language. In this version there is only English (sorry about it, my english is very bad because this is not my mother language). If you want to make your own translate, I can tell how. Very simple.
If you decide to try RemoteTracker, I would like to read reviews, comments and suggestions. Remember this is a beta version and may contain bugs. Use at your own risk and with caution.
--> It is a work in progress. In future versions I will make a lot more.

Hello friends!
To test RemoteTracker please download it from here:
http://remotetracker.sourceforge.net/RemoteTracker.apk
Before your tests, please turn on the Debug option. It will make RemoteTracker write the remotetracker.txt file in the root of your memory card.
All the best,
Joubert
I just released the second beta!!!
Now, RemoteTracker can automatically turn on the Mobile and WiFi network to try get location and send EMails!
For older phones RemoteTracker also will automatically turn on the GPS! Unfortunately this is impossible if you are using new Android versions (2.3.x or so).
A few minor bugs was fixed.
All the best,
Joubert

GPS can be enabled in 2.3+ - but only if device is rooted. That's what it says in the Cerberus entry in "AppStore" [edit: AndroidMarket].
Hi!
Yes, if you have a rooted device is very easy to enable GPS remotely. But I do not recommend in any way for users to root the phones for security reasons.
I think you are talking about Market, not AppStore We are talking about Android not Apple
All the best,
Joubert
New beta 0.3!!!
Hello again,
I just released version 0.3. Now we got FTP answers back!
In Configurations I added a session to input your FTP server details. The example commands GI and GP now works with FGI and FGP as well.
Once again minor bugs was fixed. If you want to try please download the APK here: http://remotetracker.sourceforge.net/RemoteTracker.apk
As soon as possible I'll make a TODO list and a Road Map.
All the best,
Joubert
Copying my post form the old thread so I can subscribe to this one:
Wow, nice to see this make it to Android.
Some suggestions,
1: Name it something that isn't obvious in the market. Don't want a thief easily finding it in the installed apps list. Going to the market and then buying "my apps" shows you exactly what's installed. So you should name it something totally different that nobody would suspect or want to remove. Like "memory maximizer" or something like that. Probably want to keep it in the middle of the alphabet so it's not at the top or bottom of the list.
2: Maybe make a way to remotely monitor the front/rear camera. Then you could get the thief on video (and also see if it's a crowd, or some huge guy you don't want to mess with, lol).
I'll try to help test when I get another phone and more time. Right now I don't have a lot of time to work out bugs. And more importantly I only have the 1 phone, and I can't afford to have it malfunctioning (I need it for work). I'll buy a used extra phone for testing and then I'll help test.
Thank's!
Be sure I'm worry about the Name I'll post on Market. Not now. I'm trying to make it working and I'll see what I can do later.
About cameras, yes, I think we can control them. At least take pictures and send to an e-mail account. To remotely monitor the cameras, may be I need a server to receive/transmit stream. Of course this is in my todo list
All the best,
Joubert

I would rather set up my own server (or even directly stream peer to peer from the device). That way you don't get stuck with hosting fees and the app doesn't die if you decide to stop supporting it someday (not that you would).
There are many possibilities. I'll try all of them.
All the best

Another beta
Hi all,
I release another beta. Once again, if you decide to try it, please download from http://remotetracker.sourceforge.net/RemoteTracker.apk.
I edited the first post to add new features. And I have a notice...
I created a free and pro versions. The free version will have the most common commands we had in Windows Mobile. Only specific commands for Windows Mobile I can't write for Android. Pro version will have new features to come (I don't know yet).
But I don't want to charge my friends, so, if you are a beta tester or help me with anything, I'll give the PRO version for free. But it's for future now I'm engaged to finish RemoteTracker free as best as I can do.
All the best,
Joubert
Possible Bugs
Hi Joubert,
Thank you for have been developing so useful application. I believe everyone here is excited about what you are doing.
I tried your better version and here what I have to say:
1) You stated that the command format is RT#EGP#[email protected]#1234, but what if I want to use command to upload that info to FTP? Then,theoretically, I don't need to indicate my email or phone in the command. At the same time commands like "RT#FGP#1234{this is a password}", "RT#FGP##1234{this is a password}" are not recognized as valid RT commands or even failed with fatal exception. How can I upload this info to FTP, what should be the format of the command in this case?Indicating an email inside the command or phone number when sending to FTP seems a kind of redundancy.
2) Once an Fatal error appeared, it started appearing for each further VALID command which were working before. Error states the following:
Fatal error: Call to a member function query() on non-object in /celerra/webstor/root.dev/usr/sms core.php on line 234, most likely there it has some null reference there.
3) In the log file I see that its trying to send messages to invalid address substituting "@" at "?". Does it mean it sends to correct address but it writes to the logs incorrectly or is it really a bug? Because I don't receive any emails at all.For example, when sending RT#EGI#[email protected]#De41Be02AF in the logs I see that it mentioned it sent the message to "test?test.ru" instead of "[email protected]"
This is it for now. I can try to help you out with programming. I have no experience in Android development but have been developing in C# for 7+ years.
Again thanks for you effort.

I'm stuck right now. I can not go ahead because I'm not finding some answers. But soon I return to search. Very good to know there are people wainting my work to be done, because there are lots of good programs in Google Market (now Google Play).

You should use: rt#fgp##1234 The double # are still necessary. I'm working on a simpler syntax to be used in final version.
I'm worried about fatal errors. That's why I released beta versions. Please use Configurations Menu and check the Debug Options. After that you will see in the root of your memory card a file named remotetracker.txt. Send that file to me please.

Are you sending the command using another phone, the same phone or using some WEB service (like your carrier website)? There is no code to change '@' to '?'.

Notices
I almost finished writing the commands that existed in RemoteTracker for Windows Mobile (at least the ones Android can execute).
But I'm still trying to make the security of RemoteTracker to be more robust. I had Features in Windows I can't write for Android yet:
- Prompt for password when uninstalling;
- Lock / Unlock the unit with the LOCK / UNLOCK commands;
I'm not able to use the camera without the need to provide a preview to the user. According to the source code of Android that is impossible, but I saw some programs doing that, so there is a way to do that and I'm looking for this information.
If anyone knows how please help me
All the best,
Joubert

I am using Web service of my sim provider to send SMS. Didn't have a chance to try with sending SMS from the phone.

Yes, you are right.
As to the log file I will send it to you shortly.
Thank you. I'll wait for your log to see details. You can send it directly to my e-mail.

Hide Remote Tracker Application
Hi Joubertvasc:
Are you planing to make a feature to hide the Remote Tracker from the drawer and from any place of the phone. Like with the Theft Aware; you can access the application by dialing from the Phone Dialer. You enter your four code number then hit call. This will open the apllication without calling the number.
Regards;
Willie
Sounds good. I will take a look about how to do that.
Thank you.
Hi!
After a long time I'm back with a new version. This one has lots of bug fixes:
http://remotetracker.sourceforge.net/RemoteTracker.apk
My problem now is Android 3.1 and later, because they don't intercept messages all the time. They need human access the configuration module once to work. Security issue Google said... I'm trying to find an exit.
Best regards,
Joubert
G'day mate.
Long time no see. Great work on this app so far.
I've finally gotten around to installing it and play around with it a little.
I'm testing this on HTC One X with Revolution HD ROM
Here are a few ideas and tips for you to incorporate into your next version.
1. Include an option that allows users to set how many replies to get back from your software.
For Example. If I were to use #RT#GPS#1234, it currently only sends 1 reply. The problem with this is that most GPS units are accurate withing 5 - 10 meters. I tested it on myself where I am and it picks me up as being 2 houses down. If there was an option to send me 3 replies, in 60 second intervals, at least I would get the average GPS location of the phone. If your phone is stolen, it would also be a good idea to have unlimited SMS replies with 60 second intervals so I can get real time minute by minute location on where my phone is. Maybe this might be an idea for your Pro version. Have the option for how many replies to get and also an option for interval time between each reply.
2. Another idea for Pro version. Hide the RemoteTracker Icon from the Apps menu, or disguise it as a useless setting so if a thief were to look in the Apps menu, they wouldn't see it straight away, so wouldn't be forced to reset the ROM. Most thieves aren't smart enough to reset the phone as soon as they steal it, They normally wait till they get home..... but if he saw a tracking program, it would make them either turn the phone off right away, or reset the ROM right away.
3. I dont know much about Android programming, but an idea for capturing the Camera is to embed the photo into an MMS, or as an attachment in an email. Trying to muck around with FTP would be a waste of time because the average user wont have an FTP server, and you dont want to set up a central one because it would give every noob hacker a target to try and get into.
I will keep playing around and get back to you with any other problems or ideas for you.
Keep up the great work.
Loved the software on WinMo and looks like the Android version will be just as great.

[Q] Error while creating an App on an Emulator

Hello,
I am a newbie for Android App development area.
I just started learning it by watching some youttube videos.
While running a XML file for sample as "MyFirstApp" on emulator, I came cross the below thread as an error which was showing in to eclipse :
MyFirstApp] Waiting for HOME ('android.process.acore') to be launched...

And then XML file did launch the Emulator but it got stuck on "Settings" screen and was not going back to home screen .
Kindly ;let me know how can I debug this.
Thank u....
