• Android sending lots of SMS messages

  - by Robert Parker

  I have a app, which sends a lot of SMS messages to a central server. Each user will probably send ~300 txts/day. SMS messages are being used as a networking layer, because SMS is almost everywhere and mobile internet is not. The app is intended for use in a lot of 3rd world countries where mobile internet is not ubiquitous. When I hit a limit of 100 messages, I get a prompt for each message sent. The prompt says "A large number of SMS messages are being sent". This is not ok for the user to get prompted each time to ask if the app can send a text message. The user doesn't want to get 30 consecutive prompts. I found this android source file with google. It could be out of date, I can't tell. It looks like there is a limit of 100 sms messages every 3600000ms(1 day) for each application. http://www.netmite.com/android/mydroid/frameworks/base/telephony/java/com/android/internal/telephony/gsm/SMSDispatcher.java /** Default checking period for SMS sent without uesr permit */ private static final int DEFAULT_SMS_CHECK_PERIOD = 3600000; /** Default number of SMS sent in checking period without uesr permit */ private static final int DEFAULT_SMS_MAX_ALLOWED = 100; and /** * Implement the per-application based SMS control, which only allows * a limit on the number of SMS/MMS messages an app can send in checking * period. */ private class SmsCounter { private int mCheckPeriod; private int mMaxAllowed; private HashMap<String, ArrayList<Long>> mSmsStamp; /** * Create SmsCounter * @param mMax is the number of SMS allowed without user permit * @param mPeriod is the checking period */ SmsCounter(int mMax, int mPeriod) { mMaxAllowed = mMax; mCheckPeriod = mPeriod; mSmsStamp = new HashMap<String, ArrayList<Long>> (); } boolean check(String appName) { if (!mSmsStamp.containsKey(appName)) { mSmsStamp.put(appName, new ArrayList<Long>()); } return isUnderLimit(mSmsStamp.get(appName)); } private boolean isUnderLimit(ArrayList<Long> sent) { Long ct = System.currentTimeMillis(); Log.d(TAG, "SMS send size=" + sent.size() + "time=" + ct); while (sent.size() > 0 && (ct - sent.get(0)) > mCheckPeriod ) { sent.remove(0); } if (sent.size() < mMaxAllowed) { sent.add(ct); return true; } return false; } } Is this even the real android code? It looks like it is in the package "com.android.internal.telephony.gsm", I can't find this package on the android website. How can I disable/modify this limit? I've been googling for solutions, but I haven't found anything.

• Class initialization issues loading java.util.LogManager in Android Dalvik VM

  - by Freddy B. Rose

  I've done changes in an Android native library and installed a new system.img file but am now getting an unrelated Error on startup. I can get past it by swallowing the error but I wanted to know if anyone can explain what the issue is. The Android implementation of Logger.java claims that it is Forcing the LogManager to be initialized since its class init code performs necessary one-time setup. But this forced initialization results in a NoClassDefFoundError. I'm thinking that it has something to do with the class not having been preloaded by Zygote yet but am not that familiar with the whole class loaders and VM business. If anyone has some insight it would be greatly appreciated. Thanks. I/Zygote ( 1253): Preloading classes...

• What resolution should my Android splash screens be?

  - by Dan Fabulich

  I'm creating a splash screen that will display while my Android application loads. I'd like to create it at the correct size so Android won't auto-scale it up or down to fit the screen. But there are at least three important screen sizes I care about: 320x480, 480x854 (Droid), and 480x800 (Nexus One). I've read the documentation on supporting multiple screen sizes, but I still don't see how I'm supposed to configure different splash screens for Droid/Nexus one (they're both "hdpi" resources as far as Android is concerned), and I don't know exactly how large my splash screen should be in any case. (How tall is the OS title bar/menu in Droid? N1?) What size should I make these images, and how do I tell Android to use the correct size on a given screen?

• Becoming a better Android programmer

  - by Drew Dara-Abrams

  Any suggestions on how to become a better Android programmer? I'm past intro tutorials, which mainly focus on how to use pieces of the SDK, but I still struggle to structure big Android apps. Obviously the best use of my time is continuing with my coding projects, but I'm wondering if I should be learning more about Android particulars, solidifying my somewhat shaky Java knowledge, going back to object-oriented fundamentals or patterns...? Pointers to resources (books, example apps, sites) you've found helpful would be great.

• XMPP and Android interaction

  - by Ameya Phadke

  I am currently finding about how to build a XMPP client application on android 2.0.I came across this link which somewhat talks about the same problem.I am a newbie to android dev and thus found the solution given there to be difficult to digest. The system currently has Active MQ as a JMS provider.My job is to fed the messages coming from JMS to the XMPP server and then develope XMPP client on android 2.0 which will listen and show notification to the events pushed by the server. I have following concerns(which might sound foolish) 1.How do I push the events from JMS to the XMPP server which will in turn push them on android? 2.Which XMPP server implementation I should use?I have 3 options * Openfire: Very mature (was a commercial product), but sounds like it's heavyweight, written in Java * Prosody: Lightweight and easy to use, written in Lua. Doesn't have PubSub module yet * Tigase: Also lightweight, written in Java, supports PubSub How do I test and setup these servers.Do I need PubSub funcationality for my app? 3.For XMPP client I came across Smack API given here which is updated like 2 years back.Can anyone please tell me how do I make use of it for Android 2.0.If possible can anyone please mail me latest working Smack jar files. Thanks, Ameya

• Getting started with zxing on android

  - by amitlicht

  Hi I'm trying to add zxing to my project (add a button which calls the scanner upon press). I found this: http://groups.google.com/group/android-developers/browse_thread/thread/788eb52a765c28b5 and of course the zxing homesite: http://code.google.com/p/zxing/, but still couldn't figure out what to include in the project classpath to make it all work! as for now, I copied the classes in the first link to my project (with some package name changes), and it runs but crashes after pressing the button and trying to install the barcode scanner. some code: private void setScanButton(){ Button scan = (Button) findViewById(R.id.MainPageScanButton); scan.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { IntentIntegrator.initiateScan(MyActivity.this); } }); } resulting error (from logcat): 06-13 15:26:01.540: ERROR/AndroidRuntime(1423): Uncaught handler: thread main exiting due to uncaught exception 06-13 15:26:01.560: ERROR/AndroidRuntime(1423): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://search?q=pname:com.google.zxing.client.android } Ideas?

• does android natively support RTP and/or SCTP?

  - by user299988

  Hi, I am developing a walkie-talkie application for Android, and would like to know whether RTP and/or SCTP is natively supported in the latest version of android SDK. From whatever I have dug-up so far, the answer is no. It seems that support for SCTP is coming in JDK 7. But then, I am not sure how this will work with my android developemnt. Could you please shed some light over this? Thanks,

• Android: ImageView scales up source image

  - by legr3c

  I can't seem to get my ImageView to display its source image in its original size. The ImageView looks like this: <ImageView android:id="@+id/Logo" android:src="@drawable/logo" android:layout_width="wrap_content" android:layout_height="wrap_content" > </ImageView> The source image is 140 pixels wide, yet on the Nexus One's screen, which is 480 pixels wide it uses up half of the width. Using absolute values in px or dp for the width and height changes nothing. The image also looks very antialiased from the upscaling. Why is this happening and how can I prevent it?

• surfaceview + glsurfaceview + framelayout

  - by pohtzeyun

  Hi, I'm new at this (java and opengl) so please bear with me if the answer to the question is simple. :) I'm trying to get a camera preview screen with the ability to display 3d objects simultaneously. Having gone through the samples at the api demos, I thought combining the code for the the examples at the api demo would suffice. But somehow its not working. The forces me to shut down upon startup and the error is mentioned as null pointer exception. Could someone share with me where did I go wrong and how to proceed from there. How I did the combination for the code is as shown below: myoverview.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <android.opengl.GLSurfaceView android:id="@+id/cubes" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <SurfaceView android:id="@+id/camera" android:layout_width="fill_parent" android:layout_height="fill_parent"/> </FrameLayout> myoverview.java import android.app.Activity; import android.os.Bundle; import android.view.SurfaceView; import android.view.Window; public class MyOverView extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // camera view as the background SurfaceView cameraView = (SurfaceView) findViewById(R.id.camera); cameraView = new CameraView(this); // visual of both cubes GLSurfaceView cubesView = (GLSurfaceView) findViewById(R.id.cubes); cubesView = new GLSurfaceView(this); cubesView.setRenderer(new CubeRenderer(false)); // set view setContentView(R.layout.myoverview); } } GLSurfaceView.java import android.content.Context; class GLSurfaceView extends android.opengl.GLSurfaceView { public GLSurfaceView(Context context) { super(context); } } NOTE : I didnt list the rest of the files as they are just copies of the api demos. The cameraView refers to the camerapreview.java example and the CubeRenderer refers to the CubeRenderer.java and Cube.java example. Any help would be appreciated as I've been stuck at this for a couple of days :p Thanks Sorry, didnt realise that the coding was out of place due to formatting mistakes. :p

• Android Source Code Tree Structure

  I have downloaded Android source code but I don't find the "Kernel Directory" in the top level directory of the source code tree. Is it normal ???? or is it missing ??? /mydroid$ find . -name kernel ./bionic/libc/kernel ./vendor/htc/sapphire-open/kernel ./vendor/htc/dream-open/kernel ./dalvik/libcore/luni-kernel/src/test/java/tests/api/org/apache/harmony/kernel ./dalvik/libcore/luni-kernel/src/main/java/org/apache/harmony/kernel ./prebuilt/android-arm/kernel ./prebuilt/android-x86/kernel ./device/htc/passion/kernel

• Android installation in a mobile

  - by Sundar

  Is it possible to install Android in a normal mobile phone? I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-). Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile? Any pointer/suggestion is appreciated. Thank you in advance.

• Bluetooth connect to a RS232 adapter in android

  - by ThePosey

  Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77%5FCommands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine.

• Renaming column in Android sqlite database results in error

  - by Apophenia Overload

  I've been modifying the Notepad tutorial for Android very subtly- all I did was rename the column from title to name: Before: public static final String KEY_TITLE = "title"; ... private static final String DATABASE_CREATE = "create table notes (_id integer primary key autoincrement, " + "title text not null, body text not null);"; After: public static final String KEY_TITLE = "name"; ... private static final String DATABASE_CREATE = "create table notes (_id integer primary key autoincrement, " + "name text not null, body text not null);"; However, it always results in this: 06-10 03:29:38.421: ERROR/AndroidRuntime(344): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.android.demo.notepad1/com.android.demo.notepad1.Notepadv1}: android.database.sqlite.SQLiteException: no such column: name: , while compiling: SELECT _id, name, body FROM notes ... 06-10 03:29:38.421: ERROR/AndroidRuntime(344): Caused by: android.database.sqlite.SQLiteException: no such column: name: , while compiling: SELECT _id, name, body FROM notes Am I failing to rename something? All I am modifying is the Exercise 1 Solution program from the Notepad tutorial.

• Small ProgressDialog "spinner" for android

  - by user141146

  Hi, I've been able to use the standard "ProgressDialog" for android to show that an indeterminate task is running But I'd like to use the "smaller" progress dialog "spinner" that's used for indeterminate tasks in some of the standard Android applications like the android Market (there's a small spinning circle that's actually integrated into the application window (as opposed to floating on top of it). Does anyone know how to create the smaller progress dialog (or can someone point me in the right direction)? Thanks!

• Android - How to Use SQLiteDatabase.open?

  - by Edwin Lee

  Hi all, i'm trying to use SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS)); to create/open a database instead of making use of the SQLiteOpenHelper (because i want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, i am getting this exception for that line of code: 04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): java.lang.RuntimeException: An error occured while executing doInBackground() 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.os.AsyncTask$3.done(AsyncTask.java:200) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:234) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:258) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.FutureTask.run(FutureTask.java:122) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:648) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:673) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at java.lang.Thread.run(Thread.java:1060) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): Caused by: android.database.sqlite.SQLiteException: unable to open database file 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.dbopen(Native Method) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.<init>(SQLiteDatabase.java:1584) 04-18 09:50:03.665: ERROR/AndroidRuntime(3471): at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:638) ... Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am i just using SQLiteDatabase.openDatabase the wrong way?) Would it help if i create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that i passed in?) If creating the file manually is the way to go, is it just an empty file, or do i have to write something to it? Thanks and Regards.
