  • Android Programmatically created Button Persistence

    - by WtLgi
    So in an app I'm messing around with I programmatically create some buttons. Then I setContentView(); to a different page. Then if I come back to the original page (on which I placed the programmatically created buttons), they no longer exist. I guess this makes sense as I am calling setContentView(R.layout.main); again which is just the original xml file with no data pointing to the buttons. So is there a way to have the buttons persist over such screen transitions? Thanks.

    - by Asahi
    I'd like to recognize arrival of new MMS msg (after it is downloaded to inbox). I am doing the following: private MMSContentObserver mMmsCO; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); h = new Handler(); mMmsCO = new MMSContentObserver(h); getContentResolver().registerContentObserver (Uri.parse("content://mms"), true, mMmsCO); } where private class MMSContentObserver extends ContentObserver { public MMSContentObserver(Handler h) { super(h); } @Override public boolean deliverSelfNotifications() { return false; } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); } } However, onChange is not getting called. What am I missing? Thanks in advance.

  • Detecting touch area on Android

    - by HappyAppDeveloper
    Is it possible to detect every pixel being touched? More specifically, when the user touches the screen, is it possible to track all the x-y coordinates of the cluster of points touched by the user? How can I tell the difference between when users are drawing with their thumb and when they are drawing with the tip of a finger? I would like to reflect the brush difference depending on how users touch the screen, and would also like to track x-y coordinates of all the pixels being touched over time. Thanks so much in advance for any help.

  • android listview order changed when called notifyDataSetChanged

    - by 9nix00
    hi,all. when I use notifyDataSetChanged(), the listview display order will be change . like this 3 2 1 when current activy was created. but when I change the data. it will be 1 2 3 I don't want the order changed and i dont understand why its happening. This is a piece of code from my adapter class public static class ItemAdapter extends BaseAdapter { private String[] mData; private LayoutInflater mInflater; // I called this method to change data public void setEditText(int position, final String item) { mData[position] = item; notifyDataSetChanged(); } } I change data at some dialog like this builder = new AlertDialog.Builder(ct); builder.setTitle(R.string.pickStatus) .setView(edBuffer) .setPositiveButton(R.string.save, new DialogInterface.OnClickListener() { @Override public void onClick( DialogInterface dialog, int id) { // TODO Auto-generated method stub canPop = true; final String tmp = edBuffer.getText().toString(); KbonezLog.e(String.format( "set into key %d", key)); //use mData key to set value setEditText(key, tmp); dialog.dismiss(); }})

  • How to remove strings from a compiled binary (.so)

    - by Stéphane
    How do I remove strings from / obfuscate a compiled binary? The goal is to avoid having people read the names of the functions/methods inside. It is a dynamic library (.so) compiled from C++ code for Android with the NDK tools (includes GCC) I compile with -O3 and already use arm-eabi-gcc -g mylib.so to remove debugging symbols, but when I do strings mylib.so all the names of the functions/methods are still readable.

Could you please share the best practices where to initiate the thread so that keeps running irrespective of the Activity is being shown and things to consider.

  • Android service puts multiple instances of an activity in the history

    - by HenryAdamsJr
    I'm making a music player. When you press play, it loads a notification into the OnGoing section. When you go anywhere else in the system, I want the music to keep playing. All of this is fine. The problem is that when I relaunch my activity from the Notification, it adds a task to the history stack each time, so if I hit back, I have to see the instance of Activity B from where I pressed play, and from every time I clicked on the notification to go back to Activity B. I want the instance of Activity B that I launch from the notification (via the service) to be the only copy of that Activity in the history. I've been playing around with various Intent flags and Activity attributes in the manifest, but I haven't found the proper combination.

  • android google maps my location

    - by windblow
    I have google maps activity where i would like to get my location but im facing NullPointerException... locManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this); Location location = locManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); System.out.println("loaded4"); myPoint = new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6)); System.out.println("loaded5"); I am able to get "loaded4" but not "loaded5" So NullPointer cause is between them. I also tried to use GPS_PROVIDER but it didnt work out. Yes i have all permissions in manifest. Map is able to load in if im not searhing for my loacation. Is it possible its NullPointer because before that i load some other coordinates in same class ? Maybe its emulator fault ? I can give extended code if needed. Using source from http://www.chupamobile.com/tutorial/details/53

  • Android Mock Location locks GPS on status bar

    - by Mark Manickaraj
    I created an app that uses mock locations to insert GPS coordinates. After removing the test provider via: mLocationManager.clearTestProviderLocation(mocLocationProvider); mLocationManager.removeTestProvider(mocLocationProvider); mLocationManager.removeUpdates(mLocationListener); When I launch google maps for example after exiting the app the GPS location is found and then never goes away. "Location Set By GPS" always remains on the notification bar even though my app is ended. Any ideas?

  • Android menu view, gridview or something else?

    - by dfilkovi
    I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code. Can anyone post an xml example of this?

  • android layout-land and screen-rotation handling

    - by davs
    I have layouts for portrait mode (in folder layout) and for landscape one (in the folder layout-land). This screen is located under one of the tabs, so I had to handle screen rotating (after screen has been rotated, no default screen restart occurs). I would like to update view from 'layout-land' when screen rotates to landscape mode and from 'layout' when screen rotates to portrait one. How can I do this?

  • Android Google Analytics dispatch interval

    - by Bear
    In the document, it mentions that we can have a dispatch interval such that page view will be automatically dispatched after x seconds. I have the code like the following tracker.startNewSession("UA-YOUR-ACCOUNT-HERE", 20, this); I sure trackPageView() is called as I can see those pageview are stored into "google_analytics.db" which is the database that google analyitcs used to store non-dispatching pageview. However, it doesn't send to Google Analytics after 20 seconds In log, it keeps reporting scheduling next dispatch when I call trackPageView().

  • android thread management onPause

    - by Kwan Cheng
    I have a class that extends the Thread class and has its run method implemented as so. public void run(){ while(!terminate){ if(paused){ Thread.yield(); }else{ accummulator++; } } } This thread is spawned from the onCreate method. When my UI is hidden (when the Home key is pressed) my onPause method will set the paused flag to true and yield the tread. However in the DDMS I still see the uTime of the thread accumulate and its state as "running". So my question is. What is the proper way to stop the thread so that it does not use up CPU time?

  • Override onDraw to change how the drawing occurs (Android)

    - by Casebash
    I want to change how my UI elements display, so I am overriding onDraw. The following code allows me to change a View to be drawn using PorterDuff.Mode.DARKEN. Unfortunately, this method involves creating a bitmap the size of the entire screen, then drawing to it then drawing this large bitmap the main screen again, for each UI element. This isn't at all efficient. Is it possible to achieve this in a more effecient way? @Override protected void onDraw(Canvas canvas) { //TODO: Reduce the burden from multiple drawing Bitmap bitmap=Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Config.ARGB_8888); Log.e("tmp",canvas.getClipBounds().toString()); Canvas offscreen=new Canvas(bitmap); super.onDraw(offscreen); //Then draw onscreen Paint p=new Paint(); p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DARKEN)); canvas.drawBitmap(bitmap, 0, 0, p); }

  • Followed the official android documentations but still could not use SQLite in app

    - by user366539
    My DBHelper class public class DBHelper extends SQLiteOpenHelper { public DBHelper(Context context) { super(context,"SIMPLE_DB",null,1); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE SIMPLE_TABLE ( " + "ID INTEGER PRIMARY KEY " + "DESC TEXT);"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } } Activity class public class SimpleDatabase extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); DBHelper dbHelper = new DBHelper(this); SQLiteDatabase db = dbHelper.getReadableDatabase(); db.execSQL("INSERT INTO SIMPLE_TABLE VALUES (NULL, 'test');"); Cursor cursor = db.rawQuery("SELECT * FROM SIMPLE_TABLE", null); TextView text = (TextView)findViewById(R.id.textbox); text.setText(cursor.getString(0)); } } I figure it crashed (application has stopped unexpectedly!) at SQLiteDatabase db = ... because if I commented the code out from there to the end then it worked fine. But I have no idea whatsoever why it does that. Any help would be appreciated.
