• Android insertImage and the Gallery Application

  - by Steve Jones

  I am adding a bmp file to the media store using the line below ContentResolver cr = getContentResolver(); Uri uri = Uri.parse(MediaStore.Images.Media.insertImage(cr, bmp, "name", "now")); I then go to the gallery application and it shows the image, but shows it under "Camera Pictures". Is there a way to change this to its own group, perhaps to its own group? Do I need a custom content provider for this? Thanks.

• android: using listpreference and retrieving key string...

  - by Allan

  I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?) Help would be appreciated...thank you...

• Android layout alignment issues

  - by Jake Schwartz

  So I am trying to get my layout to look like this: | button text button | So that the text is centered between my two buttons. I first tried using LinearLayouts and layout_gravity tags, but that would give me something like: | buttontextbutton | and now I have a relative layout with alignParentLeft/Right and centerInParent tags but the layout now looks like | button text buttonnnnnnnnnnnnn | Is there a way to get my layout right with text that changes lengths? Thanks, Jake

• How to stop the android soft keyboard from ever coming up in my entire application

  - by JohnnyLambada

  I'm developing an application on a hardware device that has a built-in hardware keyboard that does not slide out so is always visible (like a blackberry). Therefore, I NEVER want the soft keyboard to display for my entire application. I'm aware of another SO question that gives the following lines of code: InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0); But I don't know where to put this code to hide the soft keyboard in all places where it might possibly appear in my Activity. I have tried adding the code to Activity.onUserInteraction to no avail. It seems the keyboard appears after the onUserInteraction executes.

• Android Color Picker

  - by GuyNoir

  Does anyone know of a quick color picker widget that I could grab to use in my application? I've seen one in a few different applications that has a wheel with colors, and that you tap in the center to select, but I'm not sure where to find it. Google brings up nothing. Any color picker would be fine though. Thanks.

• [Android SDK] How to know which URL an Android application tries to visit?

  - by Ming Xie

  Hi, This is a black box test, which means I don't have any way to access the source code. Because I have to reproduce the error, file a report, and then present to the programmer (who are not our company's employee), I have to find the crashing URL / http / xhttp request. Is there any way to do so on the SDK emulator? Thanks a lot.

• Are primitive types garbage collected in Android?

  - by snctln

  I know this may be a dumb question, but my background is more in c++ and managing my own memory. I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String and Rect for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense) Anyways I was working though it some more tonight and I realized that I may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection? So a year ago every few seconds I would see a message in logcat like GC freed 4010 objects / 484064 bytes in 101ms Now I see that message every 15-90 seconds or so... So to rephrase my question: Are primitive types (int, float, boolean, etc) included when seeing this message?

• Android View.onDraw() always has a clean Canvas

  - by CaseyB

  I am trying to draw an animation. To do so I have extended View and overridden the onDraw() method. What I would expect is that each time onDraw() is called the canvas would be in teh state that I left it in and I could choose to clear it or just draw over parts of it (This is how it worked when I used a SurfaceView) but each time the canvas comes back already cleared. Is there a way that I can not have it cleared? Or maybe save the previous state into a Bitmap so I can just draw that Bitmap and then draw over top of it?

• Send a public broadcast from an AppWidget in Android

  - by greve

  I have a widget for a music player and want to be able to send broadcasts when pushing the different buttons. What I want to do is when a button is pushed, the widget sends a public broadcast to another BroadcastReceiver so it can handle the different actions. In my activity class with the BroadcastReceiver: private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (action.equals(Constants.ACTION_NEXT)) { Log.d("RECEIVER", "ACTION_NEXT"); } } }; @Override protected void onStart() { super.onStart(); IntentFilter filter = new IntentFilter(); //Widget actions filter.addAction(Constants.ACTION_NEXT); registerReceiver(broadcastReceiver, new IntentFilter(filter)); } In my Widget: public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, new Intent(Constants.ACTION_NEXT), 0); views.setOnClickPendingIntent(R.id.WidgetNextButton, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } Any help or other solutions are very much appreciated!

• ArrayAdapter need to be clear even i am creating a new one

  - by Roi

  Hello I'm having problems understanding how the ArrayAdapter works. My code is working but I dont know how.(http://amy-mac.com/images/2013/code_meme.jpg) I have my activity, inside it i have 2 private classes.: public class MainActivity extends Activity { ... private void SomePrivateMethod(){ autoCompleteTextView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_dropdown_item, new ArrayList<String>(Arrays.asList("")))); autoCompleteTextView.addTextChangedListener(new MyTextWatcher()); } ... private class MyTextWatcher implements TextWatcher { ... } private class SearchAddressTask extends AsyncTask<String, Void, String[]> { ... } } Now inside my textwatcher class i call the search address task: @Override public void afterTextChanged(Editable s) { new SearchAddressTask().execute(s.toString()); } So far so good. In my SearchAddressTask I do some stuff on doInBackground() that returns the right array. On the onPostExecute() method i try to just modify the AutoCompleteTextView adapter to add the values from the array obtained in doInBackground() but the adapter cannot be modified: NOT WORKING CODE: protected void onPostExecute(String[] addressArray) { ArrayAdapter<String> adapter = (ArrayAdapter<String>) autoCompleteDestination.getAdapter(); adapter.clear(); adapter.addAll(new ArrayList<String>(Arrays.asList(addressArray))); adapter.notifyDataSetChanged(); Log.d("SearchAddressTask", "adapter isEmpty : " + adapter.isEmpty()); // Returns true!!??! } I dont get why this is not working. Even if i run it on UI Thread... I kept investigating, if i recreate the arrayAdapter, is working in the UI (Showing the suggestions), but i still need to clear the old adapter: WORKING CODE: protected void onPostExecute(String[] addressArray) { ArrayAdapter<String> adapter = (ArrayAdapter<String>) autoCompleteDestination.getAdapter(); adapter.clear(); autoCompleteDestination.setAdapter(new ArrayAdapter<String>(NewDestinationActivity.this,android.R.layout.simple_spinner_dropdown_item, new ArrayList<String>(Arrays.asList(addressArray)))); //adapter.notifyDataSetChanged(); // no needed Log.d("SearchAddressTask", "adapter isEmpty : " + adapter.isEmpty()); // keeps returning true!!??! } So my question is, what is really happening with this ArrayAdapter? why I cannot modify it in my onPostExecute()? Why is working in the UI if i am recreating the adapter? and why i need to clear the old adapter then? I dont know there are so many questions that I need some help in here!! Thanks!!
