  • Android 2.2: Screen brightness/timeout question

    - by Johan
    Im using the following code to adjust the brightness of the screen: public void SetBright(float value) { Window mywindow = getWindow(); WindowManager.LayoutParams lp = mywindow.getAttributes(); lp.screenBrightness = value; mywindow.setAttributes(lp); } But i want the brightness to be 0% for a specific time. But when i use SetBright(0.0f), i cant change it back. I made a timer that runs for a minute with 0% brightness, then turns it back to 100%. Works when i use 10% for example. But when i turn it to 0% i cant seem to wake it up again. Any ideas how to solve this?

  • Merge two bytes in java/android

    - by Shane
    Hi, I have a frame of 22 bytes. The frame is the input stream from an accelerometer via bluetooth. The acceleromter readings are a 16 bit number split over two bytes. When i try to merge the bytes with buffer[1] + buffer[2], rather than adding the bytes, it just puts the results side by side. so 1+2 = 12. Could someone tell me how to combine these two bytes to obtain the original number. (btw the bytes are sent little endian) Thanks

  • Android Emulator and adb problems

    - by Richard
    I'm having a problem in that whenever I start a emulator, either manually through the command line, or when debugging from Eclipse, it is never recognized by adb, i.e. 'adb devices' will not list it. I have to manually kill and restart adb every time I want to recognize a new emulator. Surely, something is wrong here? (I'm on Vista 64-bit)

  • Android ViewFlipper is out of control

    - by Doug Miller
    I have an app that uses a ViewFlipper to display some text and images. I have the flipper's flipinterval set to 10 seconds, but also want to allow the user to click a button that will advance the flipper. The code blow works great on 2.2, the view is changed every 10 seconds and if I click flip_button the view is changed and the auto flip steps back in 10 seconds later. The 1.5 and 1.6 versions will remember the manual advance and it will happen every time in the rotation. What am I missing? private void initFlipButton(){ final ImageView flip_button = (ImageView) findViewById(R.id.flip_button); info_button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { flipper.stopFlipping(); flipper.showNext(); flipper.startFlipping(); } }); } private void initFlipper(){ flipper = (ViewFlipper) findViewById(R.id.flip_dog); flipper.setFlipInterval(10000); flipper.setInAnimation(inFromRightAnimation()); flipper.setOutAnimation(outToLeftAnimation()); flipper.startFlipping(); }

  • Android alarm not working

    - by erdomester
    I've been struggling with this for hours. I've also checked the documentation and several topics. I found this code in two topics, both guys said the code was working perfectly, but not on my computer. The first Toast appears, but the second one never. What is wrong? public class HelloAndroid2 extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent intent = new Intent(this, AlarmReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10 * 1000), pendingIntent); Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show(); } public final class AlarmReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show(); } } }

  • Android: raise AlertDialog from background thread

    - by Stefan Klumpp
    In my activity there's some stuff going on in a background thread, which gets started in Activity_1. The processing of the background thread takes a while and I want to notify the user when it's completed via an AlertDialog. However, the user might have changed to Activity_2 or Activity_3 in the meantime and I would like to pop up the AlertDialog always in the current Activity. Any idea how to realize this?

  • Drawing translucent bitmaps using Canvas (Android)

    - by mcbitmap
    I have a Bitmap object and want to render it to a Canvas object with varying levels of translucency (i.e. make the whole bitmap partially see through). For example, I have sprites in a game (that are drawn over the top of a bitmap background) that I want to fade out from being opaque to being invisible. Can I do this without having to resort to OpenGL?

  • When is the onPreExecute called on an AsyncTask running parallely or concurrently?

    - by Debarshi Dutta
    I am using Android HoneyComb.I need to execute some tasks parallely and I am using AsyncTask's public final AsyncTask executeOnExecutor (Executor exec, Params... params) method.In each separate thread I am computing some values and I need to store then in an ArrayList.I must then sort all the values in the arrayList and then display it in the UI.Now my question is if one of the thread gets completed earlier than the other then will it immediately call the onPostExecute method or onPostExecute method will be called after all the background threads have been completed?MY program implementation depends on what occurs here.

  • Android - Loop Through strings.xml file

    - by Alexis Cartier
    I was wondering if there is anyway to loop through the strings.xml file. Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • Android WebViewClient problem

    - by deSelby
    I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?

  • Updating Android Home Screen TextView

    - by jmontex2
    Hi, How can we update the View of a Home Screen Widget on the onReceive method of AppWidgetProvider?. I am trying to update the TextView of my Home screen widget but it seems that I cant access the TextView of my AppWidgetProvider on onReceive method. Here is a sample code of my onReceive public void onReceive(Context context,Intent intent) { final String action = intent.getAction(); if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) { final int appWidgetId = intent.getExtras().getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) { this.onDeleted(context, new int[] { appWidgetId }); } } else { if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) { String msg = "null"; try { msg = intent.getStringExtra("msg"); } catch (NullPointerException e) { } Toast.makeText(context, msg, Toast.LENGTH_SHORT).show(); // code for gathering the text to update the TextView } } super.onReceive(context, intent); }

  • How to detect OpenGL capabilities without creating a GLSurfaceView (Android)

    - by ADB
    I am trying to access the OpenGL capability of the phone before deciding whether to use OpenGL or Canvas for graphics puposes. However, all the functions that I can read documentation on requires you to already have a valid OpenGL context (namely, create a GLSurfaceView and assign it a rendered. Then check the OpenGL parameters in the onSurfaceCreated). So, is there a way to check the extensions, renderer name and max texture size capability of the phone BEFORE having to create any OpenGL views?

  • Animating translation and scaling of view in Android

    - by hgpc
    I have to animate a view from state A to B with changes to its scale, position and scrolling. I know everything about state A (widthA, heightA, topA, leftA, scrollXA, scrollYA) and state B (widthB, heightB, topB, leftB, scrollXB, scrollYB). So far I wrote the following code: AnimationSet animation = new AnimationSet(true); int toXDelta; // What goes here? int toYDelta; // What goes here? TranslateAnimation translateAnimation = new TranslateAnimation(1, toXDelta, 1, toYDelta); translateAnimation.setDuration(duration); animation.addAnimation(translateAnimation); float scale = (float) widthB / (float) widthA; ScaleAnimation scaleAnimation = new ScaleAnimation(1, scale, 1, scale); scaleAnimation.setDuration(duration); animation.addAnimation(scaleAnimation); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationEnd(Animation arg0) { view.clearAnimation(); // Change view to state B } @Override public void onAnimationRepeat(Animation arg0) {} @Override public void onAnimationStart(Animation arg0) {} }); view.startAnimation(animation); Is this the right way to do this? If so, how should I calculate the values of toXDelta and toYDelta? I'm having trouble finding the exact formula. Thanks!

  • Popup window size in android

    - by Bostjan
    I'm creating a popup window in a listactivity in the event onListItemClick. LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View pop = inflater.inflate(R.layout.popupcontact, null, false); ImageView atnot = (ImageView)pop.findViewById(R.id.aNot); height = pop.getMeasuredHeight(); width = pop.getMeasuredWidth(); Log.e("pw","height: "+String.valueOf(height)+", width: "+String.valueOf(width)); atnot.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { pw.dismiss(); } }); pw = new PopupWindow(pop, width, height, true); // The code below assumes that the root container has an id called 'main' //pw.showAtLocation(v, Gravity.CENTER, 0, 0); pw.showAsDropDown(v, 10, 5); Now, the height and width variables were supposed to be height and width of the layout used for the popup window (popupcontact). But they return 0. I guess that is because the layout isn't rendered yet. Does anyone have a clue, how can I control the size of the popup window without needing to use absolute pixel numbers?
