I am getting this error and I don't know how to fix it:
09-18 10:14:34.482: E/Trace(787): error opening trace file: No such file or directory (2)
09-18 10:14:34.542: W/ResourceType(787): No package identifier when getting value for resource number 0x00000000
09-18 10:14:34.683: E/BootReceiver(787): java.lang.NullPointerException
can someone tell me how to fix this error,
BroadcastReceiver java:
public class BootReceiver extends BroadcastReceiver {
private static final String TAG="BootReceiver";
@Override
public void onReceive(Context context,Intent intent) {
try {
DisplayMetrics metrics = new DisplayMetrics();
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
windowManager.getDefaultDisplay().getMetrics(metrics);
int height = metrics.heightPixels;
int width = metrics.widthPixels;
Bitmap tempbitMap = BitmapFactory.decodeResource(context.getResources(), MainActivity.tophone);
WallpaperManager wallpaperManager = WallpaperManager.getInstance(context);
wallpaperManager.setWallpaperOffsetSteps(1, 1);
wallpaperManager.suggestDesiredDimensions(width, height);
try {
wallpaperManager.setBitmap(tempbitMap);
} catch (IOException e) {
e.printStackTrace();
}
} catch(Exception e){
Log.e(TAG,e.toString());
}
}
}
Application is unable to find MainActivity.tophone
as your device is booted just and your application is yet no open it mean tophone
variable is yet initialized. So it is firing NullPointerException
because of No package identifier
it mean it is unable to find resource with a given name which actually is null.
