Basically i'm adding a wallpaper picker for android 4.4.2 lockscreen background and when the image is set and i turn the screen off then back on to view the lockscreen my screen is going black and logcat is giving me an out of memory allocation error. So far i have tried using Bitmap decodeFile(String pathName) and i also rebased to use Bitmap decodeFile(String pathName, Options opts) but the result is the same every time...
Here is the original method used to set the image:
private static final String WALLPAPER_IMAGE_PATH =
"/data/data/com.android.settings/files/lockscreen_wallpaper.png";
private KeyguardUpdateMonitorCallback mBackgroundChanger = new KeyguardUpdateMonitorCallback() {
@Override
public void onSetBackground(Bitmap bmp) {
if (bmp != null) {
mKeyguardHost.setCustomBackground(
new BitmapDrawable(mContext.getResources(), bmp));
}
else {
File file = new File(WALLPAPER_IMAGE_PATH);
if (file.exists()) {
mKeyguardHost.setCustomBackground(
new BitmapDrawable(mContext.getResources(), WALLPAPER_IMAGE_PATH));
}
else {
mKeyguardHost.setCustomBackground(null);
}
}
updateShowWallpaper(bmp == null);
}
};
which is being called from case 1 in:
public void setCustomBackground(Drawable d) {
if (!mAudioManager.isMusicActive()) {
int mBackgroundStyle = Settings.System.getInt(mContext.getContentResolver(),
Settings.System.LOCKSCREEN_BACKGROUND_STYLE, 2);
int mBackgroundColor = Settings.System.getInt(mContext.getContentResolver(),
Settings.System.LOCKSCREEN_BACKGROUND_COLOR, 0x00000000);
switch (mBackgroundStyle) {
case 0:
d = new ColorDrawable(mBackgroundColor);
d.setColorFilter(BACKGROUND_COLOR, PorterDuff.Mode.SRC_OVER);
mCustomBackground = d;
break;
case 1:
KeyguardUpdateMonitor.getInstance(getContext()).dispatchSetBackground(null);
break;
case 2:
default:
mCustomBackground = d;
}
computeCustomBackgroundBounds(mCustomBackground);
setBackground(mBackgroundDrawable);
}
if (!ActivityManager.isHighEndGfx()) {
mCustomBackground = d;
if (d != null) {
d.setColorFilter(BACKGROUND_COLOR, PorterDuff.Mode.SRC_OVER);
}
computeCustomBackgroundBounds(mCustomBackground);
invalidate();
} else {
if (getWidth() == 0 || getHeight() == 0) {
d = null;
}
if (d == null) {
mCustomBackground = null;
setBackground(mBackgroundDrawable);
return;
}
Drawable old = mCustomBackground;
if (old == null) {
old = new ColorDrawable(0);
computeCustomBackgroundBounds(old);
}
d.setColorFilter(BACKGROUND_COLOR, PorterDuff.Mode.SRC_OVER);
mCustomBackground = d;
computeCustomBackgroundBounds(d);
Bitmap b = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
mBackgroundDrawable.draw(c);
Drawable dd = new BitmapDrawable(b);
mTransitionBackground = new TransitionDrawable(new Drawable[]{old, dd});
mTransitionBackground.setCrossFadeEnabled(true);
setBackground(mTransitionBackground);
mTransitionBackground.startTransition(200);
mCustomBackground = dd;
invalidate();
}
if (d != null) {
d.setColorFilter(BACKGROUND_COLOR, PorterDuff.Mode.SRC_OVER);
}
computeCustomBackgroundBounds(mCustomBackground);
invalidate();
}
this is my logcat output:

nothing i have tried as of yet has worked, any ideas?
EDITED
to further clarify this is what sets the image in Settings:
} else if (requestCode == REQUEST_PICK_WALLPAPER) {
FileOutputStream wallpaperStream = null;
try {
wallpaperStream = getActivity().openFileOutput(WALLPAPER_NAME,
Context.MODE_WORLD_READABLE);
} catch (FileNotFoundException e) {
return; // NOOOOO
}
Uri selectedImageUri = getLockscreenExternalUri();
Bitmap bitmap;
if (data != null) {
Uri mUri = data.getData();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(),
mUri);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, wallpaperStream);
Toast.makeText(getActivity(), getResources().getString(R.string.
background_result_successful), Toast.LENGTH_LONG).show();
Settings.System.putInt(getContentResolver(),
Settings.System.LOCKSCREEN_BACKGROUND_STYLE, 1);
updateVisiblePreferences();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} else {
try {
bitmap = BitmapFactory.decodeFile(selectedImageUri.getPath());
bitmap.compress(Bitmap.CompressFormat.PNG, 100, wallpaperStream);
} catch (NullPointerException npe) {
Log.e(TAG, "SeletedImageUri was null.");
Toast.makeText(getActivity(), getResources().getString(R.string.
background_result_not_successful), Toast.LENGTH_LONG).show();
super.onActivityResult(requestCode, resultCode, data);
return;
}
}
}
