Comment réparer “la toile: essayez d'utiliser un papier recyclé bitmap d'erreur”?

Je suis de la création d'un RecyclerView pour afficher une Grille de photos. Lors de la sélection de l'un d'entre eux, il devrait ouvrir une nouvelle activité avec une transition.

Je suis en utilisant le Glisser de la bibliothèque à charger les photos et la transition semble horrible, parce qu'il recharge l'image de la nouvelle activité. J'ai donc dû l'enregistrer dans la mémoire cache, et ensuite l'utiliser pour la transition.

J'ai le code, mais parfois, si l'image ne se charge pas, il jette une Toile RuntimeException.

C'est le journal:

C'est le code pour ouvrir l'autre activité et enregistrer l'image en tant que cache:

private void openViewer(WallpapersAdapter.WallsHolder wallsHolder, int index, final HashMap<String, String> data) {
final Intent intent = new Intent(wallsActivity, ViewerActivity.class);
intent.putExtra("wallUrl", data.get(WallpapersActivity.WALL));
intent.putExtra("wallName", data.get(WallpapersActivity.NAME));
intent.putExtra("transitionName", ViewCompat.getTransitionName(wallsHolder.wall));
//save image from drawable
//get its path and send it to activity
Bitmap bitmap = drawableToBitmap(wallsHolder.wall.getDrawable());
//Convert to byte array and send to the other activity
Log.e("Resolution", bitmap.getWidth() + "x" + bitmap.getHeight());
try {
//Write file
String filename = "bitmap.png";
FileOutputStream stream = this.openFileOutput(filename, Context.MODE_PRIVATE);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
//Cleanup
stream.close();
bitmap.recycle();
//Pop intent
intent.putExtra("image", filename);
} catch (Exception e) {
e.printStackTrace();
}
ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(
this, wallsHolder.wall, ViewCompat.getTransitionName(wallsHolder.wall));
startActivity(intent, options.toBundle());
}
public static Bitmap drawableToBitmap (Drawable drawable) {
Bitmap bitmap = null;
if (drawable instanceof BitmapDrawable) {
BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
if(bitmapDrawable.getBitmap() != null) {
return bitmapDrawable.getBitmap();
}
}
if(drawable.getIntrinsicWidth() <= 0 || drawable.getIntrinsicHeight() <= 0) {
bitmap = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888); //Single color bitmap will be created of 1x1 pixel
} else {
bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
}
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
drawable.draw(canvas);
return bitmap;
}

Que pouvais-je faire pour régler ce problème? Merci à l'avance.
