If you change android:versionCode="224" and android:versionName="2.2.4" in AndroidManifest.xml you have to change this in build.gradle file too.
Click on build.gradle in package explorer tree change your new version name and code:

Old code with HashMap
Lint warning:
Use new SparseArray(...) instead for better performance
Issue: Looks for opportunities to replace HashMaps with the more efficient SparseArray
Id: UseSparseArrays
New code with SparseArray
SparseArray methods:
//developer.android.com/reference/android/util/SparseArray.html
Map<Integer, Bitmap> _bitmapCache = new HashMap<Integer, Bitmap>();
private void fillBitmapCache() {
_bitmapCache.put(R.drawable.icon, BitmapFactory.decodeResource(getResources(), R.drawable.icon));
_bitmapCache.put(R.drawable.abstrakt, BitmapFactory.decodeResource(getResources(), R.drawable.abstrakt));
_bitmapCache.put(R.drawable.wallpaper, BitmapFactory.decodeResource(getResources(), R.drawable.wallpaper));
_bitmapCache.put(R.drawable.scissors, BitmapFactory.decodeResource(getResources(),
}
Bitmap bm = _bitmapCache.get(R.drawable.icon);
