Remarks
<strong> Important note: </strong> only apps with android.Manifest.permission#MANAGE_EXTERNAL_STORAGE should use this method. Otherwise, a SecurityException will be thrown.
Like #getDrawable(int), but the returned Drawable has a number of limitations to reduce its overhead as much as possible. It will never scale the wallpaper (only centering it if the requested bounds do match the bitmap bounds, which should not be typical), doesn't allow setting an alpha, color filter, or other attributes, etc. The bounds of the returned drawable will be initialized to the same bounds as the wallpaper, so normally you will not need to touch it. The drawable also assumes that it will be used in a context running in the same density as the screen (not in density compatibility mode).
