How to avoid activity recreation due to change in CONFIG_ASSETS_PATHS?

After reboot the LauncherActivity is created. Then following a config change the activity is destroyed and recreated. I could in the log that ActivityTaskManager: Config changes=80000000 is printed. As per the definition, CONFIG_ASSETS_PATHS is 80000000.

If the LauncherActivity is recreated without restarting the process, it gets issues like duplicate widgets in 2 pages. The intention is that the activity should not be recreated. So all possible configs are mentioned in android:configChanges.

From the old answer it is understood that the CONFIG_ASSETS_PATHS config cannot be blocked via android:configChanges in manifest.

How to avoid recreation of activity due to change in CONFIG_ASSETS_PATHS?

    /**
 * Bit in {@link #configChanges} that indicates that the activity
 * can itself handle asset path changes.  Set from the {@link android.R.attr#configChanges}
 * attribute. This is not a core resource configuration, but a higher-level value, so its
 * constant starts at the high bits.
 * @hide We do not want apps handling this yet, but we do need some kind of bit for diffs.

public static final int CONFIG_ASSETS_PATHS = 0x80000000;
