Subject: [PATCH] Fix Android 11-14 deprecation warnings (Handler,
 BroadcastReceiver)

  - Replace deprecated Handler() with Handler(Looper.getMainLooper()) for Android 11+ compatibility
  - Add RECEIVER_NOT_EXPORTED flag for BroadcastReceiver on Android 13+
  - All changes are backwards compatible to API 18

  Tested on Android 8-14 with BT5-A hardware.

  Fixes deprecation warnings that may cause issues in future Android versions.
