Fixed: Application crashing below API level 29 when we select the external storage.

Browse Source 
* The issue was with the `FileObserver` class constructor we used, which is introduced in SDK 29. As a result, it is not available for older versions, leading to a `NoSuchMethodError` when attempting to access it. This caused the application to crash below API level 29 when selecting external storage.
