SQLiteCantOpenDatabaseException Cannot open database : is not readable

Question

I am using Room DB to save data locally in android.

Now, I want to preserve the data even user uninstall the application or do clear storage.

So, I created Room DB in following location.

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS).getPath()

Everything works fine.

But if I clear the storage or uninstall the application and I open the application again, I am getting following error.

Caused by: java.util.concurrent.ExecutionException: android.database.sqlite.SQLiteCantOpenDatabaseException: Cannot open database '/storage/emulated/0/Download/database/hhcf': File /storage/emulated/0/Download/database/hhcf is not readable

This issue coming in Android 11. For Android 9 no excetion is there.

I have granted following permissions as well.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

And,

android:requestLegacyExternalStorage="true"

in application tag.

Any help would be appreciated.
