I’m dealing with a small test App to load and display a GeoPackage raster layer.
The source .gpkg file archive is on getExternalFilesDir(null) osmdroid/files path so must not be a matter of permission, but anyway I have evidences that the folder is writable and the source file is loaded and parsed.

The App works onboard an old Lg G2, Android 7 Api 25. The map shows up in the window.
On a newer Xiaomi Poco F1, Android 10 Api 29 the App fires up the below error

W/System.err: mil.nga.geopackage.GeoPackageException: Invalid GeoPackage database file
W/System.err: Caused by: mil.nga.geopackage.GeoPackageException: Failed to insert GeoPackage metadata. Name: cesaneMTB, External Path: null

Now I cannot figure out what’s on different Api … The source file is the same so why here it’s a valid gpkg and there it’s not … really confused and any debug strategy is landing to nowhere.

Gdal says

gdalinfo cesaneMTB.gpkg -oo TABLE=cesaneMTB

Any hint?
