resource on Android

[Pogzy]

I am working on Windows but my goal is to create an apk for android, running the tutorial as an android worked fine, even on my real device.
On windows, I used a atlas.db file in resources folder and access it sucessfully using sqlite3 this way:
con = sqlite3.connect(toga.App.app.paths.app / "resources/atlas.db")
but after building for android, I've got a runtime error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.astrofilter/org.beeware.android.MainActivity}: com.chaquo.python.PyException: OperationalError: unable to open database file

After unzipping the apk, my atlas.db file in not into the apk, do I have to declare personnal files somewhere for briefcase to find them ?
Is the real path file , and logical path toga.App.app.paths.app / "resources/atlas.db" on Windows and Android are the same? If not, how do I distinguish them at run time?

You don't need to explicitly declare data files as part of packaging the app - any file that is a folder named in your sources (or a subfolder of those folders) will be copied into your app bundle.

The toga.App.app.paths.app location won't be literally the same path on Windows and Android because the app will be in different locations - but it will be functionally the same, relative to the location of the app.

If you're having difficulty reading a database file, that's likely because the code hasn't been updated and the database file hasn't been includes as part of the app. Re-running briefcase update (or briefcase run -u) should fix that problem.
