Changes to Verify as discussed in Issues

[trife]

@chaneylc I think we just go full in on SAF for the update. We can switch from the created folder approach to using the system level folder for the sample files since it won't be important if they're deleted upon uninstall.

@SidMalladi it looks like MainActivity was not merged properly it has conflict markers and does not compile.

@SidMalladi there are still conflict markers in multiple files. It looks like the project was not merged correctly.

You need to write a simple document provider: https://developer.android.com/guide/topics/providers/create-document-provider So that users can access the sample files, otherwise they are hidden in the app's internal storage.

FileProvider should be sufficient: https://developer.android.com/reference/androidx/core/content/FileProvider

Alternatively you can create a dialog that lets the user select the sample files when importing, as discussed previously.
