Android Example Share Text File Between 2 Apps

This is just another example based on the ManageExternalStorage class provided by @agraham.
It is a response to this question.

B4ARepositoryWriter - writes a text file to an "external" directory (you can view using File Explorer).
B4ARepositoryReader - reads the text file in this directory if it exist.

I guess if we are able to read a text file then it should be possible to read keyvaluestore or sqlite files.

Note: I have modified slightly the class by modify the package name by reading Application.PackageName

Since your apps won't be published to the Play store，you could keep it simple by setting sdk level to 28 and storing files at File.DirRootExternal location, directly accessible to all 3 apps.

I was unable to get it work under Android 14 even though I set the targetSDK to 23.

I think I missed the RuntimePermissions. I can't remember why it was an issue last time.

Dim rp As RuntimePermissions
rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
Wait For B4XPage_PermissionResult (Permission As String, Result As Boolean)
Log($"${Permission} = ${Result}"$)

I agree this is much simpler.

Can you post your solution to that thread?
It will be more easier to read and obvious to the OP.

I don't think so. As mentioned by agraham, it may not allow in playstore.
