When updating B4X to version 12.50 I get an error in the log (FileProvider is declared twice. You must remove the reference to the library or the code module.). I have tried with a new project and simply by selecting the 2 libraries I get this message.

1. This library mistakenly includes a copy of FileProvider.
2. It is not needed. You should use RuntimePermissions instead.
3. Removing FileProvider library will also work.

Only uncheck FileProvider librarry and leave PermissionsManager. PermissionsManager contains FileProvider class which save 0.5MB on the app size. So if you use PermissionsManager then do not use FileProvider library.

To be clear, if you use native B4X file provider you will get 500KB bigger apk size.

it is still in the wrong path!

Permissionmanagaer is not a internal library and should NOT be placed in the internal library folder.
Instead you shout put all Additional libraries in the additional library folder.

Yes, file provider class is wrapped from package and save 500KB. There is large number of apps which did not require androidx.core package. I have several of this apps. So if any app did not reqiure whole package it is a waste of space to use 20 lines of code and add whole package of 500KB for the file provider only. That is my logic.

Visit this link on B4X forum site:
Thread 'How to get FileProvider working without entire RuntimePermission lib or entire com.android.support:support-v4 ?' https://www.b4x.com/android/forum/t...entire-com-android-support-support-v4.145260/
