Android Question [Solved] Save files with API >29

[Cebuvi]

Hello,

I have developed an app that allows the user to generate and save pdf, jpg and xls files so that he can later access them and use them with other applications.

For that I create a directory in DirExternal and access it through PERMISSION_WRITE_EXTERNAL_STORAGE.

With API 29 I had to add in the manifest

SetApplicationAttribute(android:requestLegacyExternalStorage, true)

, but it is possible that with API> 29 this will not work.

I would like to know what is the best solution to save these files without having problems with future Android updates to be able to work on it.

Thank you very much.

1. You can save the file in RP.GetSafeDirDefaultExternal. File managers will be able to access this folder.
2. You can share the file from your app directly. See FileProvider example.
3. You can make your app a picker app: https://www.b4x.com/android/forum/t...om-your-app-with-file-provider.70458/#content

Thanks for the reply.

Is it foreseeable that these solutions will not have problems with future versions (30,31) of the API?

Thanks Pendrush, very interesting but complex for me.

I will have to study it slowly.
