Elias Projahn	e9f0bd03e7	Use the storage access framework ... Everything related to file system access has been rewritten to make use of the storage access framework. This means that the WRITE_EXTERNAL_STORAGE is no longer needed. Because of that, the dependency on permission_handler could be dropped and all code related to permission handling has been removed. To be able to open a whole document tree, the minSdkVersion was bumped to 21. Finally the file selector was rewritten using custom platform dependent code.	2020-04-11 21:59:23 +02:00
Elias Projahn	24f2022930	Backend: Fix error at first startup ... after the permissions were granted, the backend state was set to ready without checking the music library path.	2020-03-31 15:33:10 +02:00
Elias Projahn	f0644e4058	Add music library path setting ... This introduces a new state of the backend called "setup". If the music library path is not set, the backend goes into that state and the app widget can show the UI to set it up. This also introduces a new dependency on shared_preferences.	2020-03-28 10:18:52 +01:00
