Permission Bitte

• Absurdly minimal API. There're only 3 static methods.
• Support LiveData
• No annotations, no worry about onRequestPermissionsResult, no worry about shouldShowRequestPermissionRationale.
• Plays nice with ArchitectureComponents. Lets your ViewModel consume the LiveData.

The API

The entry point is the PermissionBitte class. It provides three methods:

• LiveData<Permissions> permissions(FragmentActivity activity) - LiveData of all Permissions
• void ask(FragmentActivity activity) - ask for all permissions (defined in Manifest)
• void goToSettings(FragmentActivity activity) - just a helper to open the Settings

PermissionResult.java

The PermissionResult enum wraps the result of the requested permission: GRANTED, REQUEST_PERMISSION, DENIED, SHOW_RATIONAL

Permission.java

The Permission class describes the permission name and the result. It implements Parcelable so you can delegate the result within your App.

Permissions.java

Permissions gives you access to your requested permissions and their state:

• Set<Permission> getPermissionSet() - get all permissions.

It is basically all you need to access the state of your permissions. But it also offers you some convenience methods:

• Set<Permission> filter(PermissionResult permissionResult) - get a filtered set of permissions matching PermissionResult
• boolean deniedPermanently() - true if at least one permission has been denied this method
• boolean showRationale() - true if at least one permission needs to show a rationale
• boolean needAskingForPermission() - true if at least one permission has not yet been asked for
• boolean allGranted() - true if all requested permissions are granted

Android 10

Since Android 10 some permissions changed in a way that they are only allowed while the app is running. This applies for android.permission.ACCESS_FINE_LOCATION. If you need access to the location from background you need to request android.permission.ACCESS_BACKGROUND_LOCATION. So if you give only access while app is in foreground, the PermissionResult for android.permission.ACCESS_BACKGROUND_LOCATION will be SHOW_RATIONALE.

You have to handle this in your application. If this permission is mandatory for your App to work, you can re-ask for the permissions calling PermissionBitte.ask(FragmentActivity). If the permission is optional for you, you can handle this in your app.
