Android RuntimePermissions Sample

This sample shows runtime permissions available in Android M and above.
It shows how to check and request permissions at runtime, handle backwards compatibility using the
support library and how to declare optional permissions for M-devices only.


Android M introduced runtime permissions. Applications targeting M and above need to request their
permissions at runtime.
All permissions still need to be declared in the AndroidManifest. However, when accessing APIs that
require a permission, the Activity or Fragment has to verify that the permission has been granted
or request the missing permissions using calls through the support library. Permissions are checked
through ActivityCompat#checkSelfPermission(Context, String) or
ContextCompat#checkSelfPermission(Context, String).
Permission are requested through ActivityCompat#requestPermissions(Activity, String[], int), and the response
received in a callback to ActivityCompat.OnRequestPermissionsResultCallback#onRequestPermissionsResult(int, String[], int[]).
Applications can provide an additional rational for the use of permissions after calling
ActivityCompat#shouldShowRequestPermissionRationale(Activity,String). This call will return true if the
application should provide the user with more context on why the requested permissions is needed,
for example if the permission request has been denied before.

If an application targets an SDK below M, all permissions are granted at runtime and are available
when the application is running. The support library calls handle these checks appropriately.
However, if permissions have been turned off in the system settings
for an application targeting an SDK below M, the API will return empty or no data.
