| 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. |
| |
| Introduction |
| ------------ |
| |
| 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. |
