This sample shows runtime permissions available in the Android M and above. It shows how to check and request permissions at runtime and how to declare 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. Permissions are checked through Activity#requestPermissions(String[], int) and Fragment#requestPermissions(String[], int). Permission requests are sent through Activity#requestPermissions(String[]), and the response received in the callback Activity#onRequestPermissionsResult(int, permissions[], int[]). Applications can provide an additional rational for the use of permissions after calling Activity#shouldShowRequestPermissionRationale(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. 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.
This sample uses the Gradle build system. To build this project, use the “gradlew build” command or use “Import Project” in Android Studio.
