1 2 Android RuntimePermissions Sample (Kotlin) 3 ========================================== 4 5 This sample shows runtime permissions available in Android M and above. 6 It shows how to check and request permissions at runtime, handle backwards compatibility using the 7 support library and how to declare optional permissions for M-devices only. 8 9 Introduction 10 ------------ 11 12 Android M introduced runtime permissions. Applications targeting M and above need to request their 13 permissions at runtime. 14 15 All permissions still need to be declared in the AndroidManifest. However, when accessing APIs that 16 require a permission, the Activity or Fragment has to verify that the permission has been granted 17 or request the missing permissions using calls through the support library. 18 19 Permissions are checked through `ActivityCompat#checkSelfPermission(Context, String)` or 20 ContextCompat#checkSelfPermission(Context, String). 21 22 Permission are requested through `ActivityCompat#requestPermissions(Activity, String[], int)`, and 23 the response received in a callback to 24 `ActivityCompat.OnRequestPermissionsResultCallback#onRequestPermissionsResult(int, String[], int[])`. 25 26 Applications can provide an additional rational for the use of permissions after calling 27 `ActivityCompat#shouldShowRequestPermissionRationale(Activity,String)`. This call will return true 28 if the application should provide the user with more context on why the requested permissions is 29 needed, for example if the permission request has been denied before. 30 31 If an application targets an SDK below M, all permissions are granted at runtime and are available 32 when the application is running. The support library calls handle these checks appropriately. 33 However, if permissions have been turned off in the system settings 34 for an application targeting an SDK below M, the API will return empty or no data. 35 36 Pre-requisites 37 -------------- 38 39 - Android SDK 26 40 - Android Support Repository 41 42 Screenshots 43 ------------- 44 45 <img src="screenshots/screenshot-1.png" height="400" alt="Screenshot"/> 46 <img src="screenshots/screenshot-2.png" height="400" alt="Screenshot"/> 47 48 Getting Started 49 --------------- 50 51 This sample uses the Gradle build system.
