Applications targeting M and above need to request their 13*d353a188SXin Lipermissions at runtime. 14*d353a188SXin Li 15*d353a188SXin LiAll permissions still need to be declared in the AndroidManifest. However, when accessing APIs that 16*d353a188SXin Lirequire a permission, the Activity or Fragment has to verify that the permission has been granted 17*d353a188SXin Lior request the missing permissions using calls through the support library. 18*d353a188SXin Li 19*d353a188SXin LiPermissions are checked through `ActivityCompat#checkSelfPermission(Context, String)` or 20*d353a188SXin LiContextCompat#checkSelfPermission(Context, String). 21*d353a188SXin Li 22*d353a188SXin LiPermission are requested through `ActivityCompat#requestPermissions(Activity, String[], int)`, and 23*d353a188SXin Lithe response received in a callback to 24*d353a188SXin Li`ActivityCompat.OnRequestPermissionsResultCallback#onRequestPermissionsResult(int, String[], int[])`. 25*d353a188SXin Li 26*d353a188SXin LiApplications can provide an additional rational for the use of permissions after calling 27*d353a188SXin Li`ActivityCompat#shouldShowRequestPermissionRationale(Activity,String)`. This call will return true 28*d353a188SXin Liif the application should provide the user with more context on why the requested permissions is 29*d353a188SXin Lineeded, for example if the permission request has been denied before. 30*d353a188SXin Li 31*d353a188SXin LiIf an application targets an SDK below M, all permissions are granted at runtime and are available 32*d353a188SXin Liwhen the application is running. The support library calls handle these checks appropriately. 33*d353a188SXin LiHowever, if permissions have been turned off in the system settings 34*d353a188SXin Lifor an application targeting an SDK below M, the API will return empty or no data. 35*d353a188SXin Li 36*d353a188SXin LiPre-requisites 37*d353a188SXin Li-------------- 38*d353a188SXin Li 39*d353a188SXin Li- Android SDK 26 40*d353a188SXin Li- Android Support Repository 41*d353a188SXin Li 42*d353a188SXin LiScreenshots 43*d353a188SXin Li------------- 44*d353a188SXin Li 45*d353a188SXin Li<img src="screenshots/screenshot-1.png" height="400" alt="Screenshot"/> 46*d353a188SXin Li<img src="screenshots/screenshot-2.png" height="400" alt="Screenshot"/> 47*d353a188SXin Li 48*d353a188SXin LiGetting Started 49*d353a188SXin Li--------------- 50*d353a188SXin Li 51*d353a188SXin LiThis sample uses the Gradle build system.
