Android RuntimePermissionsBasic Sample

This basic sample shows runtime permissions available in the Android M and above. It shows how to use the new runtime permissions API to check and request permissions through the support library.

Introduction

Android M introduced runtime permissions. Applications targeting M and above need to request their permissions at runtime. This sample introduces the basic use of the runtime permissions API through the support library by verifying permissions (ActivityCompat#checkSelfPermission(Context, String)), requesting permissions (ActivityCompat#requestPermissions(Activity, String[], int)) and handling the permission request callback (ActivityCompat.OnRequestPermissionsResultCallback). An application can display additional context and justification for a permission after calling ActivityCompat#shouldShowRequestPermissionRationale#shouldShowRequestPermissionRationale(Activity, String).

See the "RuntimePermissions" sample for a more complete description and reference implementation.
