You will need to expand DeviceAdminReceiver and

 public class DeviceAdmin extends DeviceAdminReceiver { @Override public void onEnabled(Context context, Intent intent) { Log.i(this, "admin_receiver_status_enabled"); // admin rights App.getPreferences().edit().putBoolean(App.ADMIN_ENABLED, true).commit(); //App.getPreferences() returns the sharedPreferences } @Override public CharSequence onDisableRequested(Context context, Intent intent) { return "admin_receiver_status_disable_warning"; } @Override public void onDisabled(Context context, Intent intent) { Log.info(this, "admin_receiver_status_disabled"); // admin rights removed App.getPreferences().edit().putBoolean(App.ADMIN_ENABLED, false).commit(); //App.getPreferences() returns the sharedPreferences } } 

anywhere in your application:

 DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); ComponentName mAdminName = new ComponentName(this, DeviceAdmin.class); if(mDPM != null &&mDPM.isAdminActive(mAdminName)) { // admin active }
