Android: rimuovi la mia app da Device Administrator a livello di programmazione?

Question

Sto provando ad aggiungere un pulsante alla mia app per rimuoverlo da Device Administrator e sto usando il codice qui sotto, ma la mia app si blocca.

Codice: -

On Button Click: -

{ 
    ComponentName devAdminReceiver = new ComponentName(this, DemoDeviceAdminReceiver.class); 
    DevicePolicyManager dpm = (DevicePolicyManager) getSystemService(Context.DEVICE_POLICY_SERVICE); 
    dpm.removeActiveAdmin(devAdminReceiver); 
} 

Nel codice precedente, DemoDeviceAdminReceiver è una classe che estende DeviceAdminReceiver. log

Errore: -

E 'come si fa:

DevicePolicyManager mDPM = (DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); 
mDPM.removeActiveAdmin(mDeviceAdminReceiver); 

Ma è necessario aggiungere questi filtri al ricevitore in AndroidManifest.xml:

<intent-filter> 
     <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" /> 
     <action android:name="android.app.action.DEVICE_ADMIN_DISABLED" /> 
    </intent-filter> 


@Override 
public CharSequence onDisableRequested(Context context, Intent intent) { 
    return "Admin rights are beeing requested to be disabled for the app called: '" + context.getString(R.string.app_name) + "'."; 
}
