Android 4.0 장치 관리자 수신기가 작동하지 않습니다.

Question

ICS 장치에서 모든 사용자 데이터를 지우는 아주 간단한 앱을 만들려고합니다.

나는 http://developer.android.com/guide/topics/admin/device-admin.html 및 http://marakana.com/s/post/1291/android_device_policy_administration_tutorial

에 소스 코드를 사용하여 응용 프로그램을 만들려고했습니다하지만 문제가 있어요, 아무리 내가 뭘, 관리 할 수 ​​있도록 사용자에게 메시지를 표시하기위한 방송 수신기 보이지 않는다!

누군가가이 문제에 도움을 줄 수 있다면 지금까지 내가 무엇을 얻었 는가.

매니페스트 :

<uses-sdk android:minSdkVersion="15" /> 

<application android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name"> 
    <activity  android:name="com.CheckActivityService.CheckActivityServiceActivity" 
     android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER"  /> 
     </intent-filter> 
    </activity> 
</application> 


<receiver android:name=".mDeviceAdminReceiver"

public class mDeviceAdminReceiver extends DeviceAdminReceiver {

      super.onPasswordFailed(context, intent); 
      Log.d(TAG, "onPasswordFailed");

      super.onPasswordSucceeded(context, intent); 
      Log.d(TAG, "onPasswordSucceeded"); 
    } 
} 

나는 정말 할 수 없습니다 왜 방송 수신기가 발사되지 않는지 알아 내십시오.

Answer 1

내게 어리 석다는 문제를 발견했습니다.

은 수신기에 요소를 넣는 데 필요합니다.
