근접 경보가 작동하지 않으며 알려지지 않음

Question

근접 반경에 들어갔을 때 화재 경보가 작동하지 않는 원인은 누구인지 압니까? 저는이 문제를 해결하는데 일주일 동안 고생했습니다. 누군가가이 문제에 대해 저를 도울 수 있거나 그것을 완성하기위한 가이드를 줄 수 있다면 정말 감사 할 것입니다.

매니페스트, "ProximityReceiver"의 수신기를 설정하지 않은는 아니다 활동이지만 수신기. 다음과 같이 시도해보십시오.

<receiver android:name="ProximityReceiver" > 
     <intent-filter> 
      <action android:name="com.example.myalert" /> 
     </intent-filter> 
    </receiver> 

건배.
