在廣播接收器中檢測呼出結束狀態

Question

我正在使用broadcastreceiver檢測呼出並在撥號開始後啓動服務。服務已啓動。現在我想在通話結束或撥號結束時停止服務。

@Override 
public void onReceive(Context context, Intent intent) { 

     if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) { 

     intent = new Intent(context, serv.class); 
     context.startService(intent); 
    } 

    if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
      TelephonyManager.EXTRA_STATE_IDLE)) { 
     intent = new Intent(context, serv.class); 
     context.stopService(intent); 

    } 
}

try {
