android - 广播接收器来电（获取两次来电号码）

Question

为什么我收到两次来电？使用传出细节它可以正常工作，但它只得到一次，但我不知道传入细节会发生什么。谁能帮我？

 public void onReceive(Context context, Intent intent) {

    Log.d("APP", "ACTION:" + intent.getAction());
    //this.context = context;
    final String stringExtra = intent.getStringExtra(TelephonyManager.EXTRA_STATE);

    if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())){
        //outgoing call
        number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        Log.i("tag", "Outgoing number : " +number);
        currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
        Log.i("tag", "Date :" + currentDateTimeString);
       //doSaveCallRecord(1);
        Log.i("tag", "USER ID :" + context.getSharedPreferences("APPLICATION",Context.MODE_PRIVATE).getString(UserConstants.ID,null)+"");
    }
    if (TelephonyManager.EXTRA_STATE_RINGING.equals(stringExtra)) {
        final String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Log.d("APP", "incoming,ringing:" + incomingNumber);
        //doSaveCallRecord(0);
    }
}

<receiver android:name=".MyCallReceiver" > 
      <intent-filter> 
          <action android:name="android.intent.action.NEW_OUTGOING_CALL"/> 
          <action android:name="android.intent.action.PHONE_STATE"/> 
      </intent-filter>
</receiver>

这是我用于检查传入号码到特定号码的代码：

 @Override
public void onReceive(final Context context, Intent intent) {
    TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
    telephony.listen(new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            super.onCallStateChanged(state, incomingNumber);
            if(incomingNumber.contains("CHECKING NUMBER")){
                AudioManager audio_mngr = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
                audio_mngr.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            }
            System.out.println("incomingNumber : "+incomingNumber);
        }
    },PhoneStateListener.LISTEN_CALL_STATE);
}
