android - 从android中的GCM Intent Service无休止地获取通知

Question

我创建了一个 Activity ，它在通知发生时刷新，但我面临一个问题，即当通知到来时，它会继续发送无休止的相同通知。早些时候它工作正常，但我做了一些改变，这已经完成了。请帮我。我附上了我的代码。

GCM IntentService 类的代码

         @Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    String msgg = intent.getStringExtra("message");

     final ResultReceiver receiver = intent.getParcelableExtra("receiver");
    Bundle bundle = new Bundle();
    if (!extras.isEmpty()) {

        if (GoogleCloudMessaging.
                MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {

            sendNotification(this, msgg);


        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_DELETED.equals(messageType)) {

            sendNotification(this, msg);
            updateMyActivity(this,msgg);
            bundle.putString("result", msg);
            receiver.send(STATUS_FINISHED, bundle);

        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            updateMyActivity(this,msgg);
            sendNotification(this, msg);



        }


}

发送通知码

 private void sendNotification(Context context, String message) {

    Intent resultIntent;

    int icon = R.mipmap.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationCompat.Builder nBuilder;
    Uri alarmSound = RingtoneManager
            .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


    NotificationCompat.BigPictureStyle notiStyle = new
            NotificationCompat.BigPictureStyle();
    notiStyle.setBigContentTitle("afewtaps");
    notiStyle.setSummaryText(message);


    nBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(icon)
            .setContentTitle("afewtaps")
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setLights(Color.BLUE, 500, 500).setContentText(message)
            .setAutoCancel(true).setTicker("Notification from afewtaps")
            .setSound(alarmSound);



    resultIntent = new Intent(context,
            LoginActivity.class);
    resultIntent.putExtra("message", message);

    resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    // Show the max number of notifications here
    if (notify_no < 9) {
        notify_no = notify_no + 1;
    } else {
        notify_no = 0;
    }
    nBuilder.setContentIntent(resultPendingIntent);

    NotificationManager nNotifyMgr = (NotificationManager) context
            .getSystemService(context.NOTIFICATION_SERVICE);



    nNotifyMgr.notify(notify_no + 2, nBuilder.build());


}

发送消息进行广播

    // This function will create an intent. This intent must take as parameter the "unique_name" that you registered your activity with
static void updateMyActivity(Context context, String message) {

    Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

    //put whatever data you want to send, if any
    intent.putExtra("message", message);

    //send broadcast
    context.sendBroadcast(intent);
}

这结束了 Intent 类的代码。

现在我的 Activity 代码

         @Override
public void onResume() {
    super.onResume();
   // connectToDatabase();
    getActivity().registerReceiver(mMessageReceiver, new IntentFilter("com.google.android.c2dm.intent.RECEIVE"));
}

//Must unregister onPause()
@Override
public void onPause() {
    super.onPause();
    getActivity().unregisterReceiver(mMessageReceiver);
}


//This is the handler that will manager to process the broadcast intent
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        // Extract data included in the Intent
        String message = intent.getStringExtra("message");

        //do other stuff here

        connectToDatabase();


    }
};

Answer 1

好的。因此，您的代码发生的情况是，您正在向 Receiver 发送广播，并强制再次调用 onHandleIntent，结果调用 updateActivity 方法，该方法再次广播并无限循环。

在您的updateMyActivity 方法中，请更改:

Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

到

Intent intent = new Intent("myMessage");

这里的罪魁祸首是

com.google.android.c2dm.intent.RECEIVE

广播时调用 onHandleIntent。

此外，在 Activity 的onResume 方法中，请将TAG 更改为myMessage:

getActivity().registerReceiver(mMessageReceiver, new IntentFilter("myMessage"))
