FCM PushNotification中后台应用程序时未调用的PushNotification方法

Question

我被这个问题困住了:当我的应用程序处于后台，我点击一个通知，它应该启动我想要的活动(ChatActivity)，但这并没有发生。

我不知道如何使用getIntent.getExtra()，也找不到正确的解决方案。

当单击通知时，我想用一些参数启动ChatActivity，而不是SplashScreen启动。ChatActivity应该在我的应用程序处于前台时启动。

这是我的密码：

public class FcmMessagingService extends FirebaseMessagingService
{
    private static final String TAG = "FcmMessagingService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage)
    {

        sendNotification(remoteMessage.getData().get("title"),remoteMessage.getData().get("body"));

        Log.d(TAG, "From: " + remoteMessage.getFrom());
        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0)
        {
            Log.d(TAG, "Message data payload: " + remoteMessage.getData());
            System.out.println("Message data payload: " + remoteMessage.getData());

        }

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null)
        {
            Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
            System.out.println("Message Notification Body: " + remoteMessage.getNotification().getBody());
        }

    }
    private void sendNotification(String messageTitle,String messageBody) {

        Intent intent = new Intent(this, ChatActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0 /* request code */, intent,PendingIntent.FLAG_UPDATE_CURRENT| PendingIntent.FLAG_ONE_SHOT);

        long[] pattern = {500,500,500,500,500};

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.app_icon)
                .setContentTitle(messageTitle)
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setVibrate(pattern)
                .setLights(Color.BLUE,1,1)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());


}

请你帮我解决这个问题好吗？

Answer 1

我知道答案了..。当您在Data中得到FCM的json响应时，system.out.println(getIntent.getExtra())从系统托盘中得到值，我们可以通过它来管理我们的活动。

这里是发射器ACtivity的代码

 bundle = getIntent().getExtras();
                if(bundle!=null) {
        for (String key : bundle.keySet()) {
            Object value = bundle.get(key);
            Log.d("DATA_SENT", String.format("%s %s (%s)", key, value.toString(), value.getClass().getName()));
            System.out.println("messa vale" + String.format("%s %s (%s)", key, value.toString(), value.getClass().getName()));

            if (key.equals("changeit_id")) {
                valu = value.toString();
                System.out.println("messa Value found:" + value);
            }
        }
    }
        if(!valu.equalsIgnoreCase(""))
        {
            Intent intent = new Intent(this, ChatActivity.class);
            intent.putExtra("item_id", valu);
            startActivity(intent);
            finish();
        }
        else
        {
            new Handler().postDelayed(new Runnable()
            {
                @Override
                public void run()
                {
                    Intent i = new Intent(SplashActivity.this, HomeActivity.class);
                    finish();
                    startActivity(i);
                }
            }, 3000);
        }

Answer 2

我也有过同样的问题，这就是诀窍。保存消息，在我的情况下，我使用sharedpref可以使用Const保存消息或通过Etra on意图传递消息。(快乐编码:>)

public class SplashScreen extends Acivity {
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    //When Notification is tapped
    if (getIntent().getExtras() != null) {
        //init message
        String message = String.valueOf(getIntent().getExtras().get("message"));
        String title = String.valueOf(getIntent().getExtras().get("title"));
        //save the message
        MySharedPreference.save(getApplicationContext() , "message" , message);
        MySharedPreference.save(getApplicationContext() , "title" , title);

        startActivity(new Intent(getApplicationContext() , ChatActivity.class));
        finish();
    }

在Firebase控制台上，这是我指定的键消息和标题的位置。

Firebase.Console见这里

public final class MySharedPreference {

public static void save(Context context ,String key , String value){
    SharedPreferences prefs= context.getSharedPreferences(YOUR_PACKAGE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor= prefs.edit();
    editor.putString(key,value);
    editor.apply();

}

public static String getValue(Context context ,String key){
    //if 1st time , register the user
    SharedPreferences prefs = context.getSharedPreferences(YOUR_PACKAGE_NAME, Context.MODE_PRIVATE);
    return prefs.getString(key , "");
}

}

Answer 3

根据火源处理消息，有两种类型的消息:数据和通知。如果您的应用程序处于后台，并且发送通知消息，则不会调用onMessageReceived。当不调用onMessageReceived时，这是两个例外：

通知是在应用程序处于后台时传递的。在本例中，将通知传递到设备的系统托盘。默认情况下，用户点击通知就会打开应用程序启动程序。 具有通知和数据有效负载的消息，包括后台和前台。在本例中，通知被传递到设备的系统托盘，数据有效负载在启动程序活动的目的之外传递。

如果remoteMessage.getData()和remoteMessage. getNotification()都不是null，并且app处于后台状态，那么数据部分将在启动程序活动的附加部分中接收。从此，您将不得不显式地调用您的聊天活动。
