单击通知时活动错误(挂起的意图)

Question

我在我的安卓应用(FirebaseMessagingService(中实现了通知服务。当我单击通知并关闭应用程序时，打开了错误的活动。如果在应用打开(前台、后台(时收到通知，则打开的活动是正确的。

在下面的代码中，打开了启动活动(项目的第一个活动(，而不是 IntroNoti.class。 这是我的FireBaseMessagingService类的代码

public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
//Log.d(TAG, "From: " + remoteMessage.getFrom());
//Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
Globals.messageIn = true;
sendNotification(remoteMessage);
}
private void sendNotification(RemoteMessage remoteMessage) {
//Intent intent = new Intent(this, Login.class);
Intent intent = new Intent(this, IntroNoti.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.ic_launcher: R.mipmap.ic_launcher;
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(icon)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setContentText("CIAO CIAO")
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

感谢@Eugen Pechanec的建议，我在我的MainActivity中添加了这个指令。仅当通知打开应用时，才会重视"messageid"属性。 谢谢大家！

if (getIntent() != null && getIntent().getExtras() != null && getIntent().getExtras().size() > 0) {
Log.d(TAG, "Received extras in onCreate()");
Bundle extras = getIntent().getExtras();
if (!extras.getString("messageid","").isEmpty()) {
Globals.fromNotification = true;
}
}

使用带有挂起意图PendingIntent.FLAG_UPDATE_CURRENT标志。这对我来说是工作。

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplication(), CHANNEL_ID)
.setSmallIcon(R.drawable.logo)
.setContentTitle(title)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setContentIntent(getPendingIntent())
.setAutoCancel(true);
private PendingIntent getPendingIntent() {
Intent intent = new Intent(getApplication(), ConversationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
return PendingIntent.getActivity(getApplication(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
