When I send firebase cloud message, I touched the notification message in background of android device.

but app was not launched.

even if I set the click_action, and intent-filter in Manifest file.

I dont know what problem is.

I just want to launch app when I touch background push notification . but even if I touched background push notification, no launch the app

CodePudding user response：

did you create a service named FirebaseMessagingService or similarly named? if you have created it, you need to create intent and PendingIntent there and add it. If you do not have such a service, you need to prepare the service. While researching for you, I found a convenient example; https://www.geeksforgeeks.org/how-to-push-notification-in-android-using-firebase-cloud-messaging/
