To use Facebook SDK in a project, add it as a build dependency and import it.
Using FCM you can send notification messages to your client application in order to drive user engagement. With FCM, you can send two types of messages to the client app: Notification messages and Data messages, A notification message is the more lightweight option, with a 2KB limit and a predefined set of user-visible keys.
Data messages let developers send up to 4KB of custom key-value pairs. Notification messages can contain an optional data payload, which is delivered when users tap on the notification.
Use data messages when you want to process the messages on your client app.
In the overridden method FirebaseMessagingService. So to receive messages, you should use a service that extends FirebaseMessagingService. Your service should override the onMessageReceived callback. The method onMessageReceived … will not get called if the app is in background or killed state, when the message is sent through Firebase Console.
So in this tutorial we will be sending messages via Firebase console as well as via API. Now let us create an Android application to which we can send push notifications using Firebase Notifications.
The steps will be described in five detailed yet simple parts. Includes steps to create a new Android application and set up Firebase in it. Create a new Android Project in Android Studio.
Give it a name and select the Minimum SDK on which your app will run on. I chose API When you are prompted to add an activity to your application choose Blank Activity and click on next button. In the next step click on Finish and in few seconds your application should be loaded in Android Studio.
App file of your application and add the following dependencies inside dependencies section of build.In this tutorial, we like to show you how to Read and Write text file in Android Studio. Todo We’ll create an app contains 2 buttons, 1 button will save data into the SDCard when is click and another button will read the content of the file from SDCard when is click and then display content into textview.
