Firebase Expandable Notification Show image when app is in background

Question

I am implementing FCM notifications in Android, but how does notifications differ depending on the app status (background vs. foreground)?

Answer 1

You can send messages using this rest client tool.Using this tool You can send messages to client app in background and foreground too. To send a message using API, you can use a tool called AdvancedREST Client, its a chrome extension, and send a message with the following parameters.

Rest client tool Link: https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo

use this url:- https://fcm.googleapis.com/fcm/send Content-Type:application/json Authorization:key=Your Server key From or Authoization key(see below ref)

{ "data": { "image": "https://static.pexels.com/photos/4825/red-love-romantic-flowers.jpg", "message": "Firebase Push Message Using API" "AnotherActivity": "True" }, "to" : "device id Or Device token" }

Authorization key can be obtained by visiting Google developers console and click on Credentials button on the left menu for your project. Among the API keys listed, the server key will be your authorization key.

And you need to put tokenID of the receiver in the “to” section of your POST request sent using API.

And This piece of android code //message will contain the Push Message

    String message = remoteMessage.getData().get("message1");

    //imageUri will contain URL of the image to be displayed with Notification


    String imageUri = remoteMessage.getData().get("image");

    //If the key AnotherActivity has  value as True then when the user taps on notification, in the app AnotherActivity will be opened.

    //If the key AnotherActivity has  value as False then when the user taps on notification, in the app MainActivity2 will be opened.

    String TrueOrFlase = remoteMessage.getData().get("AnotherActivity");

    //To get a Bitmap image from the URL received

    bitmap = getBitmapfromUrl(imageUri);


    sendNotification(message, bitmap, TrueOrFlase);
