how to send FCM (Firebase Cloud Message) to a particular version of your android app? for example:- my app's latest version is 2.0 and i only want to send notifications to devices having version 2.0.
回答1:
If you're using the Notifications composer in the Firebase console to send your messages, you can target based on app version.
- Choose "User segment" under the "Target" step, select your app, and click "and" on the right side:
- In the new line that pops up, you can select "Version" and pick an app version:
回答2:
There is no built-in way to target a specific version of the app when sending messages through the FCM API. If you want to send messages to users of a specific version, you could set up a topic for each app version:
v1.0
v1.1
v2.0
...
So with that you can target users of a specific version.
If you want to send a message to all users that are not on the latest version, you can target them with a condition like this (if v2.0 is the latest version):
!('v2.0' in topics)
