Get notified each time a new user opens your app the first time or removes your app from their device.
This sample demonstrates how to send a Firebase Cloud Messaging (FCM) notification from a Analytics triggered Function.
See file functions/index.js for the code.
Sending the notification is done using the Firebase Admin SDK.
The dependencies are listed in functions/package.json.
The functions triggers every time a new user opens your app the first time or removes your app from their device.
To deploy and test the sample:
-
Create a Firebase project on the Firebase Console
-
In the Firebase Console, under
Analytics
, in theEvents
tab, mark theapp_remove
event a conversion event by switching the toggle. Thefirst_open
event should already be marked as such. -
Install the required dependencies by running
npm install
in thefunctions
directory -
Add this log to your android project:
Log.d("Firebase", "token "+ FirebaseInstanceId.getInstance().getToken());
-
Run your app on your device and copy the device token from the android logcat
-
Set the
dev_motivator.device_token
Google Cloud environment variables. For this use:firebase functions:config:set dev_motivator.device_token="your_developer_device_token"
-
Deploy your project's code using
firebase deploy
-
You'll now get a notification on your mobile when a user opens your app for the first time and when they uninstall your app.
