title: Android Firebase Real-Time Database Triggered Push Notification
body: <p>I've created an app similar to Instagram, using Firebase as my back-end database. The app has all the features i.e users can like your post, comment on your post etc. But, now I am stuck with notifications part. I've read some docs about FCM and followed some tutorials. However, I couldn't find any specific tutorial on how to create notification with the title as the name of the person who liked/commented on the post, and body of message as the content of the comment. Do I have to use PHP and mySQL to do this all? Or it can be done solely using JAVA?</p>
