android - Listen to incoming Whatsapp messages/notifications

Question

I'm working on a notification based app, for which I need to listen to incoming notifications. I've been able to listen to incoming calls, SMS, mail etc. I have no clue how to listen for pings or messages from friends on Whatsapp via code. Can this actually be done? If so, how? Can Accessibility Service be used for this, using Package Name as "com.whatsapp"?

Answer 1

I was able to do this using Accessibility Service . Using this, you can listen to all notification on the notification bar. I listened to application-specification by adding the package name to the Accessibility Service service info , which in this case was com.whatsapp. I couldn't read the messages, but I get notified whenever a message arrives.
