Apps Communication between two apps

[vivekmohod]

Hello,

I want to do communication between two apps just like What's App. The user will be able to see the past comments. The apps contains only text messaging. What technologies used in android to create messaging between two apps. Is it possible through firebase cloud messaging or socket programming & how. Web services will be needed to do the messaging between two apps. Please send me the link which demonstrate the messaging between 2 apps. Is there any tutorial available on net for messaging between apps in android?
