Integrate an encrypted messaging system to android app

I am developing an android app where I have integrated a simple messenger, where users can send messages to another user when they are friends. Just messages, no files. Via firebase.

I need now to implement a better version with end to end encryption of the messages, group chat function.

Maybe also the option to send pictures, videos and maybe other files.

Most important is the end to end encryption.

Android app is developed via Android Studio and Java with a php backen with mysql database.

I need the whole yource code which I have all rights on it.

Taidot: Android, Koodaus, MySQL, PHP
