Modify an Android application & Web side..

This is for our private social network project, overall the source code are here with me, it is based on PHP site and Android Studio also in app purchases ready. there is something need to be done here: - apps need can be opened in offline mode withoit signing out and can show some last stream. and when there's a connection the apps will synchronize the data within the server or vice-versa. especially... for message it will show the history of message all and profile too also some last stream.. otherwise no need (just print no connection on the apps) - Fixing some notification : right now it only shows : you've got new comments it needed to be done like this = you've got new comment by (user), also it need expand notification function for messaging too. - Add additional section for profile (family name) and it is mandatory fields when user signing up (first time user) - Member Approval system by admin. - Session and non member can see nothing of the site. - verify by email or sms. - Change Gallery to be embed with profile (on apps layout), and whenever someone post in gallery, it will be shows on stream too. - Share receiver. - Add stickers layout and systems (stickers can be used on chat and comments - it also organized as category folder ( with thumbnail images) also add in app purchases for it which admin can set for it, upload new stickers too. - Add new button for site announcements and it will get some categories too. - google account integration. - fix messaging for pending status, delivered status and read. - Video preview before upload, photo preview must can be swiped to other photos, photo cropping system. - ability to post link with preview. - ability to select some message, forward, and copy.
