Write an Android application - Enhancement 3

Developer is to: 1) Change the in-app chat - to the one that is based on Firebase (currently the app is using Quickblox for messaging solution). Developer also need to integrate Firebase Chat with the current UI (i.e. Post Details, Inbox (All, Selling, Buying), Side Menu (number of new messages) & Instant notification). Most importantly, the new Firebase Chat solution should be fast and should have dependable instant notification. 2) Location fix - currently app does not register location of user during login if user turned off location on device. The fix should address this. One fix is to create a highly visible button after login where user has to press the button for the app to detect location (using GPS & a notice will be shown reminding user to enable location feature). Second fix is for user to manually select their location from a list provided. 3) UI enhancement - UI change to the 2 screens. Design is provided. 4) To fix URL at Play Store - Currently the name of the app is misspelled in the URL. 5) To remove pre-loaded image on post – Currently an image is pre-loaded before actual image is loaded. Source code is available (The copyright and all other intellectual property rights of the application developed, including source codes shall belong to us). The current app is currently already on Play Store, hence it is important for login fix to be done quickly. Milestones (payment to be divided based on 5 milestones): 1. 10% upfront initial payment 2. 40% after Firebase chat change 3. 20% after Location fix 4. 15% after UI enhancement 5. 15% after URL fix & pre-loaded fix
