AS Java basic Music Streaming app - Add a few features from an *Already existing* full coded app to my own version of the app

Project duration - approx 1h Needs to be done by - 2 hours from now 2 Apps - The Original one, coded by a guy on a Youtube Tutorial - My own app, built by me through manually copying the code from the original app and making adjustments where errors were found The Original app is fully built and has all the features - It's connected to another firebase and I don't want to use it My Own app works, but does not have all of the features (Went through the tutorial and stopped at about 70% progress, so code incomplete, should be completed from the Original app code). - it's connected to my own firebase and this is the app that I want to use Each "App" has 2 parts - The Admin app and the Client app. Basically, total = 4 *I just need you to transfer the missing features from the Original app code to My own app code.* Features needing to be implemented *from the Original app* to my own app: - No play song functionality (the play pause next previous buttons etc and playing the song itself all aren't there) - when you press the Open Album Activity button, you see a Upload button which should open up your internal storage to add a photo; the button doesn't do anything. SEE SCREENSHOT "Client app [login to view URL]" : these are how the albums should look like, but also with a photo included. The albums basically act as just a folder. What's shown in the screenshot though aren't albums, they are songs. That's because I don't have the following feature - A separate menu/layer for the song lists; basically clicking each one of the albums (that will look like the screenshot above) should lead to a list of songs that are uploaded in that specific album (which will look like this) -A part of the video tutorial that I didn't do mentioned "code for songs Adapter to get songs" - don't know if it means anything i've said above, but it's certainly something I didn't do
