Audio streaming application with MediaBrowserServiceCompat, ExoPlayer and Firestore

Audio Streaming on Android

Watch the app demo and see screen shots.

In this course I teach you the current best practice way to build an audio streaming application on android. To make it more interesting, I designed it to look similar to the popular music streaming app called Spotify. View screen shots.

I use the ExoPlayer library for streaming the audio files. The audio files are located online in a Firebase Firestore database.

Here's what you will see in the course:

• Every line of code is written and explained on video
• ExoPlayer (same media library used by YouTube in the mobile app)
• Streaming audio files from the internet (Firestore)
• Playlists
• Effective fragment management
• AsyncTasks
• SharedPreferences
• Effective communication with interfaces
• Services (a class specifically built to stream media files)
• Background Services that run forever
• Notifications
• Controlling playback through a notification
• Notifications and the lock screen
• Broadcast Receivers
• Glide library to download bitmaps
• RecyclerViews
• And much more...

spotify-clone's Issues

The app crashes if you press the play/pause button multiple times after the app starts.

Firestore Database structure

Can you tell what is the structure of your Firestore database and how are you linking the files from storage with the database information?

"In a production app you'd want to get this data from a cache." what does this statement mean?

In MainActivity.java

What exactly does that statement mean and how to implement it in code?
Better if you could provide code sample where we get data from cache.

error: cannot find symbol class R

error: cannot find symbol class R

Activity survive configuration changes but not survive killing by the system

Activity survive configuration changes but not survive killing by the system for example when the app was long time in background.

To simulate this issue enable "don't keep activities"
Developer options > don't keep activities

1. Enter the app click on one of the categories
2. Press home button
3. Enter the app again and click on artist

The app will crash.

Will be nice to see some advanced video on this complicate and confusing topic (ConfigurationChange, LowMemory, State loss) :)

"RelativeLayout does not need an Orientaion"

Remove horizontal orientation from the RelativeLayout at fragment_media_controller

//New to GitHub. Not sure if this is the correct format to make issue.

App Crash: getTag Null Object reference

Caused often when pressed home button i.e leaving the app and then coming back to it.

Refer master branch.

for(Fragment f: MainActivityFragmentManager.getInstance().getFragments()){
        if(f != null ){
            if(!f.getTag().equals(fragment.getTag())){
                FragmentTransaction t = getSupportFragmentManager().beginTransaction();
                t.hide(f);
                t.commit();
            }
        }
    }

Spotify clone

Calling new methods on Older Versions error

in retrieving firestore data from playlist fragment video, i encountered this error while trying to run the app.
before it worked when I tested for category fragment.

Application behaves a bit oddly over time

MediaNotificationService buttons not working

Hi geek,
Buttons of play ,previous and next in notification are not working with me
How can i control the listener for each of them and how can i make them working ?

Firestore database does not work when I use mine. [SOLVED]

App works when I use your google services json file. But not when mine, and this happens only during playlist fragment.

I could share login details of firestore if screenshot is not enough.

Handling Configuration Changes Part 1 Repository does not match the code.

This branch does not have updated code as in the video Handling Configuration Changes Part 1
I believe changes are not pushed,
