[Q&A]: How can I build MPGO in Android Studio?

[libregeek]

What are You thinking?

I am a newbie in Android Development and trying to understand how Music Player Go works under the hood. I cloned the repository on Android Studio and tried to build the application without any changes to the source code. Could you please help me to build and run the app on an emulator?

Thanks a lot. It worked.

I am curious how you implemented reading metadata from files. Is there any document which describes the approach you have implemented?

To get songs and metadata you have to run a query on Android MediaStore

fun queryForMusic(application: Application) =

fun Uri.toBitrate(context: Context): Pair<Int, Int>? {

fun Long.toAlbumArtURI(): Uri {

I just appended the given id (content://media/external/audio/albumart") to the end of the song uri
