Welcome to the Jarek & Shawn Music sample Android app

This folder contains the source code to accompany the Google I/O 2014 codelab Android: Add Actions to a Music App.

begin

The begin folder is the starting point of the codelab. It contains an Android Studio project for a simple Android music app.

This simple music app consists of two activities or screens. A main screen showing the list of artists available in the app and an artist detail screen. Once the media player is started, a playlist fragment shows the list of currently playing songs.

These screens correspond to the following code files.

• MainActivity.java: The main entry point for the app. It shows the available artists (currently just one entry, the band "Dual Core"). This activity launches the ArtistActivity or PlaylistFragment depending on the user's choice.
• ArtistActivity.java: This activity displays information about a particular artist, including artist metadata and song list. Users can launch the PlaylistFragment to play the artist's music.

The AndroidManifest.xml file configures the app components.

PlaylistFragment.java: This fragment launches a service to play audio resources defined in the app.

• activity_main.xml,activity_artist.xml, fragment_playlist.xml: Set up the UI of the visible components.
• The class MyMusicStore mocks a music repository. It hardcodes one artist with two songs along with the associated metadata and images.
• Various other files define image, music resources, and string constants.

end

The end folder contains the resulting source code after following the codelab steps. Step 4 is an optional. If it is completed, your ArtistActivity.java file should look like the one in the step4 folder.
