3.0 Work in Progress 11: Bookmarks, Chrome OS, and Permissions

I recently picked up one of the new Google Pixelbooks and I will say it a pretty awesome development device.  It runs Chrome OS, Android, and Linux all at the same time and has pretty good specs (i5 cpu, 8 gb ram, 128 gb ssd) for running Android Studio.  I am able to code and deploy GMMP right on the same device which makes development really convenient when not at home.   Android apps also run in their own window which can be resized which makes UI testing on different size screens super easy.

Ignore the artifacts around the window containing GMMP.  It is a side effect of taking a screenshot i guess (it appears fine on the device)
In order to support the free form resizing of the app window, I updated the target SDK level to 27 (android 8.1).  GMMP 2.x was still on 21 (android 5.0).  The target SDK update should see some performance improvement in newer devices (although i do not know by how much).  I also added support for the android permission system they added back in 5.1.  GMMP should only ask for storage permission and possibly phone state permission (if you want to use the auto resume after a phone call finishes feature).

Anyway, the main focus of WIP 11 is bookmarks.  In the process of refactoring / rewriting the MusicService, I rewrote the Bookmarker and added a UI to show existing bookmarks.  All of the previous work I spent on creating common, reusable UI components is really paying off.  Adding a functional bookmark list UI only took roughly 15 to 30 minutes.  Similarly the Artist and Genre details UIs I showed in WIP 10 took about the same amount of time.  Since its so quick to add these UIs, I can see myself adding a bunch of optional views for some other fields like year or composer (and making 2 separate UIs for artist / album artist if the user wants to have both easily accessible)

The bookmark list will show all the currently bookmarked tracks and let you play them directly from the list (or delete them).  Like every other view i've shown in 3.0 so far, the metadata will be customizable.  For this post I just had the list items show song name and bookmarked time.  For the video below I set it up to just auto bookmark everything, but the previous bookmark settings will still be there in 3.0 (auto bookmark based of song length, m4b extension, or by folder). The video will show the song auto bookmarking when changing tracks, and then resuming at the same position when returning to the song.  It also shows the manual bookmarking and unbookmarking of the currently playing song.

My focus next will be creating a folder UI.  The folder UI is a bit more complex than the other UIs (besides maybe now playing) so I imagine its going to take awhile
