This starts a Media3 MediaSession when the service starts. A custom player class gets passed into that session to receive commands from other apps and the android os.
Currently we pad out some dummy items to make SimpleBasePlayer think we can do next and previous tracks.
MPD handles the threading for the native calls so we can just directly call the bridge from the player class.
Dagger and hilt give us dependency injection which makes it easier to split up parts of the app. This lets us easily split out things like logging and paves the way to migrate off preferences to DataStore
This also remove the process name on the service to pull eveything into one process so we don't have to do IPC to pass logs around. This lets us use the same instances of injected classes between the UI and the service side.
This changes lets us use the latest UI design from Google, Material 3.
Google only provides the material UI 3 themes for compose, compose only works with kotlin.
Most of the Android specific meson code has been removed and replaced with
the grade build system.
The new meson build scripts build and move the libmpd.so binaries into the correct
location that gradle expects. After than gradle handles building the rest of the Android app.
Icons and banners have been updated for the modern app packaging expectations.
For reference here was the figma template Google provides that I used to back the png versions
for older versions of Android <https://www.figma.com/community/file/1283953738855070149>
