KDEConnect-Android: Implement notification-panel media controls
completed by: Da-Jin Chu
mentors: Albert Vaca
KDE Connect supports controlling the music playing in the computer from an Android phone. We want to be able to do it without having to launch the app itself, from the Android notification screen like many other media players. If there is more than one player or computer, it should show the last one used by the player (if any) or the first one (otherwise).
