Solves #81. The buttons were drawing before, but not the icons. Considering the XML definitions were basically the same I looked for other differences between play/pause and these buttons. The play/pause had its image set in the widget provider part of the program, while back/forward did not. Adding similar statements to set the icons for these buttons seems to fix the issue.
Tested in Nexus 4 Lollipop emulator:
Also tested physically on Android 11 on a Pixel 2 XL.
