the activity only attaches to the framebuffer for displaying it. An icon in the notification area is displayed (it could be prettier I guess). Note: Some HTC phones won't, includng mine, get enough CPU time to do background decoding fluently, see: http://code.google.com/p/android/issues/detail?id=9663 git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27686 a1c6a512-1295-4272-9138-f99709370657
