For some reason I only managed to remove the "sys.android.shell".
It seems that there's something in the device that restricts "sys.android" to be deleted. if this bar file is protected, now I'm thinking that BlackBerry is using this runtimes to do something within it's core OS.
Also you are correct yessuz that Endomondo has a dependency with android, I noticed the bar to be "com.endomondo.android", same thing with my Bible app which is YouVersion "com.sirma.mobile.bible.android" (I guess).
I will not re-install the sys.android.shell for the meantime and observe if I could live with it. All this time, I thought I don't benefit from android running on top of BlackBerry, now I'm half convinced. I'm using YouVersion daily, for now I can't remove it, but I'll definitely try to remove these android dependent apps then remove the sys.android bar whenever I have enough time.
One thing for sure, I'm learning and I like it!
