I ran into Karim Yaghmour yesterday at LinuxCon Europe. He got LTTng 0.x kernel tracer working on Android without much problem. The only "issue" he ran into was that he needed to specify the LTT_DAEMON env. var. so lttctl could find lttd (he built ltt-control tools on his host with a target directory that differed from the target installation).
