Are you able to use the Android Trace class (http://developer.android.com/reference/android/os/Trace.html) from multiple threads and have it log time doing operations on each of those threads appropriately?
In particular, I have 2 threads that are each doing things and I'd like to visualize what each thread is doing at a given point in time using systrace. The docs for Trace only say that you should call #endSection from the same thread that called #beginSection, but it doesn't say whether multiple threads can be making their own calls to beginSection and endSection at the same time. Does anyone know if this is safe?
It's safe. It writes a marker to the systrace device, which is shared across multiple processes and threads.
