How to add a custom marker in Android systrace?

Question

I am using systrace to dig into the performance issue in my app, I am wondering if there's a way to add a tag / marker when certain event happens in the systrace result? The specific event I am looking for is input event, but it's hard to tell from systrace which input event is which. I am on Android 4.2.2

Cheers,

Johnny

You can, using android.os.Trace, but the feature wasn't added until Android 4.3 (API 18). You can find an example here.
