Hmm, interesting - this file doesn't appear to have the format you'd expect based on this trace code for ART I've been using for reference. A couple questions so I can better look into this: Did you generate this dump using android studio? Or using the Debug.startMethodTracing call? What device did you use? What android version? Thanks.

[fat-fellow]

Sure.

1. Yes, just using Android Studio (sampled option). Profiler was attached from start.
2. Samsung Galaxy s7
3. Android 8.0.0 (firmware G930FXXU2ERD6) (I was able to attach the profiler to an app from start only since this version).

[rschlaikjer]

Hmm, interesting. I will try to replicate using Android studio when I have a moment. In the meantime, would you be able to take another trace, using the Debug.startMethodTracingSampling method call, and check if that works? It could be that android studio is doing something unexpected here. If that also doesn't work, this might be Samsung specific behaviour.

[fat-fellow]

I have tried and in this case everything works just fine.
