IssueTracker

1. Is controlled by your ui automator commands - make sure to set a gesture margin so your gestures/flings/drags don't accidentally interact with system ui.

2. Please provide traces from runs that have issues, and we can look into them. Could be related to b/279088460

3. We've had requests for this, and we'll consider it in 1.3, but two things make this hard:

   3.1. Androidx has a no-protos-in-apis policy, so we'd have to pass you a binary config, and let you modify it (or at least pass in binary datasource protos or similar)

   3.2 Perfetto configs aren't trivial to merge together

Do you have specific things you'd like to be in the perfetto config?

4. There's an experimental (no guarantee of support) project in the androidx repo that parses and graphs benchmark output distributions, but it's more about diffing small sets of benchmark runs. That may be worth investigating: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:development/plot-benchmarks/

1. about lag in perfetto Sorry , I forget to tell the background I use Macrobenchmark for.

I am in device maker company, I'm using this macrobenchmark framework to test system performance.

When the system get slow, perfetto will not start as meant to be, there'll a lag between the time when marobenchmark starts perfetto and the time when perfetto trace really starts recording.

2. trace file please see the screenshot and trace file I upload

3. data sources I'd like to add in perfetto config

because some jank frame doesn't matter, I only interested user percepted jank frame.

device maker add some trace to record user percepted jank fame in the trace

I need open it , so that I can read in the trace by sql querying.

4. thanks , I will look it.

is there any more detail explaination about https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:development/plot-benchmarks/
