IssueTracker

I am using perfetto command to take a trace following https://developer.android.com/jetpack/compose/tooling/tracing#terminal

I added "track_event" in step 2 and run the command, I got error:

pbtxt_to_pb.cc:604       Unexpected char ? (errno: 0, Success)

Could you help me with this? Here is my command:

adb shell perfetto \
  -c - --txt \
  -o /data/misc/perfetto-traces/trace \
