Hi Folks,

https://github.com/catapult-project/perfetto/blob/master/tools/heap_profile
https://www.perfetto.dev/#/heapprofd?id=viewing-the-data

Looking to run this on android Q device and do memory profile. Documents are minimal.

@segfaulthunter Please share details on how to run on android Application and what windows environment setup required for the same.?

ex:

tools/heap_profile --name system_server

system_server is package name of the application?

Thanks

Currently, this repository is creating 5 Mac jobs for each build. With active development and cron jobs, it has more than 300 jobs queued up (but none of them is running; they are just waiting).

This is a huge burden on the system. Please consider canceling old ones and reducing the load.

Thanks.

I meet a problem when use prefetto in android 10
