Re: Nanoscope: Method-Tracing Tool for Android
#2One of the things that I would love to see would be an easy way to do a before/after accounting on some visual flourishes. "How much time does this take to do X" and check in something akin to a profile in parallel to source control. "Is this fast" is something that can be really hard to answer in retrospec and I'd love to have a tool that does something like that for Android, and it seems like nanoscope might be lightweight enough for it.

We've been building up CI tooling on top of Nanoscope. The short term goal for this is: make sure that none of our internal libraries (analytics, experimentation, etc) contribute a significant percentage of the time it takes to respond to any tap in the app. We have a lot of internal mobile libraries, so preventing perf regressions in them is a big rock.
If our CI efforts prove stable, then what you're suggesting should also be possible, if I understand it correctly.

True. Fortunately, the custom fork is very easy to install if you have a supported device (right now just 6P.
Just run `nanoscope flash`.

We're also working on creating a build for the emulator.

Quick update here: You can now use Nanoscope without flashing a device by launching the Nanoscope Emulator.
This feature was largely implemented as a result of on hackernews and reddit.
