Description

DevTools includes critical performance monitoring tools. These monitoring tools require building in Profile mode, to avoid accumulating lots of Debug mode jank. Profile mode doesn't support hot restart, which means every code change when debugging performance requires a complete app rebuild and restart.

When running DevTools, when the monitored app closes, the DevTools session disappears. Connecting to the next build of the app requires one of the following:

- Typing an IP address in the DevTools experience
- Closing the DevTools experience and re-opening from Android Studio

Both of these options are very tedious. Working through performance investigations and fixes requires dozens, if not hundreds of rebuilds in rapid succession. Needing to close and re-open DevTools for every rebuild is a huge pain point and a persistent frustration.
