Check out how to enable Modifier.testTag to easily access composables from UI tests. 🤖

It makes writing Baseline Profiles generators and macrobenchmarks easier!

androidx.benchmark 1.2.0-alpha10 was released today with a highly requested feature - starting with Android 14 (now in preview), Macrobench will no longer reinstall or clear app data as part of recompiling an app. You can just login once, and benchmark repeatedly. https://developer.android.com/jetpack/androidx/releases/benchmark#1.2.0-alpha10

3️⃣ Rules in a different folder

You can set custom folder(s) within your build.gradle(.kts).

For example, if you generate rules on CI, you can skip committing the rules into VCS and reference a folder instead.

2️⃣ Generated and manually written rules

If some code isn't pre-compiled and it's hard to write a generator to catch it, you can manually specify it in a custom file without worrying it would be overwritten.

Check the ADS talk for how to verify results: https://youtu.be/yJm5On5Gp4c

1️⃣ Rules per build variant

You can define the rules in these files:
- src/main/baseline-prof.txt (same as before)
- src/main/baselineProfiles/*.txt
- src/[variant]/baselineProfiles/*.txt

This is useful for variants that triggers different code, for example free vs paid app.

🆕 Baseline Profiles Improvements 🆕

AGP 8.0.0-alpha10+ brings support for multiple Baseline Profiles files within your project.

Unlocked opportunities:
1️⃣ Rules per build variant

2️⃣ Generated and manually written rules

3️⃣ Rules in a different folder

New version of UiAutomator was released yesterday!

Release notes ➡️ https://d.android.com/jetpack/androidx/releases/test-uiautomator#2.3.0-alpha02

Using a Baseline Profile frees up the JIT thread pool. This is a quick way to verify effectiveness. You can see that in Android Studio Profilers. Check out the ADS session "Making apps blazing fast with Baseline Profiles" for more details and tips from @mlykotom and @rahulrav: https://www.youtube.com/watch?v=yJm5On5Gp4c

The Performance Review episode of Android Developers Backstage is a great resource for system tracing and overall performance improvements. Very well put @tornorbye, Chet Haase and Carmen Jackson.
