This flag exists: https://developer.android.com/topic/performance/benchmarking/macrobenchmark-instrumentation-args#compilation-enabled

Will the baseline profile be used if compilation is disabled?

No. If compilation is disabled, the app will generally stay fully uncompiled, though you can separately force install the baseline profile outside the test:

adb shell cmd package compile --reset <packagename> # clear any existing compilation. note, this is currently unavailable on unrooted builds, you can instead uninstall/reinstall the app to reset compilation
adb shell am broadcast -a androidx.profileinstaller.action.INSTALL_PROFILE <packagename>/androidx.profileinstaller.ProfileInstallerReceiver
adb shell cmd package compile -f -m <packagename> speed-profile

There's also documentation for another variant here: https://d.android.com/baseline-profiles/manually-create-measure#measuring-baseline

That link should be: https://developer.android.com/topic/performance/baselineprofiles/manually-create-measure#measuring-baseline

Can't you just add a flag to keep the 1.1.0-rc01 behaviour? Looks like it is easier to stick with this version instead of executing adb commands manually.

App reinstall is meaningless to us, unfortunately, because we cannot restore user state quickly

Yes, that flag exists, as mentioned in #comment2

Correction for the broadcast

adb shell am broadcast -a androidx.profileinstaller.action.INSTALL_PROFILE <pkg>/androidx.profileinstaller.ProfileInstallReceiver
