Hi!

For the following setup:

Component used: androidx.benchmark:benchmark-macro-junit4

Version used: 1.2.0-alpha09

Devices/Android versions reproduced on: Zenfone 9 (Android 13) / Pixel 3A (Android 12)

IDE: Android Studio Giraffe + AGP 7.4.1

Gradle 7.6

  private fun startup(
    compilationMode: CompilationMode,
    startupMode: StartupMode
  ) = benchmarkRule.measureRepeated(
    packageName = PROD_PACKAGE_NAME,
    metrics = listOf(
      StartupTimingMetric(),
      FrameTimingMetric()
    ),
    iterations = 5,
    compilationMode = compilationMode,
    startupMode = startupMode,
    setupBlock = {
      startActivityAndWait()
      device.signIn()
      pressHome()
    },
  ) {
    startActivityAndWait()

    device.swipeFeed()

    device.waitForIdle()
  }

I keep getting the following exception randomly during test execution:

Happens on both of my devices. It was also present in 1.2.0-alpha07 which I tested some time ago.

It seems that this occurs at a random time - sometime just at the beginning of a test or in the middle of it. Happens for both builds with and without baseline profile.

Going back to version 1.1.1 resolves the issue.
