Android Studio -- clear application data for Instrumentation Test
With Android Test Orchestrator it is easier to provide this option via gradle script.
android {
defaultConfig {
...
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
// The following argument makes the Android Test Orchestrator run its
// "pm clear" command after each test invocation. This command ensures
// that the app's state is completely cleared between tests.
testInstrumentationRunnerArguments clearPackageData: 'true'
}

I know it's been a while, and hopefully by now you will have this issue sorted.
I ran into that same issue today, and crashed here without any solution.
But I managed to make it work by calling my task from the test configuration.
Step 1 : Go to your test configuration
Step 2 : Simply add the gradle task you created
By the way, the task in my case simply looks like this :
task clearData(type: Exec) {
def clearDataCommand = ['adb', 'shell', 'pm', 'clear', 'com.your.application']
commandLine clearDataCommand
}
Hope this will help someone :)
