openApp() never executes, but tests display as passed

[bartekpacia]

Steps to reproduce

integration_test/example_test.dart

import 'package:flutter/material.dart';

import 'common.dart';

void main() {
  patrol(
    'counter state is the same after going to Home and switching apps',
    ($) async {
      await createApp($);

      await $(FloatingActionButton).tap();
      expect($(#counterText).text, '1');

      await $(#textField).enterText('Hello, Flutter!');
      expect($('Hello, Flutter!'), findsOneWidget);

      await $.native.pressHome(); // works
      await $.native.openApp(); // never gets called

      expect($(#counterText).text, '1');
      await $(FloatingActionButton).tap();

      expect($(#counterText).text, '2');
      expect($('Hello, Flutter!'), findsOneWidget);
    },
  );
}

1. patrol test -t integration_test/example_test.dart in example app

Actual results

After pressHome() is executed, the app is never opened again. The CLI simply reports that tests passed after a few seconds. But if we look in the logcat, there's an exception saying that app couldn't be re-opened. See attached logcat below, search for Rejecting re-init on previously-failed class java.lang.Class.

Expected results

Tests should execute and pass.

If it fails, a crash should be reported.

Same issue occurs on Samsung Galaxy S9 with Android 10 (OneUI 2.5). The logs are different, though:

Search for "openApp()". I didn't find the relevant logs, but I didn't try hard and long enough.

This issue does not occur on Samsung Galaxy S20 FE with Android 13.

Occurs on Pixel 4 API 29 emulator. I looked at the logcat but didn't find anything suspicious, though.
