Only white screen

[ioma8]

Steps to reproduce

Versions: patrol_cli v3.0.1 patrol: 3.9.0

1. I have done android setup as described in the guide.
2. I have created simple test:

   
   import 'package:flutter/material.dart';
   import 'package:flutter_test/flutter_test.dart';
   import 'package:patrol/patrol.dart';

void main() { patrolTest( 'counter state is the same after going to home and switching apps', ($) async { await $.pumpWidgetAndSettle( MaterialApp( home: Scaffold( appBar: AppBar(title: const Text('app')), backgroundColor: Colors.blue, ), ), duration: const Duration(seconds: 10), );

  expect($('app'), findsOneWidget);

  await $.native.pressHome();
},

); }

3. I try to run it with patrol test or patrol develop command. I am running it as follows:

patrol develop -t integration_test/experiments/mytest_test.dart

### Actual results

 In patrol develop I get those error messages:

The Dart VM service is listening on http://127.0.0.1:38875/YxB7SRH_J_U=/
Patrol (native): NativeAutomatorClient created, port: 8081
Patrol (native): initialize() started
Patrol (native): initialize() failed

In both patrol test and patrol develop I am getting just white screen in the android emulator:
<img width="386" alt="image" src="https://github.com/user-attachments/assets/2babd8c2-837c-476b-913f-34bddc5a8a4c">

Interesting thing is when my colleagues run the same command in the same codebase, it runs the tests for them.

I am also attaching the errors from the "--verbose" output as it provides more information (still for me not useful as I was unable to resolve it).

Okay what fixed it after two days of debugging and trying to update SDKs etc, was wiping the android emulator. I still do not know what was the problem, but wiping the virtual device fixed it. I am writing it for future people who would encounter the same issue.

Hi, I'm glad that issue was solved by itself. If you have another not known issues that look more that something is wrong with simulator or config, don't hesitate to join our discord and ask community & our moderators. https://discord.com/invite/ukBK5t4EZg
