It was working fine until my wifi was down and I didn't know and tried to run my app to my real phone. After that, this error keeps showing. I have re-installed B4A but to no avail. As you can see, this error even happens to an empty project and every project, not only to a real device but also to an emulator. Thanks.
The projects are saved in either Windows' default Documents or Downloads folders. Yes, the APKs are there. I have also deleted AppData\Roaming\Anywhere Software\Basic4android and re-installed. The problem remains. I am using Windows 10.
I am sorry I don't quite remember, but this happens to both B4A-Bridge and Android emulator ever since my wifi incident. I will verify it and get back to you a bit later. Thanks.
I have re-installed it twice. one normal uninstall and re-install; one normal uninstall, deleted AppData\Roaming\Anywhere Software\Basic4android and re-install. Are there any Windows' registries I should/can delete manually? Thanks.
