Setup

I have Adelphes.android-dev-ext installed in VSCode version 1.55.0 on Windows.

Version: 1.55.0 (system setup)
Commit: c185983a683d14c396952dd432459097bc7f757f
Date: 2021-03-30T16:01:55.261Z
Electron: 11.3.0
Chrome: 87.0.4280.141
Node.js: 12.18.3
V8: 8.7.220.31-electron.0
OS: Windows_NT x64 10.0.19042

I also have AndroidStudio installed and have installed the SDK Platform Tools installed for Android 11

I have pastedmy launch.json file and my tasks.json file

Problem

When I pick Android Attach from the debug menu, I always get this error: Running the contributed command: 'PickAndroidProcess' failed.

Am I missing a setup step?

Is it possible that I have the .json files installed in the wrong directory?

Am I missing something else simple?

Building your app automatically
This extension will not build your App. If you would like to run a build each time a debug session is started, you can add a preLaunchTask option to your launch.json configuration which invokes a build task.

.vscode/launch.json
Add a preLaunchTask item to the launch configuration:

{
"version": "0.2.0",
"configurations": [
    {
        "type": "android",
        "request": "launch",
        "name": "App Build & Launch",
        "preLaunchTask": "run gradle",
        ...
    }
]
}
