FileNotFoundException: .android\adbkey on Windows computer

Hi,

This tool look pretty nice, but I’m having some issues to make it work on my Windows 11 computer.

When I run the command from a PowerShell, I get the following exception:

> maestro --platform android test .\login-flow.yaml
java.io.FileNotFoundException: .android\adbkey (The system cannot find the path specified)

I’m using maestro 1.5.0.

Any input?

same issue using Windows10 : java.lang.IllegalArgumentException: Illegal base64 character d Workarounds:

• Convert C:\Users<your username>.android\adbkey from CRLF to LF
• Launching maestro using git bash If we launch pwershell or cmd we need to copy the .android\adbkey folder into the folder where we launch the maestro command.

Faced the same error:

java.lang.IllegalArgumentException: Illegal base64 character d

I converted the adbkey file, in my user directory (i.e. C:\Users\<User>\.android), as suggested above to the UNIX way (LF) of ending lines (EOL), as opposed to the default on Windows (CR LF) using Notepad++ and I was able to run my tests successfully.

However, the steps in the VS Code console (powershell) are not updating (missing the green ticks?), even though the test is progressing successfully through them.

Windows Version: 10.0.19044 Build 19044

EDIT:

I noticed that I need to kill the app entirely on the emulator to get the test go through all of the test steps, otherwise it stops after launching the app
