When configuring a built, for reading the state of a GPIO (button press), the board in google things console hardware config should be GPIO Pull Up/Pull Down/none?

Thanks

Thanks... do you have an idea what OnGpioError: 19 is related to?

Not sure without looking at the full Logs, have you configured the Pins either as Input as Output?

If you're reading a pin, you need to configure it as Input, if you're outputting a signal then you need to configure it as an Output.

Yes input, but throws that erro in the logs (in red)
B4X: 
GPIOBtn1=pm.OpenGpio("BCM26")
GPIOBtn1.Direction=GPIOBtn1.DIRECTION_IN
GPIOBtn1.AddListener("GPIOBtn1")
It throws the error at the end of StateChange event.

Have you tried with any other pin?

Yes it works, until the app crashes for any erro, then the PIN gets like holded by the OS, removing the App with ADB, restarting the device, and reinstall it, solves the issue temporarily. It seems that the Ph Manager, where inits, can reset old taken pins.
