Error when trying to log in to tuya iot with the android sdk

Question

I completed this tuya iot integration guide on android

https://developer.tuya.com/en/docs/app-development/tutorial-for-android-final?id=Kapicb0k79vrg

but I get this error

Business {"errorCode":"DECODE_ERROR","success":false,"status":"error","errorMsg":"DECODE_ERROR"} 2023-10-15 12:29:47.768 15683-15782 Tuya com...an.stark.innovations.ecohogar D Business api: tuya.p.time.get {"t":1697390987134,"success":false,"errorCode":"SING_VALIDATE_FALED","status":"error","errorMsg":"La validación del permiso falló"}

I already have the AppKey and AppSecret configured in my manifest.xml Also check the packageName and add sha 256.

The version of tuya smart that I use is:

implementation tuyasmart version: 'com.tuya.smart:tuyasmart:3.26.5'

What I can be doing wrong?

I have really tried to increase the version of tuya smart but the error persists. I would greatly appreciate your valuable help. First of all, Thanks
