Error Integrating Telpo SDK: Application package com.common.service not found

Question

Hi, I've got Telpo M1 to integrate and found an error while integrating on my project and the sample project came from DemoSDK20230423_V2.5 C1. I know it's SDK for C1 but the vendor only send that file.

When init the SDK or calling anything from SDK it will produce error like this:

The errors taken from telpo sample code

The first issue I notice is missing com.common.service

and the other issue is failed to call functions using java reflection.

how to fix that?
Thanks

Hello, thank you for your feedback.
Your M1 seems to lack the service of the new architecture SDK.

I will send this service application to you by email. Please check it.

Thank you.

Hello, maybe this SDK version is not suitable for your M1. I have sent you another SDK link by email, please check it, thank you.
