my User id:diandian180217@gmail.com,

It was confirmed that the sampled app works well.Afterwards, when applied to an actual project, the following certificate error appears.

What should I do?

Thank you for contacting us.

This error is most likely due to a mismatch between your application ID and the application ID of your certificate.

Please refer to https://developer.myscript.com/support/account/on-device-license-management#on-device-dashboard that describes how to generate a certificate for your own application.

When creating a certificate on Android, enter the application ID that is defined with the applicationId property in your build.gradle file.

Best regards,
