Mobile Platform as a Service:Specify a UC kernel version or an inspect debug version

Last Updated:Feb 05, 2026
Important

This document is for debugging and support purposes for existing UC SDK users only. Due to a product policy change, the UC SDK is no longer available for new applications.

This topic describes how to specify a UC kernel version or an inspect debug version.

To specify a version of the UC kernel, follow these steps:

  1. Remove the current UC dependency

  2. Add the specified UC version

Remove the current UC dependency

If you integrate mPaaS into your project using the AAR method, do not remove the current UC dependency. Instead, proceed directly to add the specified UC version.

Add the specified UC version

In the dependencies block of the build.gradle file for your Application Module, add the following code to force a dependency on a specific version. Replace version with the desired version number. For the required value, see the GAV column in the Version list. To use a debug version, use the debug GAV information from the list.

Note

For component-based integration, add the code to the dependencies block of the build.gradle file in the Application Module of your Portal project.

dependencies {
    ···
    implementation ('com.alipay.android.phone.wallet:nebulaucsdk-build:version@aar'){
        force = true
    }
    ···
}
