How to add dalvik.system.ZipPathValidator to Android Studio project

Question

I am upgrading my apps to API34 and need to address the tighter controls regarding Zip path traversal. I have legacy backup files which use paths starting with "/" which my app needs to be able to restore (unzip). The medium-term workaround for this is to call dalvik.system.ZipPathValidator.clearCallback() to avoid the 'ZipException' being thrown.

However, my project can not resolve 'ZipPathValidator' in dalvik.system.

I have updated the SDK to add all Android 14 components, and I can resolve other dalvik.system classes (eg DexClassLoader) but not 'ZipPathValidator'.

I am obviously missing something, but I'm not sure where to go from here. Any suggestions would be appreciated.

RESOLVED.

Despite having 'targetSdkVersion 34' specified in my 'build.gradle', I also had 'compileSdkVersion 33' specified.

Whilst now deprecated, compileSdkVersion obviously still takes precedence.
