T_EXTENSION_INT
The value of SdkExtensions.getExtensionVersion(TIRAMISU). This is a convenience constant which provides the extension version in a similar style to Build.VERSION.SDK_INT.
Compared to calling getExtensionVersion directly, using this constant has the benefit of not having to verify the getExtensionVersion method is available.
Return
the version of the T extension, if it exists. 0 otherwise.
