R_EXTENSION_INT

The value of SdkExtensions.getExtensionVersion(R). 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 R extension, if it exists. 0 otherwise.
