Device implementations:
[C-0-1] MUST pass the Android Compatibility Test Suite (CTS) available from the Android Open Source Project, using the final shipping software on the device.
[C-0-2] MUST ensure compatibility in cases of ambiguity in CTS and for any reimplementations of parts of the reference source code.
The CTS is designed to be run on an actual device. Like any software, the CTS may itself contain bugs. The CTS will be versioned independently of this Compatibility Definition, and multiple revisions of the CTS may be released for Android ANDROID_VERSION.
Device implementations:
[C-0-3] MUST pass the latest CTS version available at the time the device software is completed.
SHOULD use the reference implementation in the Android Open Source tree as much as possible.
