Google Android Compatibility Definition: Android 1.6 - Manual (Page 21)

10.3. Filesystem Permissions
Device implementations MUST support the Android file access permissions model as defined in as
defined in the Security and Permissions reference [
Resources , 29].
11. Compatibility Test Suite
Device implementations MUST pass the Android Compatibility Test Suite (CTS) [ Resources , 3] available
from the Android Open Source Project, using the final shipping software on the device. Additionally,
device implementers SHOULD use the reference implementation in the Android Open Source tree as
much as possible, and 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 1.6. However, such releases will only fix behavioral bugs in the CTS
tests and will not impose any new tests, behaviors or APIs for a given platform release.
