Google Android Compatibility Definition: Android 1.6 - Manual (Page 13)

considered compatible.
5. Application Packaging Compatibility
Device implementations MUST install and run Android ".apk" files as generated by the "aapt" tool
included in the official Android SDK [
Resources , 20].
Devices implementations MUST NOT extend either the .apk, Android Manifest, or Dalvik bytecode
formats in such a way that would prevent those files from installing and running correctly on other
compatible devices. Device implementers SHOULD use the reference upstream implementation of Dalvik,
and the reference implementation's package management system.
6. Multimedia Compatibility
A compatible Android device must support the following multimedia codecs. All of these codecs are
provided as software implementations in the preferred Android implementation from the Android Open
Source Project [
Resources , 4].
Please note that neither Google nor the Open Handset Alliance make any representation that these
codecs are unencumbered by third-party patents. Those intending to use this source code in hardware or
software products are advised that implementations of this code, including in open source software or
shareware, may require patent licenses from the relevant patent holders.
