Content license

For the purposes of licensing, the content of this web site is divided into two categories:

• Documentation content, including both static documentation and content extracted from source code modules, as well as sample code, and
• All other site content

The documentation content on this site is made available to you as part of the Android Open Source Project. This documentation, including any code shown in it, is licensed under the Apache 2.0 license, the preferred license for all parts of the of the Android Open Source Project.

Apache 2.0 is a commercial and open-source-friendly software license. The majority of the Android platform and documentation is licensed under the Apache 2.0 license. While the project strives to adhere to the preferred license, there may be exceptions, such as for documentation (code comments) extracted from a source code module that is licensed under GPLv2 or other license. In those cases, the license covering the source code module will apply to the documentation extracted from it. Source code modules that are used in the generation of documentation and have licenses that require attribution can be found in the Documentation Licences section below.
