Open Devices

For some of the Xperia™ devices, we provide Android™ Open Source Project (AOSP) device configurations on GitHub. This means that the software will be open for you as a developer to use and contribute to. This is a way for us to support the open Android community, and it is also a tool for us to facilitate and verify contributions to AOSP.

Hero Open Source Developer

One of the goals in Sony’s Open Device projects is to replace as many pre-built binaries as possible with features and functionalities that can be built from AOSP source code. In this on-going work, we have received important contributions from many of you open source community developers. To recognize your work, we will acknowledge a selected Hero Open Source Developer once every three months.

The Hero Open Source Developer will be the person who submits the best accepted commits to any open source project or to our Open Device projects on SonyXperiaDev GitHub. The Hero Open Source Developer will be presented here and will receive a device from Sony as a reward.

To take part and potentially become a Hero Open Source Developer, simply submit your commits to our Open Device projects on the SonyXperiaDev GitHub.

Anyone submitting to our open source projects can be selected as Hero Open Source Developer, except for Sony Mobile partners or employees working with Sony Developer World. A developer cannot be selected as Hero Open Source Developer more than once per year. We will select a new winner once every four months.
