Stepping up our open source activities

As part of our continuing efforts towards openness and knowledge sharing, we are now stepping up our open source activities. For a long time, we have been one of the major contributors to the Android Open Source Project. We’ve also been active in the open developer community where we most notably published an ICS alpha release a couple of months ago. And now, we’re excited to release a couple of new open source projects that are available on our GitHub. As you can see below, we have just now released two very interesting projects as open source: the analysis tool ChkBugReport, and our WebGL implementation for Android™ 4.0.

This way, we would like to continue to be transparent, share our knowledge, and get external developer contributions to make the tools even better. On our GitHub, you can also find our Web SDK  project we published a while back, and a project called DrmLicenseService, which we will tell more about soon. Stay tuned for more information about open source projects going forward!

Android™ developers, do you frequently get Application Not Responding (ANR) messages and application crashes? Are you unsure what to do with the massive data collected from Android’s bugreport tool? We talked to Pál Szász, a software developer at Sony Ericsson, to learn about ChkBugReport, a new tool that helps you analyse your crash files. Because this tool is such a great help for our developers at Sony Ericsson, and as a part of our ambition to step up our open source activities, we want to give all of you the chance to use it by making it open source.
