This is the third in a series of tips that supplement the XperiaTM game developer recommendations. This tip expands on Packaging recommendation PK3 in the list of game developer recommendations: Any APK file larger than 5MB should be installed directly to the SD card.
A couple of weeks ago, Sony Ericsson announced the new Xperia™ active – a compact Android smartphone designed for consumers with an active lifestyle. A truly unique feature of the Xperia™ active lies in its pressure sensor for barometric measuring. Developers can use this sensor in apps, by accessing it through the Android sensor API.
This tutorial provides some tips and code examples to get your app to work with the pressure sensor.
This is the second in a series of tips that supplement the Xperia™ game developer recommendations. This tip expands on Input recommendation IN5 in the list of game developer recommendations: A game should query the possible hardware capabilities of the platform to check if they exist on the current device.

Hard to get images scaled correctly for your application? Are your images too large and causing memory problems? Or are they scaled incorrectly with a poor user experience as a result? To find a good solution for this, we asked Andreas Agvard from the Sony Ericsson software department to help shed some light on this topic.
The Xperia™ PLAY incorporates Qualcomm’s 1 GHz Snapdragon processor with an Adreno™ 205 graphics processor platform. In this article, Matthew Rusch, a Staff Engineer for the Advanced Content Group at Qualcomm, will share some practical advice on how you can optimize mobile graphics applications, specifically shader performance, for the Xperia™ PLAY.
Sony Ericsson’s latest Xperia™ smartphones, such as Xperia™ PLAY, Xperia™ arc, and Xperia™ neo, support Adreno™ Profiler for Xperia™, a tool to help developers optimise their use of the Adreno 205 graphics processor. Using the Adreno™ Profiler for Xperia™, you can fine tune your code for optimal graphics performance.
This article gives an overview of the Adreno™ Profiler for Xperia™ and identifies some of its key features. For simplicity, the tool will be referred to as the Profiler in the remainder of the article.
Do you want to maximise the quality of the Android™ games that you develop for Xperia™ devices such as Xperia™ PLAY? Developer World has documented a core set of recommendations to keep in mind when developing Android games for Xperia™ devices. By following the recommendations, you can ensure a consistent level of quality in the games you develop for these devices.
Since the launch of the unlock boot loader site, we have received a lot of really great feedback. The Sony Ericsson Developer Program wants to continue to build on this open dialogue with external developers.
Developers and advanced users can now unlock the boot loader, which is the first step to be able to flash your own image. Now we have seen quite a few comments in different forums like the XDA forum, where developers run into problems when building their own image, and and trying to flash the image using Fastboot. With the help of our Master Software Architect, James Jacobsson, we put together a short article on how to do this.
Before moving on, we’d like to remind you again that there is no turning back when unlocking the boot loader. You may void the warranty of the phone, and you will not be able to revert the phone to a locked or original state if you unlock it.
When designing your game for the Xperia™ PLAY or other Android™ devices, Sony Ericsson highly recommends that you enable the Move to SD card option. This will make your gaming files movable to external storage. This is an optional feature you can declare for your application with the android:installLocation manifest attribute. If you do not declare this attribute, your application will be installed on the internal storage only and it cannot be moved to the external storage.
