When you develop an app, there are a few things you can do to make it use network and power resources as efficiently as possible. And by doing so, you will also provide a clearly enhanced user experience. Håkan Jonson, a research engineer at Sony Mobile’s Technology office, created a tutorial a while back that will help you develop energy and network efficient apps. In his tutorial, you will find useful and hands-on tips, as well as code examples that will help you improve your app.
Today, we’re introducing the Xperia™ SP & Xperia™ L, two new models joining the Xperia™ range of premium smartphones. Xperia™ SP comes with a 1.7 GHz Qualcomm® Snapdragon™ S4 Plus dual core processor with the Adreno 320 GPU, 1 GB RAM, 4.6” HD Reality Display with Mobile BRAVIA® Engine 2, Android™ 4.1 (Jelly Bean), LTE, NFC, GLONASS, Battery STAMINA mode, and an 8MP camera with HDR for picture. Xperia™ L offers a 1 GHz Qualcomm® Snapdragon™ S4 Plus dual core processor, 1 GB RAM, 4.3” FWVGA display, Android™ 4.1 (Jelly Bean), NFC, Battery STAMINA mode, and an 8MP camera with HDR for picture and movie. The new Xperia™ SP and Xperia™ L will both be available from Q2 2013. Get more specs after the jump.
One of the awesome features you’ll find in the recently announced Sony Xperia Z is its 5” screen, which boasts a display density of 440 dpi, and falls into a new class of screen called xxhdpi. With more and more xxhdpi devices coming out, it’s important to make sure you have configured your app’s Android manifest not to exclude such high density screens. Otherwise you might find that your app isn’t showing up on Google Play™ when searched from these devices. Read on to learn what to do, and what not to do, to support xxhdpi screens.
Today, we’ve officially announced the global availability of Xperia™ Tablet Z, the world’s slimmest LTE tablet. This premium HD tablet sets new standards for tablet thinness, weight, and water-resistance. Measuring only 6.9mm and weighing under 500g, it’s the thinnest and lightest LTE tablet available. And it has the highest levels of water resistance (IP55 & IP57) ever delivered in a tablet. Xperia™ Tablet Z is also the first tablet to run on the Qualcomm® quad-core Snapdragon™ S4 Pro processor. Read on to get the full specs for Xperia™ Tablet Z.
As our smartphones become more powerful, they can do more advanced things that previously required a high-end PC. One way to make use of the robust processing power of your smartphone is Computer Vision, which basically lets you use the powerful CPU in modern smartphones to interpret the images captured through the camera. The best approach to using Computer Vision on Android is through library called OpenCV. Check out our new Open CV tutorial where Erik Hellman, research engineer at Sony, explains more.
As our smartphones become more powerful, we can do more advanced things that previously required a high-end PC. One way to make use of the robust processing power of your smartphone is Computer Vision – the ability for a device to acquire, process, analyse and understand images the same way images are perceived by human eyes. Basically, we can use the powerful CPU in modern smartphones to interpret the images captured through the camera. Examples of use cases are face detection and recognition or simple post-processing of photographs. The best approach to using Computer Vision on Android is through library called OpenCV.

Developer World is Sony’s main hub for Android™ developers, and in addition to handy tutorials and the latest technical news, don’t forget that we also have valuable developer tools to help you in many stages of app development, whether you’re working on a Sony tablet, smartphone, or a mobile accessory. The BacklogTool, ChkBugReport, and XAppDbg are also open sourced, so you can modify these tools to suit your own development needs. Read further to get a quick summary of some of the tools available.
App developers, have you ever wished that you wouldn’t have to rebuild and run your application to try out every small change you’re making? Sony’s XAppDbg tool (eXtra Application Debugging tool) lets you try out different parameters without the need to rebuild the code for every change. And it’s open source! Read on as Pál Szász, who developed the tool, explains more!
The latest version of AppXplore – version 2.5 – is now available for download on Google Play. AppXplore is a free analysis tool that lists all the apps on your Android device, and gives you detailed information for each, including permissions used, Android™ versions supported, libraries shared, and much more. AppXplore is especially useful for seeing how much memory an app is using, and if the file is movable to the SD card. Likewise, developers can use AppXplore for QA purposes, to make sure their apps are showing the proper permissions in the manifest file. Read on to learn more about the latest features of AppXplore 2.5.
A number of Xperia™ devices have an IR remote sensor, allowing you to use the IR remote API to develop an app that sends infrared signals. The Xperia devices which include an IR sensor also come with a universal infrared (IR) remote control app that can control devices such as HDTVs, DVD players, audio systems, and cable boxes. This is because the remote control app has a number of stored device profiles within the API.
