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.

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.
If you’re currently working on an app where image scaling is needed, such as when you’re developing a SmartWatch extension for your application, don’t forget that we have a handy tutorial to explain how to get images scaled correctly. Andreas Agvard, a Senior Software Engineer at Sony, has created an image scaling code example that you can download, compile, and run. Read more after the jump.
