The battery life of smartphones and tablets is extremely important for many users, and in order to provide end users with good battery performance, device manufacturers have a joint responsibility together with all of you app developers. The power-save feature STAMINA mode, available on our latest Xperia™ devices including Xperia Z, is a clever way for us to improve the battery life for our users. And as an app developer, there are several things you can do to make your app more power efficient. Read on for five of our best tips, that will also ensure your app runs well with STAMINA mode turned on.
With Sony’s power management setting called Battery STAMINA Mode, you can extend the standby time of your Xperia™ device by more than four times. With Battery STAMINA Mode turned on, the background activities of most applications are reduced when you turn off the screen. Read more on how it works after the jump!
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.
The new Xperia Tablet Z and its smartphone equivalent, Xperia Z, are the latest Sony products that include Small Apps and IR remote sensor functionality. If you’re ready to start developing your own Small Apps or your own IR remote sensor-enabled apps, you’ll want to do so using the new Sony Add-on SDK. Read on for a quick look at how you can get your development started right away!
You’ve all been able to develop app extensions for SmartWatch and Smart Wireless Headset pro for a while with the old Smart Extension SDK, but now we have replaced this with the new Sony Add-on SDK. So far, hundreds of apps have been created or extended to work with these devices. Read on for a walkthrough of the most useful facts and tips, for those of you looking to develop an app for SmartWatch and Smart Wireless Headset pro with the Sony Add-on SDK (and learn more about the SmartWatch update being released today!).
UPDATE: The Music Infinite API is deprecated, and no longer supported in the Sony Add-on SDK. Do you have an app or service around music? Or maybe you run a music store app, an artist information site, an artist oriented app, a fan site or something similar? Then you can develop an app extension for “WALKMAN” music player, using the Music Infinite API available in the Sony Add-on SDK that was launched last week. In the “WALKMAN” music player app, the Infinite button can be used to access related information, content and services about the song or artist currently being played.
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.
A few weeks ago, we highlighted LTE coverage for Xperia smartphones to let you know which devices had LTE support and the regions which generally offered LTE service. Now, we’d like to share with you the next step in the evolution of LTE – making voice calls over LTE, which we’re currently demonstrating at Mobile World Congress. Voice over LTE (VoLTE) gives you telecom-grade voice functionality over IP while keeping the high speed data connection. Read on as Sony connectivity engineers, Daniel Lönnblad and Pär Olsson, share their VoLTE expertise.
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.
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.
