How to Port Sony Small Apps and Task Switcher to CM10.1
If own a Sony Xperia device and have switched out your ROM for an AOSP-derived firmware such as CyanogenMod, you may miss a few OEM-provided pieces of software from time to time. Some of the interesting value-added software provided by Sony include their “small apps,” as well as their upgraded task switcher.
Thankfully, XDA Senior Member lukakas has created a guide to help you port these Sony-specific additions to CyanogenMod 10.1 (and perhaps any ROM based on Android 4.2.2). More specifically, the guide allows you to bring the Sony Xperia Z-specific versions of those addons.
The guide is extremely well written, and even features a helpful YouTube video that shows some of these additions in action. The guide walks you through the process of decompiling and modifying android.policy.jar, framework.jar, framework-res.apk, and SystemUI.apk. All of the modifications as well as what to do afterward are clearly outlined and color coded.
Head over to the tutorial thread to get started. Kudos to lukaskas for the well written and easy-to-follow instructions.
