There are a plethora of tools out there to help themers theme. The most popular of which include ways to compile and decompile APK files and free apps like Gimp to help the actual theming process. Even so, creating a good theme takes a lot of time and effort. However, for those who have phones from the Sony Xperia 2011 lineup, there’s an application that helps create themes for you.
XDA Forum Member Snndev has released an application that themes ROMs for most Sony Xperia 2011 devices. It is pretty simple to use, as users just download and extract the application. From there it’s ready to use. The way it works is it detects your XTF path to determine which Xperia device you have. From there, it creates a theme. Simply install the theme and you’re ready to go. The current features include:
Generate Flashable Zip
Preview Before Compile
Save XTF Path location
Compatible with other models
There are some drawbacks to XThemer. It doesn’t support custom themes, but rather has themes built into the application that users choose and assemble. While this may seem restrictive, anyone who simply wants a color change from the stock ROM will find this application to be all they really need.
