Icons are some of the most commonly themed elements of the Android UI, and there is certainly no shortage of great looking icon packs available for download. The downside, however, is that some of these packs are designed to be used with specific launchers. And if you are anything like I am, quite attached to your launcher of choice and unwilling to switch, this can be frustrating. While there are ways of making use of any icons on any launcher, they can often be tedious if the compatibility isn’t there to begin with. With a little help from the Xposed Framework though, that process can be simplified considerably.
XDA Senior Member ruqqq developed Icon Themer, an Xposed module that allows you to use icon packs designed for specific launchers on a variety of other popular launchers quickly and easily. The module also offers a more consistent theming experience than other methods, as the icons are applied system-wide instead of simply on your home screen. The mod supports both paid and free icon packs available via the Play Store, and it will work on both odexed and deodexed ROMs. You need to be running Android 4.0+ with root access and of course have the Xposed Framework installed. After that, you can simply download the icon pack of your choice and apply it through Icon Themer.
