The Xposed framework was developed by German Android developer Rob, aka rovo89, along with the additional modules for adding new features into Android. The only requirement is that the Android device must be rooted and based at least on version 4.x.
The Xposed framework provides developers access to system functions, so that tools – “modules” in the jargon of Xposed – can add code in certain places. Already more than 200 modules are available for Xposed, which significantly extend Android.
The Xposed framework is extremely popular in the Android community. Users who shy away from installing a Custom Rom, can customise their device with this. Those who place an emphasis on data protection can reduce the data consumption of apps to zero with the module Xprivacy.
