Xposed Installer 3.1.1 APK Download by Rovo89

I have uploaded a new official installer (version 3.1) in the first post.
This version is based on @DVDandroid's fork. Special thanks to him and the other contributors for their work!

Features:
Material Design
Download the correct framework ZIP for your architecture/Android version
Install/uninstall Xposed directly from the app, no custom recovery required (but obviously you must still make sure that you can reflash your ROM in case something goes wrong!)
Many changes under the hood for better stability, compatiblity and code quality

Note that this version is not on repo.xposed.info for the same reason 3.0 wasn't there: It would show an update notification to all users, including those who are still on ICS/JB/KK, for which I don't have framework ZIPs (yet).
Unfortunately, working on the installer required much more effort and time than I had expected. Therefore, no official systemless for now. Instead, I'll target Nougat next.

About Xposed Installer 3.1.1

From version 3.1:

This is the installer for the Xposed framework, which is a requirement for all modules.

Xposed is a framework for modules that can change the behavior of the system and apps without touching any APKs. That's great because it means that modules can work for different versions and even ROMs without any changes (as long as the original code was not changed too much). It's also easy to undo. As all changes are done in the memory, you just need to deactivate the module and reboot to get your original system back. There are many other advantages, but here is just one more: Multiple modules can do changes to the same part of the system or app. With modified APKs, you to decide for one. No way to combine them, unless the author builds multiple APKs with different combinations.
