I finally created an official version for(aka SDK22). You can download it asfrom the first post.This version is not directly based on @ romracer 's port, however there aren't many differences. He had merged AOSP 5.1 into the Xposed codebase, I did it the other way around and used this opportunity to reorder and combine the commits. So it's a little bit cleaned up now, which will hopefully make it easier to port these changes to future Android versions. I have also cherry-picked two of his changes that weren't in the offical version yet: A fix for a special case in resource handling on 64-bit and compression of the backup Xposed creates during its installation. Many thanks to @ romracer for providing the unofficial version - this gave me the chance to fix and improve many things (which were in turn merged by him and others).That said, there are also a few new changes:- In error messages, the Android version is now display as well, e.g. "Wrong Android version: 5.1 / SDK22 ... This file is for: 5.0 / SDK21"- The files for Android 5.1 can now handle gzip-compressed odex files (*.odex.gz). Those files only exist on certain ROMs (e.g. CM) that merged a few commits proposed by Intel. These commits weren't accepted into AOSP because the way they're handling the compressed files has some flaws. With Xposed installed, these files will be unpacked on-the-fly and recompiled.The gzip support might also be interesting for ROMs where the /system partition is almost full. It should be possible to gzip some of the .odex filesinstalling Xposed in order to free up some space. This should work on any odexed 5.1 ROM, even if the Intel commits aren't included. However, this would be very experimental. Volunteers are welcome, but don't forget to create a backup.Finally, I have updated the uninstaller zips. They include a timestamp now, as new installer zips might require new uninstaller versions. You should always be able to uninstall older versions with the latest uninstaller though. v72 requires at least the uninstaller from today (20150831).
