I have downloaded "de.robv.android.xposed.installer_v25_3_6cbbc. apk" and "de.robv.android.xposed.installer_v25_3_6cbbc-1.apk"
I get the same problem with either. The package installs but will not go active. I can get into the app but there is a red warning that the latest version is not active. Click on the Framework button and try the install/update button. The app stops responding and I get a wait or close pop-up. Same when I try the "soft reboot" and the "reboot" button. I have powered off after the install to no affect. It shows two items under Versions "app_process" with a red dash under the active column and a 47 under the bundled column and "XposedBridge.jar" with a 42 under the active and bundled columns.
Are there any other compatibility issues other than ART that I am not aware of? Anything else I should be checking on?
