Xposed frame work cannot be installed
I'm using moto X under att contract, now the android version is 4.4.2
I recently rooted my device with the towel pie root, and it works fine on my phone
But when I tried to use the Xposed, here comes the problem. The xposed apk can be installed perfectly, but when I go in there and tried to install the frame work, it shows as the picture below
Please help me find out why, many thanks!
