Can't convert to dimension: type=0x1 when running app on Android 4.1

Question

I recently started to use genymotion instead of classic Android virtual device, but I have some issues with it.. When I try to run my app I got this error.

Always look at the API Level for an attribute:

android:layout_alignParentEnd was added in API level 17
