How to make (ARM7 & x86) apk file compatible in any android devices?

add crosswalk plugin…
if you build your app you will get two apk files.

yeah but, the 1 of the 2 apk files are not compatible of some of the android devices

but that should be done by the appstore --> it should provide the working one for your phone if it is available
