             />
    </GridLayout>
</LinearLayout>

keep in mind I am a complete noob just trying to build an app for a project. I could really use help for this and for the future of my project. Thanks again sorry for the long post.

Looks like you may have duplicate activity_my.xml files. Make sure that only one file will be accessed by a given device. If you just want to target all devices with one layout. Simply put all layouts in res/layout/ and delete the deeper layout dirs.
