Nexus 7 Support for Android Application Manifest Assembly

I have an Android Application that has the AndroidManifest.xml listed below. After uploading to Google Play, the Nexus 7 is listed as an UNSUPPORTED device and I am trying to figure out why. Of course Google Play doesn't tell you why or what permission or use of the manifest is restricting it from being supported. Any ideas of which part of the code below is causing the Nexus 7 to be listed as unsupported?
