I have tested this app on the Android emulators, phones, tablets, and Google TV. Its works. When I published it Google Play, the app is not visible. Below is the manifest
Since you've waited a sufficient amount of time and it should appear, you can try checking your APK to see what default permissions and features your app requires using aapt:
$ aapt d badging your.apk
Make sure that what is listed for features is not filtering your device. You can mostly do this on Google Play too, but I have seen a few differences where Google Play will show that it is available for older devices, but it actually will not install.
Also, as suggested by @ricvieira, you should do a query in a web browser to see if your app shows up at all.
