Android Question Tablet Layout problem

I wrote an app using a 5" screen phone. Now that I used the UI cloud to see how it looks on other devices, the layout screen is the same but some of the labels and edittext boxes are cut in half. Does anyone have a solution for this problem?

Also when I upload the APK file to the GooglePlay store i get the message that I should design my app for Tablets as well as phones.

Thanks in advance for the help.
