Great for a first time application! How did you implement a picture as a background though? A problem however was that if you click calculate love and try to read the small text, it will somewhat blend into the background, it should be a little bit more readable! Putting that aside, good work!

I thought I'd give your application a try, however when trying to install the application I get the following error: "Parse Error: There is a problem parsing the package."

edit:
Hi again, I tried downloading your application from my computer and install it by doing "adb install lovecalculator.apk" (I renamed it), when installing, this appears:
"file 'lovecalculator.apk' does not contain AndroidManifest.xml", there's your problem :)
