Android application has stopped unexpectedly

Question

I try to launch my Android application on my phone (Sony Ericsson Xperia Neo). It launches normally, but when I try to open it, I see a message saying so sorry, you application has stopped unexpectedly, please try again and the button force close. Also the size of the installed application is only 820KB, though it has to be something like 8-10MB. btw, my application runs fine on tablets, problems only on phone. Any help ? thanks.

Here it's logcat output

Answer 1

The error refers to smallestScreenWidthDp which is something introduced in Android 3.2. You say that your phone is running Android 2.3.4 so you are calling some kind of code or configured something in your Manifest file that is causing the error.
