android

I am writing an android application using Eclipse as IDE, when I got a force close error on the emulator and on my phone. I just changed the layout and the strings.xml and I have no errors shown in eclipse, still it says "force close" when I try to open the application on the eclipse emulator or smartphone. This is my layout , main.xml.

This seems to have occured because there's a missing class in corresponding location

heres an excerpt from your log

 at dalvik.system.NativeStart.main(Native Method)
10-29 13:11:10.122: E/AndroidRuntime(275): Caused by: java.lang.ClassNotFoundException: android.androcrane.htlottakring.Androcrane in loader dalvik.system.PathClassLoader[/data/app/android.androcrane.htlottakring-2.apk]

so make sure this class is located there.to avoid this
