App cannot start at all in Android 2.2 (Froyo)

Question

My app has been running okay until the recent Froyo update. After installing the Android 2.2 SDK, I can compile my code without any errors. However, when I run it, it just force closes:

Here's the log:

</application>

The main startup class is com.handyapps.easymoney.EasyMoney. I placed a breakpoint at the start of the onCreate() method but I discovered it didn't even reach there. Somehow, the application just couldn't be loaded in Android 2.2... but it works perfectly fine for all the previous Android versions. Been trying to find the cause for the past 2 days but am totally stumped!!

Answer 1

From ClassCastException:

Thrown when a program attempts to cast a an object to a type with which it is not compatible.

I would go through the code and check the casts I am doing.

Answer 2

Guys, I've found the solution! Just need to remove the android:name attribute from the application tag in the manifest... but the compiler should have given a warning or error.
