android - ClassNotFoundException on AndroidAnnotations generated classes since update to ADT 22

Question

This project worked wonders before updating to ADT22. I already lost a day because of not knowing I had to download build tools, and I'm afraid I'm going to loose another one because of this.

When I try to build the same code that was working two days ago, I get this exception:

com.cidaut.blueparking fatal error : Unable to instantiate activity 
    ComponentInfo{com.cidaut.blueparking/com.cidaut.blueparking.SplashScreen_}:

I actually find it weird that it is trying to find the class on the APK file, but whatever. Is there any solution to this?

By the way, my classpath includes the source folder where AndroidAnnotations generates the code, so that's not the issue.

Here's my Order and Export window

AndroidAnnotations class generation error log

EDIT: Now it is working

The procedure I followed was this:

1. Clean and rebuild everything
2. Check everything on the Order and Export tab of every project (both the main project and the libraries)
3. Clean and rebuild everything again

It works now. I can't believe I have lost almost 12 hours because of this...

Answer 1

Go to the "Order And Export" tab of "Configure Build Path" and click the check mark next to all of your required libraries
