MultiDex NoClassDefFound error

I have converted my application into MultiDex to bear with 64k dex limit. Now it looks like this:

public class App extends MultiDexApplication {

private AppWrapper instance;

@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(base);
}

@Override
public void onCreate() {
super.onCreate();

if (instance == null) {
instance = new AppWrapper(this);
}
}
}


I've pulled all the usual logic from App to
AppWidget
to make
MultiDex
work. And it works ok on other teammates' computers. But not with me. It keeps throwing
java.lang.NoClassDefFoundError
on application create:

I have the same Android Studio, gradle, sdk, jdk versions, same code. I've even tried to format hard drive and reinstall OS to make sure that environment is the same. What can be the cause of this strange problem?

This is my

Answer

Your AppWrapper class fails to load because the retrofit.ErrorHandler interface is not included in main dex file.

How do you calculate which classes to put in your main-dex-list file?
There's a script that can generate it for you. I wrote a blogpost that shows how to use it.

Update (10/31/2014):
Gradle plugin v0.14.0 now does it automatically. See my answer here.
