NoClassDefFoundError When Using Dagger 2 After Switching to Android Studio 2.0

Before upgrading to Android Studio 2.0 I could use Dagger 2 no problem. Now I am getting a NoClassDefFoundError This has shut me down for more than a day and I'm reaching out for some help.

It seems as though Gradle cannot my AppModule class even though it is pretty clear that it is in my project. I have even included set multiDexEnabled true even though my project is only a few files.

Everything I can find online says that you can click your libraries to be imported. Android Studio has no such luxury.

Any help would be greatly appreciated and you will have my undying loyalty.

Your Application doesn't extend from MultiDexApplication, nor does it do

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

And you should disable Instant Run.

I had a very similar issue and resolved it by doing pretty usual things in Android Studio. You basically need to

Invalidate Caches and then Clean Project

You know, Dagger2 generates a lot of code at compile time and sometimes things can mess up, especially if you are using Instant Run, provided by Android Studio 2.0
