NoClassDefFoundError Landroid/arch/lifecycle/LifecycleDispatcher

Question

I want to try out the new lifecycle stuff from google (https://developer.android.com/arch) but getting a crash on app open. All I have done is add the dependencies. Is anyone else having this problem?

Do you use Proguard? If so, try to turn it off:

debug {
    minifyEnabled false
    useProguard false
}

Or you can add custom rule to your Proguard config:

-keep class android.arch.** { *; }
