RuntimeException:ClassNotFoundException android.arch.lifecycle.ProcessLifecycleOwnerInitializer

Question

I am getting this error only on Android SDK < 5.0. So 4.0, 4.2, 4.3 ect. Anything running Android 5.0+ works flawlessly. Any ideas? Crashes on launch.

Following this guide for setup -> https://developer.android.com/topic/libraries/architecture/adding-components.html

App.java

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

    ProcessLifecycleOwner.get().getLifecycle().addObserver(new AppLifecycleListener(this));
    registerActivityLifecycleCallbacks(this);
}

AppLifecycleListener.java

public class AppLifecycleListener implements LifecycleObserver {
private App app;

public AppLifecycleListener(App app)
{
    this.app = app;
}

@OnLifecycleEvent(Lifecycle.Event.ON_START)
public void onMoveToForeground() {
    if (app.getCurrentActivity() instanceof BaseActivity)
    {
        BaseActivity baseActivity = (BaseActivity) app.getCurrentActivity();
        baseActivity.runIsAPIVersionCheck();
        baseActivity.fetchObjectsWithHUD(false);
    }
}

@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
public void onMoveToBackground() {}

}

This ended up being a multdex issue. I followed the docs here -> https://developer.android.com/studio/build/multidex.html#mdex-gradle and it works great now!

Gradle:

implementation 'com.android.support:multidex:1.0.3'

App.java:

public class App extends Application implements Application.ActivityLifecycleCallbacks {

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