Activity needs to be set if initial lifecycle state is resumed

Hello I am trying to integrate react-native application inside inside my native android. I Follow steps give following links

https://facebook.github.io/react-native/docs/integration-with-existing-apps https://medium.com/mindorks/react-native-integration-with-existing-app-f2757c2e672d

Here is my react activity code

super.onCreate(savedInstanceState);
mReactRootView = new ReactRootView(this);
mReactInstanceManager = ReactInstanceManager.
        builder()
        .setApplication(getApplication())
        .setBundleAssetName("index.android.bundle")
        .setJSMainModulePath("index.android")
        .addPackage(new MainReactPackage())
        .setUseDeveloperSupport(BuildConfig.DEBUG)
        .setInitialLifecycleState(LifecycleState.RESUMED)
        .build();
mReactRootView.startReactApplication(mReactInstanceManager, "AwesomeProject", null);
setContentView(mReactRootView);

But I am getting following error when my react activity get launched

You can fix this in two ways. Either set the activity:

mReactInstanceManager = ReactInstanceManager.builder()
    .setApplication(getApplication())
    .setCurrentActivity(this) // <== *** HERE ***
    .setBundleAssetName("index.android.bundle")
    .setJSMainModulePath("index.android")
    .addPackage(new MainReactPackage())
    .setUseDeveloperSupport(BuildConfig.DEBUG)
    .setInitialLifecycleState(LifecycleState.RESUMED)
    .build();

...or change the initial life cycle state to something other than LifecycleState.RESUMED:

mReactInstanceManager = ReactInstanceManager.builder()
    .setApplication(getApplication())
    .setBundleAssetName("index.android.bundle")
    .setJSMainModulePath("index.android")
    .addPackage(new MainReactPackage())
    .setUseDeveloperSupport(BuildConfig.DEBUG)
    .setInitialLifecycleState(LifecycleState.BEFORE_CREATE) // <== *** HERE ***
    .build();
