WARN on Android app load

[HebertGB]

WARN new NativeEventEmitter() was called with a non-null argument without the required addListener method.
WARN new NativeEventEmitter() was called with a non-null argument without the required removeListeners method.

To fix it:

edit file /android/src/main/java/com/reactnativesmartconfigswjava/SmarconfigSwjavaModule.java

add this:

// Required for rn built in EventEmitter Calls.
@ReactMethod
public void addListener(String eventName) {
}

@ReactMethod
public void removeListeners(Integer count) {
}

That's solved my issue, like suggest here
