React 0.18 causes Module error - react-native

Question

I'm getting the following error when trying to get a Module working after updating to React Native 0.18:
com.lwansbrough.RCTCamera.RCTCameraViewManager cannot be cast to
com.facebook.react.uimanager.ViewGroupmanager
What causes this type of error, and how can it be resolved?
Here is the code for RCTCameraViewManager:
package com.lwansbrough.RCTCamera;
import android.support.annotation.Nullable;
import com.facebook.react.uimanager.*;
public class RCTCameraViewManager extends SimpleViewManager<RCTCameraView> {
private static final String REACT_CLASS = "RCTCameraView";
#Override
public String getName() {
return REACT_CLASS;
}
#Override
public RCTCameraView createViewInstance(ThemedReactContext context) {
return new RCTCameraView(context);
}
#ReactProp(name = "aspect")
public void setAspect(RCTCameraView view, int aspect) {
view.setAspect(aspect);
}
#ReactProp(name = "captureMode")
public void setCaptureMode(RCTCameraView view, int captureMode) {
// TODO - implement video mode
}
#ReactProp(name = "captureTarget")
public void setCaptureTarget(RCTCameraView view, int captureTarget) {
// No reason to handle this props value here since it's passed again to the RCTCameraModule capture method
}
#ReactProp(name = "type")
public void setType(RCTCameraView view, int type) {
view.setCameraType(type);
}
#ReactProp(name = "torchMode")
public void setTorchMode(RCTCameraView view, int torchMode) {
view.setTorchMode(torchMode);
}
#ReactProp(name = "flashMode")
public void setFlashMode(RCTCameraView view, int flashMode) {
view.setFlashMode(flashMode);
}
#ReactProp(name = "orientation")
public void setOrientation(RCTCameraView view, int orientation) {
view.setOrientation(orientation);
}
#ReactProp(name = "captureAudio")
public void setCaptureAudio(RCTCameraView view, boolean captureAudio) {
// TODO - implement video mode
}
}

I also got this error, my solution was to change the
public class RCTCameraViewManager extends SimpleViewManager<RCTCameraView>
to
public class RCTCameraViewManager extends ViewGroupManager<RCTCameraView>
