I have tried to create it as like below:- (It worked for me, hope the same for you as well)

```auto
protected void ZoomOut() {
    Log.e("Camera", "-- ZOOM OUT --");

    if (goCoderCameraView == null) return;

    if (currentZoomLevel > 0) {
        currentZoomLevel--;

        android.hardware.Camera.Parameters params = goCoderCameraView.getCamera().getPlatformDevice().getParameters();
        params.setZoom(currentZoomLevel);
        goCoderCameraView.getCamera().getPlatformDevice().setParameters(params);
    }
}	

```

```auto
// Add this line after you have initialised Wowza Services.

int currentZoomLevel = goCoderCameraView.getCamera().getPlatformDevice().getParameters().getZoom();

```
