android - OnCameraChangeListener() is deprecated

Question

Today, looking back at my old code, I've found out that OnCameraChangeListener() is now deprecated.

I'm finding difficult to understand how to fix this piece of code of mine:

mGoogleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
    @Override
    public void onCameraChange(CameraPosition cameraPosition) {
        // Cleaning all the markers.
        if (mGoogleMap != null) {
            mGoogleMap.clear();
        }

        mPosition = cameraPosition.target;
        mZoom = cameraPosition.zoom;

        if (mTimerIsRunning) {
            mDragTimer.cancel();
        }

        mDragTimer.start();
        mTimerIsRunning = true;
    }
});

The new listener (aka OnCameraMoveListener()) method onCameraMove() doesn't have a CameraPosition cameraPosition input variable, so I'm pretty lost: is there a way to recycle my old code?

Here are some references.

In play-services-maps 9.4.0 version of the API, They replaced GoogleMap.OnCameraChangeListener() with three camera listeners :

• GoogleMap.OnCameraMoveStartedListener
• GoogleMap.OnCameraMoveListener
• GoogleMap.OnCameraIdleListener

Based on your code, I think you need to use GoogleMap.OnCameraIdleListener and GoogleMap.OnCameraMoveStartedListener like this:

mGoogleMap.setOnCameraMoveStartedListener(new GoogleMap.OnCameraMoveStartedListener() {
            @Override
            public void onCameraMoveStarted(int i) {
                mDragTimer.start();
                mTimerIsRunning = true;
            }
        });

        mGoogleMap.setOnCameraIdleListener(new GoogleMap.OnCameraIdleListener() {
            @Override
            public void onCameraIdle() {
                // Cleaning all the markers.
                if (mGoogleMap != null) {
                    mGoogleMap.clear();
                }

                mPosition = mGoogleMap.getCameraPosition().target;
                mZoom = mGoogleMap.getCameraPosition().zoom;

                if (mTimerIsRunning) {
                    mDragTimer.cancel();
                }

            }
        });
