OnCameraChangeListener() is deprecated

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();
                }

            }
        });
