When you start the app the sensor must be instantiated once. It is not possible to change the site name or the application name after this call.

From this point on, the method getInstance must be used .

Info

In the library an adapter for class MPMoviePlayerController AVPlayerViewController from the MediaPlayer.framework AVKit ramework is settled.

The source code for this implementation can be found in Appendix A and in the library.

The following code block shows an example for the use of the library.

...

If the application is closed, the method unload can be called. This call sends the current state of the measurements to the measuring system and then terminates all measurements. This method is automatically called by the library, when the application goes into the background.
