Unity calls Android Native method (one) to get Android system volume

Learn Lei Feng, a good example, the next tutorial in this series, will be through unity to achieve some of the common features of the Android side,

It is important not to refer to the jar package or the AAR package in the Asset/plugins/android directory.
