科尔多瓦Android Volume Plugin问题

Question

我正在尝试使用此Cordova Android Volume Plugin在基于Cordova的android应用上添加触摸屏音量。但是我遇到[Image error for error] [2]错误，并且很可能是该平台的新手，我也缺乏如何在该平台上使用插件的知识。

在下面的代码中，我只想将android硬件设备的体积增加到 100使用以下功能，如插件中所述。但是我得到了错误

window.androidVolume.set(100, true, function()    // line 67 error 
                    {      console.log('Turned up volume'); 
                            }, 

                            function(e) { console.log(e); });



                  });
