Implementing native android .aar file or .aidl in Nativescript throws native calss object without access to methods

先從外掛程式的 index.js 和 App_Resources/Android/libs 下的 .aar 放置位置開始，然後重現 issue 中的 native object 和 printerInit 日誌。檢查 Android runtime 如何公開已封裝的 Java class；當 SDK 方法可用且能夠在不出現 TypeError 的情況下呼叫時，即表示完成。

  Describe the bug

I have an Android SDk done with java whic I already converted to .aar file. I created a plugin and placed the aar file in App_Resources/Android/libs directory. In my index.js file, I have this

var intent = new android.content.Intent(application.android.foregroundActivity, com.iposprinter.printertestdemo.IPosPrinterTestDemo.class)
intent.setFlags(android.content.Intent.FLAG_ACTIVITY_NEW_TASK);
application.android.foregroundActivity.startActivity(intent);

This cause the sdk to display.

Doing this

var iposprinter=new com.iposprinter.printertestdemo.IPosPrinterTestDemo()
console.log(iposprinter) //outputs com.iposprinter.printertestdemo.IPosPrinterTestDemo@682890e
while this `console.log(iposprinter.printerInit) outputs undefined`

while this

`console.log(iposprinter.printerInit) outputs undefined`
console.log(iposprinter.printerInit()) outputs undefined
TypeError: iposprinter.printerInit is not a function

How do I call methods from this package?
