我正在尝试在Android的Java应用程序中使用Mozilla Rhino来评估一些JavaScript.我正在使用Eclipse + ADT插件.

首先,我尝试从Mozilla的网站下载Rhino .jar文件,并将其作为Eclipse中的库添加到项目中.Eclipse认识到它很好并编译了应用程序.但是,在运行它时,我在调用时会遇到异常Context.evaluateReader()(请参阅下面的堆栈跟踪).

然后我尝试将Rhino源代码添加为Eclipse中的单独Android项目,将其标记为库并在我的项目中引用它,这足以让Eclipse将其编译,但导致了同样的错误.

这是我得到的堆栈跟踪(java.lang.UnsupportedOperationException: can't load this type of class file)

 public void bEqual(View v) throws ScriptException {

       ScriptEngineManager mgr = new ScriptEngineManager();
       ScriptEngine engine = mgr.getEngineByName("JavaScript");
        String value = inputText.getText().toString();
        Toast.makeText(this,value,Toast.LENGTH_LONG).show();
        try{
            result = (double)engine.eval(value);
            Toast.makeText(this,String.format("%f",result),Toast.LENGTH_SHORT).show();
        }catch(Exception e){
            Toast.makeText(this,"Exception Raised",Toast.LENGTH_SHORT).show();
        }

    }

这其中有什么问题吗？执行此操作时应用程序正在退出。它没有显示任何错误，但应用程序正在关闭
