我曾使用 phonegap 编写一个应用程序，该应用程序试图从 android 2.3.3 环境中的 java 脚本调用 java 函数。

我的问题是应用程序显示警报消息然后崩溃并在下面提示错误消息

任何人都可以就这个问题提供帮助/建议吗？

下面是代码 

 MainActivity.java

        import org.apache.cordova.*;

        import android.os.Bundle;
        import android.app.Activity;
        import android.view.Menu;
        import android.view.MenuItem;
        import android.support.v4.app.NavUtils;

        public class MainActivity extends DroidGap {
            private MyClass mc;

            @Override
            public void onCreate(Bundle savedInstanceState) {       

                super.onCreate(savedInstanceState);
                super.init(); 
                mc = new MyClass(this, appView);
                appView.addJavascriptInterface(mc, "MyCls");       
                super.loadUrl("file:///android_asset/www/5.html");
            }  

        }


    MyClass.java

        import org.apache.cordova.DroidGap;

        import android.content.Context;
        import android.telephony.TelephonyManager;
        import android.webkit.WebView;

        public class MyClass {
              private WebView mAppView;
              private DroidGap mGap;

              public MyClass(DroidGap gap, WebView view)
              {
                mAppView = view;
                mGap = gap;
                System.out.println("jjjjj");
              }

              public String getTelephoneNumber(){
                  return "i am android";
              }
            }

已经发现了。这个问题只发生在安卓模拟器上。它在带有 android 2.3.4 和 4.0.3 的设备上运行良好。
