我正在尝试在电话间隙中开发应用程序。它监视服务器作业。目前服务器不可用，所以我把我的系统作为服务器。我将项目文件放在安装服务器的同一目录中。我正试图在主要活动中访问我的文件。但它在我的模拟器上显示错误。错误标题为"不支持协议"。我在下面分享主活动文件和html文件。请看这些文件。主活动文件：
package com.example.productionmonitor;
import org.apache.cordova.DroidGap;
import android.os.Bundle;
import android.view.Menu;
public class MainActivity extends DroidGap{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
System.out.println("Here");
super.setIntegerProperty("loadUrlTimeoutValue",120000);
super.loadUrl("file////C:/Program Files/Elixir Technologies/Tango/tomcat/webapps/productionmanagerserver/Monitor app/productionMonitor.htm");
//super.loadUrl("file:///android_asset/www/productionMonitor.htm");
//super.loadUrl("C:///|Program Files/Elixir Technologies/TangotomcatwebappsproductionmanagerserverMonitor appproductionMonitor.htm");
//super.loadUrl("http:///localhost:8080/productionmanagerserver/productionMonitor.htm");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是我保存在位置(C:\Program Files\Elixir Technologies\Dango\tomcat\webapps\productionmanagerserver\Monitor-app\login.html(的html文件，我想访问该文件。

把文件放在windows机器上的哪个位置并不重要。无论是您的android设备还是Emulator都无法访问它们。如果你仔细想想，那就太可怕了。
你需要把你的开发机器变成一个合适的服务器，然后从模拟器中用特殊的ip地址10.0.2.2访问它，这是开发机器的环回。如果你在一台设备上进行测试，你需要访问开发机器的本地IP地址，假设你在同一个局域网上。
