Android ==>应用程序开发？(Android ==> Application development?)

 
  我是iphone应用程序开发人员，所有iphone都有非常相似的操作系统，大小和一切都是一样的，所以我不需要为每个iphone创建特定的应用程序。 但是对于Android有不同的手机，不同的尺寸，那么我怎么可能知道我的应用程序工作，并在所有这些设备上看起来很好  
  我还没有自己的Android，但我使用模拟器完成了我的第一个应用程序。 您建议哪种Android手机进行测试？ 我是AT＆T用户，我使用iphone。 我可以简单地在新的Android中插入我的SIM卡，以便能够在设备上测试我的应用程序吗？  

 
 I am an iphone application developer, all iphones have very similar Operating systems, and the size and everything is the same, so I don't need to create applications specific for each iphone. But with android there are different phones, different sizes, So How can I possibly know that my app works, and looks fine on all these devices 
 I don't already own an android but I completed my first application using the simulator. Which android phone do u suggest for testing? I am an AT&T user and Iuse an iphone. Can I simply insert my sim-card in the new android to be able to test my app on the device?

 将MetricsServlet添加到它自己的ServletContextHandler中，并注册MetricsServlet.ContextListener的实现来修复它。  
   _server = new Server(_port);
    ResourceHandler resourceHandler = new ResourceHandler();
    resourceHandler.setDirectoriesListed(true);
    resourceHandler.setWelcomeFiles(new String[]{"index.html"});
    resourceHandler.setResourceBase(".");
    HandlerList handlers = new HandlerList();
    ServletContextHandler guiceHandler = new ServletContextHandler();

    ServletContextHandler metricsContextHandler = new ServletContextHandler();
    metricsContextHandler.setContextPath("/one/metrics");
    metricsContextHandler.addEventListener(new MyMetricsServletContextListener(_metricRegistry));
    metricsContextHandler.addServlet(MetricsServlet.class, "/registry");

    guiceHandler.setContextPath("/one/id");
    try {
        FilterHolder guiceFilter = new FilterHolder(_filter);
        guiceHandler.addFilter(guiceFilter, "/*", EnumSet.allOf(DispatcherType.class));
        handlers.setHandlers(new Handler[]{metricsContextHandler, guiceHandler, resourceHandler});
        _server.setHandler(handlers);
        _server.setDumpAfterStart(true);
        _server.start();
    }catch(Exception ex) {
        log.error("Error starting http server", ex);
        throw new RuntimeException(ex);
    }
 
 MetricsServlet.ContextListener实现（注册表通过guice绑定提供）：  
    private static class MyMetricsServletContextListener extends MetricsServlet.ContextListener {
    private MetricRegistry _metricRegistry;
    public MyMetricsServletContextListener(MetricRegistry metricRegistry) {
        _metricRegistry = metricRegistry;
    }
    @Override
    protected MetricRegistry getMetricRegistry() {
        return _metricRegistry;
    }
}

Adding the MetricsServlet to it's own ServletContextHandler, and registering an implementation of MetricsServlet.ContextListener fixed it.  
   _server = new Server(_port);
    ResourceHandler resourceHandler = new ResourceHandler();
    resourceHandler.setDirectoriesListed(true);
    resourceHandler.setWelcomeFiles(new String[]{"index.html"});
    resourceHandler.setResourceBase(".");
    HandlerList handlers = new HandlerList();
    ServletContextHandler guiceHandler = new ServletContextHandler();

    ServletContextHandler metricsContextHandler = new ServletContextHandler();
    metricsContextHandler.setContextPath("/one/metrics");
    metricsContextHandler.addEventListener(new MyMetricsServletContextListener(_metricRegistry));
    metricsContextHandler.addServlet(MetricsServlet.class, "/registry");

    guiceHandler.setContextPath("/one/id");
    try {
        FilterHolder guiceFilter = new FilterHolder(_filter);
        guiceHandler.addFilter(guiceFilter, "/*", EnumSet.allOf(DispatcherType.class));
        handlers.setHandlers(new Handler[]{metricsContextHandler, guiceHandler, resourceHandler});
        _server.setHandler(handlers);
        _server.setDumpAfterStart(true);
        _server.start();
    }catch(Exception ex) {
        log.error("Error starting http server", ex);
        throw new RuntimeException(ex);
    }
 
The MetricsServlet.ContextListener implementation (registry is provided via guice binding): 
    private static class MyMetricsServletContextListener extends MetricsServlet.ContextListener {
    private MetricRegistry _metricRegistry;
    public MyMetricsServletContextListener(MetricRegistry metricRegistry) {
        _metricRegistry = metricRegistry;
    }
    @Override
    protected MetricRegistry getMetricRegistry() {
        return _metricRegistry;
    }
}
