**private boolean serverResponse() {
    int status=0;
    try {

        URI uri = new URI("http://www.google.com");     
        HttpClient client = new DefaultHttpClient();
        HttpGet httpGet=new HttpGet(uri);


        HttpResponse response = client.execute(httpGet);
        status=response.getStatusLine().getStatusCode();


        if(status==200)
            return true;

    } catch (Exception e1) {

        Toast.makeText(getApplicationContext(), "Not Connecting to URI and status"+status , Toast.LENGTH_SHORT).show();

    }
    return false;
}**

上面的代码在模拟器中工作正常。不在真实设备中。由于未连接URI，因此会捕获块。（实际设备中的Internet连接已启动）

应用程序在模拟器中连接到Internet而不是在真实设备中
