alright go to Apache httpd.conf (located in Apache folder): and search for
好的，转到 Apache httpd.conf（位于 Apache 文件夹中）：并搜索
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
and check if the second line is Deny, if it is then change it to:
并检查第二行是否为拒绝，如果是，则将其更改为：
Allow from all
then restart the Appache server, and tell me the feadback.
然后重新启动 Appache 服务器，并告诉我反馈。

Mikehelped me a lot on this issue. So here my steps to avoid this Connection refused.
迈克在这个问题上帮了我很多。所以这里我的步骤是避免这种连接被拒绝。
1) Add if to test Android SDK. It seems that in new versions you have to explicity allow the connection to be open in a different thread:
1) 添加if来测试Android SDK。似乎在新版本中，您必须明确允许在不同线程中打开连接：
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
System.out.println("*** My thread is now configured to allow connection");
}
...
...
2) Add an exception for your port:
2）为您的端口添加一个例外：
in your case allow inbound connection for port 8080
在您的情况下，允许端口的入站连接 8080
3) test your connection by browsing the desired url locally
3) 通过在本地浏览所需的 url 来测试您的连接
use your browser and try to visit http://10.0.2.2:8080locally
使用您的浏览器并尝试在http://10.0.2.2:8080本地访问
4) Add in your manifest file a permission for internet:
4）在您的清单文件中添加互联网权限：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.yourapp"
android:versionCode="1"
android:versionName="1.1" >
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.INTERNET"/>
I am using Wamp, and its apache is listening to servername localhost and port 8080 (allow from all in httpd.conf).
我正在使用 Wamp，它的 apache 正在侦听服务器名称 localhost 和端口 8080（允许来自 httpd.conf 中的所有内容）。
My local IP is something similar to 192.168.0.XXX/folder/my-page-here
我的本地 IP 类似于 192.168.0.XXX/folder/my-page-here

I fix this problem by writing my IP address from cmd -> ipconfigin the url :
我通过cmd -> ipconfig在 url 中写入我的 IP 地址来解决这个问题：
HttpPost httppost = new HttpPost( "http://192.168.x.x/mylibman/data.php" );

if your SDK version is less then 9 then add above code for SDK version them some changes in Apache update httpd.conf as line deny from all..replace that sentence Allow from all and restart services of WAMP server then use 10.0.2.2address or 10.0.2.2:8080port no and include permission line in android AndroidManifest file
如果您的 SDK 版本小于 9，则为 SDK 版本添加上面的代码，它们在 Apache 更新 httpd.conf 中进行一些更改，作为 line deny from all.. 替换那句话 Allow from all 并重新启动 WAMP 服务器的服务，然后使用10.0.2.2地址或10.0.2.2:8080端口号和在 android AndroidManifest 文件中包含权限行
<uses-permission
android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE">
</uses-permission>
