我正在尝试将一些字符串发送到一些php文件，并获取JSON变量。现在，我被困在将字符串发送到我的php文件中，我尝试了许多教程的许多组合，所有这些组合都压在了：

httpclient.execute(httppost);

我真的不知道为什么。PS我在manifest.xml文件中授予了INTERNET权限。这是我的代码，除了我之外，其他人都可以使用。

public void send()
{

    String  msg = "Some message text";


    if(msg.length()>0) {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://localhost:8888/file.php");

        try {
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("id", "01"));
            nameValuePairs.add(new BasicNameValuePair("message", msg));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            httpclient.execute(httppost);// THE APP CRASH HERE!!!
            Toast.makeText(getBaseContext(),"Sent",Toast.LENGTH_SHORT).show();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    } else {
        Toast.makeText(getBaseContext(),"All fields are required", Toast.LENGTH_SHORT).show();
    }
}

目前，我只想通过发送过程（接下来将处理JSON问题）。

谢谢你们。

这是LogCat：
