【问题描述】：

我正在使用来自http://jsonrpcphp.org/?page=example&lang=en 的 JSON-RPC PHP 创建 php jsonrpc 作为服务器

和 android-json-rpc 作为 android http://code.google.com/p/android-json-rpc/ 的客户端

我的服务器没问题，我可以从 php 调用它，但是当我从 android 调用它时，它给了我系统错误，我无法解决它，任何人都可以帮忙吗？

我的安卓代码是

        JSONRPCClient clientrpc = JSONRPCClient.create("http://192.168.1.102/server.php",JSONRPCParams.Versions.VERSION_2);
      clientrpc.setConnectionTimeout(2000);

      clientrpc.setSoTimeout(2000);
        try 
        
          JSONArray stringdata = clientrpc.callJSONArray("login","demo","123456");

          try 
            Toast.makeText(getApplicationContext(),
                        stringdata.getString(1), Toast.LENGTH_SHORT)
                        .show();
         catch (JSONException e) 
            // TODO Auto-generated catch block
            //  e.printStackTrace();
            Toast.makeText(getApplicationContext(),
                    "ERROR ON CHECKLOGIN", Toast.LENGTH_SHORT)
                    .show();
        

        
        catch (JSONRPCException e)
        
          e.printStackTrace();
            Toast.makeText(getApplicationContext(),
                    "Error ON server connection", Toast.LENGTH_SHORT)
                    .show();
        

json 输出的数组

    [Logedin] => 1
    [drivers] => Array
        (

   
    [objects] => Array
        (

   

【问题讨论】：

感谢它在我将 放在 AndroidManifest.xml 上后工作，因为这个错误是由于套接字 permation 而发生的

【参考方案1】：

谢谢，我放了之后就可以了

<uses-permission android:name="android.permission.INTERNET" />

在AndroidManifest.xml 上，因为此错误是由于套接字权限而发生的。
