我需要帮助，这似乎是一个简单的问题，但我坚持了好几天。我正在尝试使用 Azure 移动服务来保存我的 Android 应用程序中的数据。我现在遇到的问题是我有一个数据传输对象，其中有几个字段对应于 Azure 数据库表中的列。这是一个简单的表，遵循所有步骤......我做错了什么？

    package com.bn7.rotabn7;
    import java.net.MalformedURLException;
    import com.microsoft.windowsazure.mobileservices.*;
    import android.os.Bundle;
    import android.app.Activity;
    import android.util.Log;
    import android.view.Menu;

    public class MainActivity extends Activity {
        private MobileServiceClient mClient;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            try {
                 mClient = new MobileServiceClient( 
                        "https://ocamorana.azure-mobile.net/", 
                        "hCzcrsFYhkGmxPvQDNxyqBXjZwjXlK99", 
                        this 
                        );
                Item item = new Item(); 
                item.IdPhone = "Awesome item"; 
                item.DateTimePhone = "Awesome item"; 
                item.LatitudePhone = -43; 
                item.LongetudePhone = -23; 
                item.ActivePhone = false; 
                mClient.getTable(Item.class).insert(item, new TableOperationCallback<Item>() {
                     public void onCompleted(Item entity, Exception exception, ServiceFilterResponse response) { 
                        if (exception == null) { 
                             // Insert succeeded 
                                                } else { 
                             // Insert failed
                            Log.d("Insert failed", "*---------------------------------------------------------------*");
                            Log.d("Insert failed", "Error in activity", exception);  // log the error
                            Log.d("Insert failed", "*---------------------------------------------------------------*");
                        } 
                     } 
                });
            } catch (MalformedURLException e) {
                Log.d("MalformedURLException", e.toString());
            }
    }


        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.activity_main, menu);
            return true;
        }

    }

    package com.bn7.rotabn7;

    public class Item { 
        public int Id; 
        public String IdPhone;
        public String DateTimePhone;
        public double LatitudePhone;
        public double LongetudePhone;
        public boolean ActivePhone;
        }

我的第一个猜测是您缺少清单中的 Internet 权限（因为它抱怨 UnknownHost 这通常表明应用程序无法连接到 Internet）。确保这是在您的清单中：

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