我需要帮助,似乎是一个简单的问题,但我坚持了几天。我正在尝试使用Azure Mobile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,按照所有步骤......我做错了什么?

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>() {

}
}
});
} catch (MalformedURLException e) {
Log.d("MalformedURLException", e.toString());
}
}
@Override

我的第一个猜测是你错过了你的清单上的互联网许可(因为它抱怨UnknownHost,这通常表明应用程序无法连接到互联网)。确保它在您的清单中:
<uses-permission android:name="android.permission.INTERNET" />
