Почему я получаю ошибку в Android при вставке данных с использованием конечных точек Google App Engile?
Я получаю доступ к конечным точкам из проекта Android. Проект App Engine успешно развернут.
Вот мой код Android:
Usermasterendpoint.Builder endpointBuilder = new
Usermasterendpoint.Builder(AndroidHttp.newCompatibleTransport(),
new JacksonFactory(),
new HttpRequestInitializer() {
public void initialize(HttpRequest httpRequest) { }
});
Usermasterendpoint endpoint = CloudEndpointUtils.updateBuilder(
endpointBuilder).build();
System.out.println("End of Asynk Task is...................///////////");
try {
UserMaster userManager = new UserMaster();//.setDescription("Note Description");
String userID = new Date().toString();
userManager.setUserID(userID);
userManager.setEmail(Email);
userManager.setUsername(username);
userManager.setPassword(password);
UserMaster UsermanagerResult = endpoint.insertUserMaster(userManager).execute();
Вот мой класс сущностей UserMaster. Который я пытаюсь использовать сверху код Android.
