Android Studio中的AppEngine端点不包括建设者 [英] Android Studio appengine endpoint does not include builder
问题描述
在我AndroidStudio项目我有两个模块：应用程序，这是Android组件和API是应用程序引擎模块。通过在AndroidStudio创建一个端点应用程序引擎模块生成的应用程序引擎模块API。
In my AndroidStudio project I have two modules: app, which is the android module and api which is the app-engine module. The App-Engine module api was generated by creating an Endpoints App Engine Module in AndroidStudio.
我有一个从客观化注解的类名为评论生成的端点类。
I have an Endpoint class generated from an objectify annotated class called Comment.
package com.example.pontuse.api;
import com.googlecode.objectify.annotation.Entity;
import com.googlecode.objectify.annotation.Id;
/**
* Created by pontuse on 2014-09-08.
*/
@Entity
public class Comment {
@Id
Long id;
String who;
String txt;
public Comment() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getWho() {
return who;
}
public void setWho(String who) {
this.who = who;
}
public String getTxt() {
return txt;
}
public void setTxt(String txt) {
this.txt = txt;
}
}
后来我产生一个端点从类调用CommentEndpoint通过点击工具>谷歌云工具>生成端点
Later on I generated an Endpoint called CommentEndpoint from the class by hitting Tools > Google Cloud Tools > Generate Endpoint
package com.example.pontuse.api;
import com.google.api.server.spi.config.Api;
import com.google.api.server.spi.config.ApiMethod;

import java.util.ArrayList;
import java.util.List;
import java.util.logging.Logger;
import javax.inject.Named;
import javax.xml.ws.Endpoint;
/** An endpoint class we are exposing */
@Api(name = "commentEndpoint", version = "v1", namespace = @ApiNamespace(ownerDomain = "api.pontuse.example.com", ownerName = "api.pontuse.example.com", packagePath=""))
public class CommentEndpoint{
// Make sure to add this endpoint to your web.xml file if this is a web application.
private static final Logger LOG = Logger.getLogger(CommentEndpoint.class.getName());
public CommentEndpoint(){
}
@ApiMethod(name = "listComment")
public CollectionResponse<Comment> listComment(@Nullable @Named("cursor") String cursorString,
@Nullable @Named("count") Integer count) {
Query<Comment> query = ofy().load().type(Comment.class);
if (count != null) query.limit(count);
if (cursorString != null && cursorString != "") {
query = query.startAt(Cursor.fromWebSafeString(cursorString));
}
LOG.info("Calling listComment method");
List<Comment> records = new ArrayList<Comment>();
QueryResultIterator<Comment> iterator = query.iterator();
int num = 0;
while (iterator.hasNext()) {
records.add(iterator.next());
if (count != null) {
num++;
if (num == count) break;
}
}
if (cursorString != null && cursorString != "") {
Cursor cursor = iterator.getCursor();
if (cursor != null) {
cursorString = cursor.toWebSafeString();
}
}
return CollectionResponse.<Comment>builder().setItems(records).setNextPageToken(cursorString).build();
}
/**
* This inserts a new <code>Comment</code> object.
* @param comment The object to be added.
* @return The object to be added.
*/
@ApiMethod(name = "insertComment")
public Comment insertComment(Comment comment) throws ConflictException{
if(comment.getId() != null)
if(findRecord(comment.getId()) != null) throw new ConflictException("Object already exists");
LOG.info("Calling insertComment method");
ofy().save().entity(comment).now();
return comment;
}
@ApiMethod (name = "updateComment")
public Comment updateComment(Comment comment) throws NotFoundException{
if(findRecord(comment.getId()) == null) throw new NotFoundException("Object does not exist");
ofy().save().entity(comment).now();
return comment;
}
@ApiMethod (name = "removeComment")
public void removeComment(@Named ("id") Long id) throws NotFoundException{
Comment record = findRecord(id);
if(record == null) throw new NotFoundException("Comment record does not exist!");
LOG.info("Calling removeComment method");
ofy().delete().entity(record).now();
}
private Comment findRecord(Long id){
return ofy().load().type(Comment.class).id(id).now();
}
}
当我尝试在我的应用程序模块创建的AsyncTask做到这一点的Android应用程序可以使用App-Engine后端工作，我所需要的端点成员类生成器应该被实例化这样
When I try to create an AsyncTask in my app module do that the Android Application can work with the App-Engine Backend I need the Endpoints member class Builder which should be instantiated like this
CommentEndpoint.Builder builder = new CommentEndpoint.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null)
但IDE告诉我，有作为CommentEndpoint.Builder没有这样的事情。我用Google搜索<一个href=\"http://stackoverflow.com/questions/16726745/endpoint-builder-missing-for-generated-cloud-endpoint\">this问题但无济于事，由于Android工作室的作品与现在，而不是在应用程序引擎和Android应用两个独立的项目在同一项目中两个模块。
我错过了什么？
But the IDE tells me there is no such thing as CommentEndpoint.Builder. I googled this question but to no avail, since Android Studio works with two modules in the same project now and not in two separate projects for the app-engine and android application. Have I missed something?
推荐答案
我刚刚安装为0.8.9，并开始对涉及GAE的一个项目工作。
我有同样的问题，建设者没有确定。
I just recently installed AS 0.8.9 and began to work on a project involving GAE. I had this same problem with 'builder not identified'.
什么固定它，我被删除你的情况：
What fixed it for me was deleting the "in your case":
import com.example.pontuse.api.CommentEndpoint;
和重新导入它，它更改为
and re importing it which changed it to
import com.example.pontuse.api.commentEndpoint.CommentEndpoint;
添加依赖时，这一定是一个错误。
希望这有助于。
this must be a bug when adding the dependency. Hope this helps.
