无法将App Engine端点导入Android Studio中的EndpointsAsyncClass

我尝试在Github上构建自己的EndpointsAsyncClass版本。这是我的实现：

package com.example.pontuse.helloendpointsproject;

import android.content.Context;
import android.os.AsyncTask;
import android.util.Pair;
import android.widget.Toast;

import com.google.api.client.extensions.android.http.AndroidHttp;
import com.google.api.client.extensions.android.json.AndroidJsonFactory;
import com.google.api.client.googleapis.services.AbstractGoogleClientRequest;
import com.google.api.client.googleapis.services.GoogleClientRequestInitializer;
import com.google.devrel.samples.mymodule.api.commentEndpoint.CommentEndpoint;

import java.io.IOException;

/**

 */
public class EndpointsAsyncTask extends AsyncTask<Pair<Context, String>, Void, String> {
private static CommentEndpoint myApiService = null;
private Context context;

@Override
protected String doInBackground(Pair<Context, String>... params) {
    if(myApiService == null) {  // Only do this once
        MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),
                new AndroidJsonFactory(), null)
                // options for running against local devappserver
                // - 10.0.2.2 is localhost's IP address in Android emulator
                // - turn off compression when running against local devappserver
                .setRootUrl("http://10.0.2.2:8080/_ah/api/")
                .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                    @Override
                    public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {
                        abstractGoogleClientRequest.setDisableGZipContent(true);
                    }
                });
        // end options for devappserver

        myApiService = builder.build();
    }

    context = params[0].first;
    String name = params[0].second;

    try {
        return myApiService.sayHi(name).execute().getData();
    } catch (IOException e) {
        return e.getMessage();
    }
}

@Override
protected void onPostExecute(String result) {
    Toast.makeText(context, result, Toast.LENGTH_LONG).show();
}
}

但是，Android Studio不断告诉我，我必须将端点类移至我的应用程序模块。除了听起来令人难以置信的事实之外，我目前正在关注一个教程，并且没有提及任何内容。当我尝试通过技巧中提供的方法来执行此操作时，它声称该程序包甚至不存在。是的，它确实存在，并且导入上的名称确实是它的名称。我想念什么？
