我按照下面的教程进行操作。
https://developers.google.com/eclipse/docs/running_and_debugging_2_0
这基本上为我现有的应用程序添加了一个 GAE 后端。然后我尝试下面的示例,在本地开发服务器上运行它,我得到下面发生的异常
Note result = endpoint.insertNote(note).execute();
叫做。
com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found
我的代码如下。
package com.cloudnotes;

import android.view.Menu;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new EndpointsTask().execute(getApplicationContext());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public class EndpointsTask extends AsyncTask<Context, Integer, Long> {
protected Long doInBackground(Context... contexts) {
Noteendpoint.Builder endpointBuilder = new Noteendpoint.Builder(
AndroidHttp.newCompatibleTransport(),
new JacksonFactory(),
new HttpRequestInitializer() {
public void initialize(HttpRequest httpRequest) { }
});
Noteendpoint endpoint = CloudEndpointUtils.updateBuilder(
endpointBuilder).build();
try {
Note note = new Note().setDescription("Note Description");
String noteID = new Date().toString();
note.setId(noteID);
note.setEmailAddress("E-Mail Address");
Note result = endpoint.insertNote(note).execute();
} catch (IOException e) {
e.printStackTrace();
}
return (long) 0;
}
}
}
