Comments for Brad Abrams

Make a copy of folder lib in same -Android/ and rename to libs. It will work. I also spend 1 week to resolve this.

Hi,

Since Eclipse 4.2 (and I guess since C2DM has been deprecated in favor of GCM https://developers.google.com/android/c2dm/) there is no “App Engine connected Android project” available, is there any equivalent? I’m mostly interrested in the android to App Engine part :-) .

Still alive?

Only one year and it is deprecated. And there is no documentation about whats going on. Can you at least provide a simple application that works without C2DM. Just authentication, storing and retrieving data.

thanks i will use it for my android app at http://droidsoft.fr

Brad, thank you for putting up these server configuration details. This was exactly what I needed to get up and running with GCM.

Is there any other documentation for the mobile backend project? Every time I try to run the app I get errors saying files are missing. Any help would be great.

This looks great – many thanks.

I’m having some trouble adding authentication to the android client – when I try to create register the new application for the API, it reports:

Error (projectId=YYYYYYY)

OAUTH_CLIENT_KEY_ALREADY_EXISTS: OAuthClient key exists

(I have replaced the project ID with YYYYYYY)

I’m not sure if this is a config issue internal to my app, or if it’s a consequence of using the android debug keys.

I’m going to dig around for a good primer on app engine client authentication…

Probem solved by (I think) deleting the same creds on another test app – that was deleted.

(had to undelete the project via the old console https://code.google.com/apis/console , then delete the creds within it, then delete the project again.)

I think possibly creds are valid globally even after an app has been deleted – presumably until the app has been fully deleted (ie undelete is no longer available.)

I’m not 100% sure, but posted this in case anyone has the same issue.

java: package com.google.api.client.googleapis.services.json does not exist

java: cannot find symbol

symbol: variable super

location: class com.google.cloud.backend.android.mobilebackend.MobilebackendRequestInitializer

etc :S
(Android Studio)

Are the results the mobile client gets from querying the backend also stored locally in the mobile device ( something like a sqlite db), so that everytime the user starts the app it would not retreive all the records.

I am a newbie to cloud storage, please dont shout at me if my question seems stupid.

I wander if you can hel me. I’m habing a really weird behabiour.

I used the basic backend starter client code and tweaked it just to insert cusmtom data (didn’t actived authentication yet).

The weird thing is that the insertions works fine for some time, but if some ours after I try (without change in the code) do more insertions I get the :

com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found

and keep failing till I redeploy the mobile backend and let pass some minutes.

I’m just perplex an furstrated. Can you give me any idea why is that happening?

Anyway thanks for the post and the IO video.

Try exporting the project from Eclipse (you might need to add a local.properties file as well) before importing to Android Studio, it’s working on Android studio for me after doing this.

I too was getting 404 responses in the Android client. When I looked at the App Engine side it was reporting configuration errors. I found that I could get rid of the errors by setting the values for Audience and Client Ids in the Mobile Backend Settings.
