I learned Google App Engine by creating some simple application using Java.
I came to know that Google App Engine use google account like gmail, to deploy those application. I had deployed those application with my account(a gmail account). In some place Google account are blocked in Colleges, Schools, Companies, but they will allow some other mailing website like Outlook. I am also having email account like Outlook, Is it possible to deploy application with other email id like Outlook account?, if yes, how to deploy it.
Thanks!
Yes it's mandatory to sign for Google cloud like you have to sign up on aws to deploy an app on aws
I'm not sure to fully understand your use case but note that you can add a new user to the project you want to deploy to by going to the IAM & Admin page in your Developer Console and add a new user with your Outlook email address and give him the owner role (or more fine-grained permissions if you prefer).
Then, to deploy your app, from your local machine for example, you can authenticate your gcloud (gcloud init or gcloud auth login) with this new account and run gcloud app deploy as usual.

Is there a way to authenticate a java desktop application with Slack using OAuth2? I am trying to follow Slack's guide.
I am getting stuck because it says you get the access token inside of the redirect uri of your application. But since the app I am making does not exist inside of the web browser, is there anyway I can do this?
Can my java application launch a localhost site that it can communicate with to use as the redirect uri? If so, how?
Desktop app as internal integration
Before we get into more details please note that there is an easy solution if you plan to use your desktop app for your own Slack workspace ONLY. In that case your app does not need to support the full Oauth work flow and you have two options:
Install your app as internal integration via the management page
of your Slack app and then copy & paste the token to your desktop app
Create a legacy token for your Slack workspace and then copy & paste to your desk (not recommended)
I also like to clarify upfront that your app only needs to run the Oauth process ONCE for installing it into a new Slack workspace. The resulting token has no expiration date and has not to be refrehed.
Desktop app for multiple Slack workspaces
If you plan to distribute your desktop app to multiple Slack workspaces you will need to support the full Oauth installation process.
Slack is using Oauth 2.0, so in principle all the standard answers from this older Oauth wiki article should work for Slack too.
However, since you can not assume that the local machines of your users are reachable from the Internet (e.g. redirecting back to a local web server will not work, since Slack will most likely not be able to reach it), you will need a web helper app that runs on a web server and is reachable from the Internet.
This web helper app is basically a small web site, which performs the complete Oauth dance for the installation process into a new Slack workspace. You app can open a browser window and redirect to the web helper app to start the login process. You then have two basic approaches how to handle the connect back to your desktop app:
Show the resulting token to the user and ask him to copy & paste it
to your desktop app (simple approach)
Store the resulting token in your web helper app and provide an API to your desktop app to fetch it automatically. (user-friendly approach)
If you are looking for a starting point for such a web helper app, take a look at this example PHP script for installing Slack apps.
Hi I have developed an web application using google app engine, for google shared domain contact, Its working fine when I am running it in the localhost but when I deploy that application into google app engine it showing warning screen before user conforming for consent(as shown in the image).
I am using 2 scope http://www.google.com/m8/feeds/contacts/ and https://www.googleapis.com/auth/userinfo.email. when I try to add a user information in the google shared contact I am getting a exception message as www.google.com. How can I resolve the problem? am i need to verify my application in the oauth_app_verification. Can any one solve this?
Thank you.,
You need to go through the verification process before you launch your app. This new process came recently to protect user's data. You can start the verification by submitting this form but before it is recommended to follow steps here
I have enabled Google Drive API on Google Developer Console and created a service account credential which is bundled with a service account ID and key ID. Despite that I have tried various ways to manage my own Google Drive account, I could not find a solution which fits for my aim. I need to upload, download and delete the files stored in my own Google Drive. The application that I am going to connect Google Drive is a console one which will be solely used for an academic research.
it's pretty simple. The steps to achieve this are at How do I authorise an app (web or installed) without user intervention? (canonical ?)
Be careful about how securely the refresh token is being stored and what scopes you grant to the app.
So I'll start from the beginning. I want to create an Android application and a server (written in java). The server will be written in Java. What I want to do is to be able to log in to my server from the Android application, using the Google account. After the device is logged in, there will be some information sharing with HTTP Requests. I want to use REST.
How should I proceed for achieving my goal? I guess I should use the Google API and Google App Engine. What should I do to implement the log in and the part in the server. It's first time for me writing a server and an application with log in, so any advises will be appreciated. The application is for educational purposes. Thanks in advance!
I would really suggest you give Google App Engine a try, specially combining it with Cloud endpoints which are designed to connect your server to clients like an Android App. Using endpoints you'll get cloud infrastructure + REST services + native libraries ( for Android, JS and iOS) and everything related to authentication is already sorted out (via OAuth).
App Engine can also be developed using Java and it's already integrated with popular IDEs like Eclipse (through the Google Plugin) and Android Studio (as backend modules) so you prbably have everything you need to star working on your App Engine server.
Use Google Play services (you don't need App Engine).
Here is the complete process with code samples: Authorizing with Google for REST APIs
Another option you can look at: Google+ Sign-in for Android
On the server side, once you have the auth token, you access the Google REST API with the username and token, and Google will tell you if the access is authorized.
I understand what you're trying to do. Your user already has a username and credentials on Google, why not just get the username and let Google do all the authentication?
However, you might want to re-think this approach.
The problem is that you will ask your user to sign in to Google and Google will ask the user (through logic in the Android API code) if your application can have access to their information in Google. Your users may balk at granting that kind of access to your application, and that will hamper your efforts to get people to use your app.
Now, if your app actually uses the Google REST APIs, then this would make more sense, because the auth token your app requests will provide access to a Google API.
But if all you're doing is authenticating, your users might be hesitant to authorize your app for some Google operation they don't think you need.
To get a feel for the OAuth 2.0 message flow, you can use this: OAuth 2.0 Playground
I want to send emails from my app engine application using one of my Google Apps accounts. According to the GAE python docs:
The From: address can be the email address of a registered administrator (developer) of the application, the current user if signed in with Google Accounts, or any valid email receiving address for the app (that is, an address of the form string#appid.appspotmail.com).
So I created a user account on my Google Apps domain, no-reply#mydomain.com, to use for outbound email notifications. However, when I try to add the user as an administrator of the app, it fails with this error:
Unauthorized
You are not authorized to access this application
Is it possible to configure app engine to send emails using a Google Accounts email address?
You must restrict your App Engine app to a Google Apps domain upon initial registration of your App Engine application ID. Unfortunately, this setting can only be set during the initial registration of your app ID.
What you'll need to do is register another application ID, set your authentication option for Google Apps domain, and upload your existing app to the newly registered ID.
Simply going through the "Domain Setup" process in your Dashboard is not enough; you'll only be able to add the app as a service and "host" it using your domain name. To restrict the authorization to your domain only, you'll need to do the first step in the initial registration.
I had also problems adding administrators. In the end, I used a regular gmail account as the sender. Which only works if sending as *#googlemail.com. *.gmail.com fails.
