I am working on a project based on google mobile backend starter. This is set up to authenticate users using their google account - https://cloud.google.com/developers/articles/mobile-backend-starter-api-reference/#secmod
I now want to get a users name and profile image as defaults for their profile. I have implemented the google plus APIs which gives me the information that I want - https://developers.google.com/+/mobile/android/people
Unfortunately at the moment I am asking the user to log in to the application with their google account and then asking them to log in again to get their google plus information. So my question is this: is there a way to modify the google plus login such that it takes the authentication from mobile backend starter rather than requiring a separate login?
This is a similar question Can I use Google Plus sign in to authenticate my OAuth methods in app engine? but I specifically want my standard sign in to authenticate the google plus (rather than the other way around) as very few people have an android phone without a google account but a larger percentage dont have a google plus account
If in your application you provide a "Sign-in with Google" functionality then you can upgrade that functionality with "Google SignIn Plus". Please refer to the document [1].Also go through the document[2], it gives you an idea how to use the Google+Sign In with your android application.

I am doing an android app which uses only my Google account. I want to integrate my Gmail Account in my Android app. So each user who uses my app can use my Google account only . I want to set my Google account in static without using AccountManager Obj to display all email in their Mobiles.
Please Help me.
You can't do this. Gmail account cannot be bind to multiple device (there is a limit ... i don't know exactly but i know it)
Google keep rights to disable those account, check in google account android policy.
You got to let people use their own google play account.
In android I need to create an app where user can login through google account and can access its basic profile information and its inbox mails also. How do I integrate google plus API and gmail API together.
Also please let me know how to integrate gmail API to access mails.
Google+ sign-in lets users sign in to your Android app with their existing Google account and get their profile information like name, email, profile pic and other details. By integrating google plus login in your apps, you can get all the user details in one shot. Not only login, you can do other things like posting to their g+ account, getting list of circles, friends list and lot more. The major advantage of integrating G+ login is, you can drive more users to your app by providing quicker & easiest way of registration process.

I want to know if it is possible to sign in to my app using Google Plus without making app on Google Console?
You can't do it without creating app in console, since your app would need access tokens in order to login Google Plus. While creating an app on console, Signing Certificate FingerPrint (SHA1) is required to authorize your app plus explicitly enabling of this feature for your app.
So in short, you won't be able to login Google Plus, unless you authorize your app in Google Console.
Specify basic developer profile information about yourself or your company on the accounts detail page.This identifies you to Google Play and your customers. You can go back at any time to edit the information and change your settings.
Google uses the Google Developers Console to configure access for apps to communicate with the Google APIs.
Your web app must use the Google Sign-In button to prompt your web site users to download your app the first time that they sign in. This feature is enabled by adding the apppackagename parameter to your sign-in button.

Hence,it is not possible to sign in to your app using Google Plus
without making app on Google Console.

It is no way to sign in to your app without using Google Console.
If you just don't like the console, you can try this:

Is it possible to integrate both facebook and google in one app so as to in allow user to sign in for both ... i.e use google game services for Real time multiplayer and then at the end, post the result on facebook .. so in a manner where my app would hold both sessions fb as well as google ?? is thing this possible ???
yes of course , you can use the google+ API and the facebook sdk in your API.
you begin by Login your users by googles+.
in the end, if the user wants to share anything in facebook you authenticate him with facebook sdk, then ask for permissions then publish what you want.
you can find many tutorials and samples about the authentication in google+ and facebook.
I don't want to give advertisements about libraries (and I didn't even test anyone of them...) , I hear about GigyaSDK. they have a good documentation of integration.
I'm creating an app that will need users to create an account. (Like Facebook or Twitter would require you to.)
BUT, since it's an Android app, should/can I let them sign in with their Google Account using AccountManager or some other service? It'd be very helpful if they could just sign in to their Google account and their settings and other options would be saved to that account.
Main questions summed up:
Is it possible to let a user just use their Google account in my app?
If so, do I use AccountManager to have them sign in and save account information/settings?
What are other options?
Yes, you can get users to log into their Google Services using their Google credentials, for example, I have an app on Google Tasks and I use the Android AccountManager to let users authenticate themselves using their Google account on the android device (No need for users to enter their password!)
There are some really good examples to get you started:
This is an in-depth look into how you can authenticate based on the users Android credentials, has an example of how things work and how the UI should be: http://www.finalconcept.com.au/article/view/android-account-manager-step-by-step-2
This is an example of getting AccountManager to work with a Google service like Google Tasks: https://developers.google.com/google-apps/tasks/oauth-and-tasks-on-android
The last example is using the same concept for accessing the Google Picasa service: http://code.google.com/p/google-api-java-client/wiki/AndroidAccountManager
The other options you have is to have users manually enter their username/password. For that you have to use a third party authentication API (like signpost for OAuth) for them to log in.
In my tasks/todo application I provide users both options to sign in, using their android credentials or using third party authentication for users that want to log in using some other account (an account which is not enabled on that device)
Let me know if you have more questions
Although it is a new development, Google Plus Sign-in introduced as part of Google Play Services can also be used. More info can be found at Android developers blog. See example implementation from Banjo app
There seems to be a big limitation - The user need to have Google+ app installed on the device to use this.
Also this is a pretty good blog if someone is interested in implementing the solution.
#Soham gave you some very useful links but he didn't correct one major error: AccountManager is the entity that manages the accounts on your Android device - it has nothing to do with your google account! you can use google account and create a NEW account on your device using the AccountManager.
The rest you can learn from the links Soham gave you.
