I want to implement single User OAuth in android side or in other words need some API for it.
Have a look at signpost, it's a Java library for OAuth (1.0a, 2.0 is not yet supported).

I have been using the Eddystone platform for a few months now, and things are working well. However, when registering new beacons, I am finding myself needing to open Google's OAuth 2.0 Playground and all the steps associated with it in order to send a PUT request that contains my new base64-encoded Eddystone-UID.
Is there any way to register beacons with Eddystone without having to use the OAuth 2.0 Playground? I would like to build a standalone desktop Java application that automates this process, so any Java tips would be much appreciated.
Thanks!
Yes, you can use Google's APIs to do an OAuth 2.0 sign in and then make the web service calls to the Proximity Beacon API. The key part is setting up OAuth 2.0 on your Java client. These two documents might help:
Using OAuth 2.0 to Access Google APIs
API Client Library for Java
Once you have an OAuth token, you can call the APIs as described below. You may have already done this if you are using the playground.

I am developing an IOS app. I need to get Evernote note books using rest api. I don't want to use Evernote SDK. Is there any rest api available?
I succeeded to get oAuth Access token without using SDK.
Evernote does not have a publicly available REST API. Evernote's iOS SDK has been rewritten recently, is very easy to use and is available here: https://github.com/evernote/evernote-sdk-ios
Evernote uses a binary protocol based on Apache Thrift to communicate with its clients including 3rd party clients such as your application, not HTTP. OAuth is a HTTP based protocol and is independent from Evernote's client-server binary protocol communication.
I have created a Web application in Google App Engine java. Now I want to provide the authentication functionality. User can use his twitter(in future I will provide other OAuth Service provider too) account for login. I have found couple of libraries for twitter authentication like twitter4j. I don't want to use any such kind of library that specifically work for single social site like Twitter, facebook etc. I thought to do oauth implementation by my self. I have pretty good knowledge about oauth mechanism and found google oauth java client library. This library provide the functionality of oauth and is not dependent to any kind of social site(to my knowledge). Unfortunately I didn't find good examples on this library. Can any one help me about the examples, tutorials or any other library that is not dependent to any particular social site.

There are lots of resources describing OAuth usage in terms of clients, Facebook/LinkedIn/Twitter API usages. This is ok. But I am interested in OAuth server implementation. The aim is to have the web application which also can be accessible by the mobile devices (native applications), so I need to setup OAuth on my back-end Java server. So I would like to know how LinkedIn/Facebook/Twitter implemented OAuth on their server side, and distinguish users between auth_token-s and grant the corresponding access (some kind database mapping - auth_token = user identity?).
Or maybe there is the better way to authenticate mobile user (I'm going to use REST style services for back-end)?
Facebook, LinkedIn and Twitter have implemented OAuth following the specifications for OAuth 1 (Twitter LinkedIn) and the draft for OAuth 2 (Facebook, LinkedIn).
I would suggest going for OAuth 1, or OAuth 2 User Agent Flow. If your mind is set on OAuth that is. You could always go for simple basic authentication to begin with and focus on the really hard parts, namely the design of your API itself.
If your mind is set on OAuth, check out this list of code libraries: http://oauth.net/code/. And also read up on the specifications, if you want to implement an OAuth provider, you have to know and understand the specs. Otherwise you are in for a world of pain looking for out-of-the-box libraries that will solve everything "OAuthy" for you.
I need to use oAuth in order to login to my website (with a Twitter account). The backend of the website will be created using Java and the front end will be created using JSP/JSF. Is there any Java based stable API that i could use to connect to Twitter using oAuth ?
Note :
I am aware that there is OAuth and xAuth, i think xAuth uses a pin verification method. What i want to have in my site is a OAuth verification that doesn't use a pin based verification method.
twitter4j - stable and active.
I'm a big fan of Scribe
I created an simple JSP/Spring/twitter4j example.. Twitter OAuth
if you are using Spring you can use Spring Social which can do this for you.
