Link to login to social Media from app

Question

In my app I want to have a link or button that can use stored credentials to login to social media sites - say facebook. But, since I plan on having a multiple links/buttons to different sites that may use different login info, I cannot force users to login to my app using any of the social media credentials.

Please forget the storing of credentials for now - that is a different issue altogether.

My question is Can I send the user's info to Facebook to allow them to login without having to take them to the login screen? If so, where to best find the information to do that?

Sorry if this is a noob question, but I am a noob to app dev and still trying to get my direction. Any sites or links with information would be appreciated.

Answer 1

sorry for the answer but from my experience you need to go through Facebook API to log in an android application using facebook,same for other social network. No clue what you wanted to do use a HTTP POST with the credential ?

There is a serious security issue with what you're trying to do, because it's you're application that handles the social network credential and so you would need to encrypt them store them and so on...

So if you want to give a try to Facebook Android API it's here : https://developers.facebook.com/docs/android/getting-started/

Dealing with the Facebook API is too much easy. You will follow some steps to import it into your project. Register your App on facebook developer site. Put the facebook button into your layout .

When the user clicks on the button the API will handle all the subsequent steps starting from taking the user username and password and will reply to you with a temporary accessToken that will be valid for two months. This is the only communication way with Facebook API , if you want to give the Facebook API any info with any other way. I am sorry to tell you you will not be able to do that.
