Login on facebook from an android app

Question

In my app I have a 2 edittext (for email and password) and a simple button "Facebook connect" and when I choose this button I want to go to sign in page of facebook. Is it possible what I am trying to do or I must login on facebook from facebook login page? If it's possible,how should I do this?

Answer 1

you have to download api from this link https://github.com/facebook/facebook-android-sdk/

and after that take code for facebook api of java from this link

http://developers.facebook.com/docs/guides/mobile/

Answer 2

try this:

public void onClick(View v) {

        Intent i = getOpenFacebookIntent(this);
        startActivity(i);

    }


public static Intent getOpenFacebookIntent(Context context) {

    try {
        context.getPackageManager().getPackageInfo(
                "com.facebook.facebook", 0);
        return new Intent(Intent.ACTION_VIEW,
                Uri.parse("fb://profile/20531316728"));
    } catch (Exception e) {
        return new Intent(Intent.ACTION_VIEW,
                Uri.parse("https://www.facebook.com/facebook"));
    }
}

when you click on your button (or for example a facebook icon as an image button)

Your android browser will pops up and then you can login to facebook.

In the code above I use the page facebook.com/facebook to be browsed but you can use any other page you like but first you need to exctract the page's id from here:

graph.facebook.com/yourpage

(for example in code above the id is 20531316728 where you can find it in: graph.facebook.com/facebook)

Answer 3

did you have a look at the official Facebook Android SDK? android-sdk

Answer 4

You have to follow https://github.com/facebook/facebook-android-sdk/

Here the idea is avoid login in your app if you have already logged into official facebook app. Otherwise it will pop up an custom dialog.
