Facebook Like Button In WebView With SDK

I'm trying to implement Facebook Like button which is not part of Android Facebook SDK using WebView. The idea is very simple. I use SDK to log into user account using SSO so user

Solution 1:

I'm not quite sure about FB app access token being valid for using the web api, but let's try something.

First, make sure you're actually using cookies for your WebView instance:

CookieManager.getInstance().setAcceptCookies(true);

I'm not sure whether the facebook redirect page will try to set cookies, so try this and see if it does the trick:

webview.setWebViewClient(new WebViewClient() {  
  @Override  
  public boolean shouldOverrideUrlLoading(WebView view, String url)  
  {  
    view.loadUrl(url);  
    return true;
  }  
});

This will force your WebView to open links within itself, so cookies - if any - won't be lost in case the like page issues a redirect.

If problem still persists you can also try setting cookies manually by executing this before you load the url in your WebView:

// This just initializes the sync manager, do it once
CookieSyncManager.createInstance(this);

CookieManager.getInstance().setCookie("facebook.com", "token="
        + mFacebook.getAccessToken() + "; domain=facebook.com");
CookieSyncManager.getInstance().sync();

Solution 2:

I think this is what you are looking for: https://developers.facebook.com/docs/authentication/server-side/

If I'm reading this correctly, once you implement OAuth, you can use the Graph API to implement the "Like" button you are looking for because you can authenticate the device - not just the user.
