Android Facebook SDK 4.0 Login without Facebook App

Question

I\'m having issues with the webview login for Facebook on Android.

I\'ve followed the tutorials and login works perfectly when the user has the Facebook app install

Answer 1

I think you forgot to use callbackManager for proper workflow. Used CallbackManager for registration callback must be called in onActivityResult of host activity. Activity should not be in singleInstance launchMode because it will not be able to launch startActivityForResult(facebook internally launches FacebookActivity using this method). So add to your activity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
}
