OAuth.io + Fitbit authentication problem

[Argafarbrorn]

Hi

I was trying to authenticate my app with fitbit's api using a sample app provided by auth.io (https://github.com/oauth-io/oauth-android). I add an extra button to connect with the provider "fitbit":

fitbitButton.setOnClickListener(new View.OnClickListener() {
 @Override
   public void onClick(View v){
     o.popup("fitbit", MainActivity.this);
     }
});

 I've also added fitbit as a provider in my oauth.io-account.

So when I launch my app it first looks like this:

Then I try to connect with fitbit:

After signing in I get this message and I have to push "back" to return to my app.

But after that nothing happens. I don't think the "onFinished" method is ever called. Does anyone know what the problem is? I'm pasting the full code below...

package com.example.oauth_example;

        final OAuth o = new OAuth(this);

When you get the oauth_verifier you need to do one last step, request access_token.

see https://wiki.fitbit.com/display/API/OAuth+Authentication+in+the+Fitbit+API for more details section: POST /oauth/access_token.

Since you're using oauth.io library you may need to read oauth.io's documentation on how to properly request access_token or debug the code to understand how to do that.

It is not too clear from the code why the onFinished icon is not called. You probably need to debug the code to understand how the oauth.io works. 

Also beware the this is library is official one for oauth.io, and not for Fitbit. Althouth it may work it's not guaranteed it will work with Fitbit API.
