Styling FacebookActivity to avoid terrible progress bar

I just implemented logging in through Facebook using their SDK in conjunction with ParseFacebookUtilsV4.

In my manifest I had to declare a FacebookActivity that gets launched when I try to sign in, and that works great.

<activity android:name="com.facebook.FacebookActivity"
android:label="@string/app_name" />

This snippet comes from official docs so I didn’t choose anything. What I found really weird is its styling. On my emulator (API 22) it has a ProgressBar that seems to be coming from the ’90s! Is there a way to style it? I have tried changing the android:theme attribute, but with no success.

I thought of extending com.facebook.FacebookActivity, but after digging through source code I found out it inflates a com.facebook.LoginFragment, which is then responsible of the progress bar actually. Any ideas?
