Yes, "how you doin' " here is the same thing as "how are you doing", it is just shortened for convenience. In spoken English, the contracted forms of phrases are commonly said more often than the full forms. So "how are you doing" in spoken English is normally said as "how're you doing", or if you are speaking more informally, it may be "how're you doin' " or "how you doin' ".
