i Already use this it uses a lot of memory tho! Thanks anyway

Out of intrest , have you.used gikdbg? Its a edited olly dbg for android good for finding stuff like oauth keys if they are buried in source.

Sounds very interested I'll defiantly take alook at this (if you really interested to grab the OAuth Token you could just use Fiddler as MITM I think This will gonna help You Extracting Instagram's Signature Key WITH GIKDBG)
