Hey there,
First of all i would like you to know that though I'm new to freelancer but that doesn't mean i'm new to android app development. I have vast experience developing android and windows phone apps as i was working in a Mobile app development company.
I can do almost anything related to Android(I'm expert in implementing networking technology in android i.e API's). I have Implemented almost everything available in market during my work in our company, so basically i can develop or fix almost anything related to android. you can completely trust me on this. I have worked with API's of NBA, Steam, and many google API's though i have never worked with Expedia API, but the underlying concept is same in almost all API's, therefore i am confident that i can work with this also.
NOTE: Since I'm new to freelancer its obvious that you would have problem trusting me, so considering that I'm ready to do your work for very less amount while also maintaining high quality of work that is delivered on time(I have to start somewhere so I'm offering my professional services for very less amount)
I can definitely help you out while also being easy on your wallet so..
CONTACT ME IF YOU HAVE ANY DOUBT OR HAVE FURTHER QUERIES, I'm ALWAYS AVAILABLE!
