Android Application with REST query

Our company need to create an android application with the standard Android layout. The purpose of the app will be to give to the user some features to do before to go in an hotel (we have 400 hotels in our database) The first screen of the app will ask to the user to insert the code of the hotel that they have or if they don't have just to write the name of the hotel... the app will search through an JSON API that we provide and will set this hotel. When the hotel is set, user will have a side menu where it will be possible to select : 1.

When he click on submit the app will send an e-mail to the hotel (the e-mail address is given by the API on the first selection) 2. Check-in It is a simple form where the user can upload a 2 photos (his ID card) and some fields like, name, surname, birth date. When press submit, the app should send an e-mail to the hotel with attached the id card loaded by the user. 3.
