I would like to thank Packt Publishing for offering me the opportunity to write this book. I would particularly like to thank Parita Khedekar, Rebecca Youé, and Amey Sawant for their valuable help.

I would also like to thank Antonio, the co-author of this book, for making everything so easy; my new friends of adventure, especially Paloma, Camilla, and Adrián, for these last months; my friends from way back for visiting me; and finally, my family for supporting me.

Antonio Hernández Ni?irola has an engineering degree in Computer Science and is a mobile application developer. He was born and raised in Murcia in the southeast region of Spain and is currently living in Rabat, Morocco. He has developed several websites and mobile applications.
