If you are a mobile games developer, one platform that would be a no-brainer to enter these days would be Android. Just this week, mobile analytics firm Flurry announced in a report that combined iOS and Android new app downloads from December 25-31 topped 1.2 billion. This holiday season number is crazy and yup, if you are not developing for Android, you are just shooting yourself in the foot.

One developer that has reaped the rewards for going Android is Disney Mobile and they’ve been nice to share some figures from the same holiday season period which they have experienced some significant growth. Disney Mobile’s Holiday iOS installs increased 40% this holiday season, compared to the same period last year.

This was the first holiday season for Android as a viable mobile gaming platform, for the first time making up a significant portion of Disney Mobile’s overall downloads. Swampy (Disney Mobile’s original character for Where’s My Water) continued his hit streak on both iOS and Android, illustrating how great character, story and gameplay is the winning combination for consumers.  For the week of December 25-31, the app was downloaded more than 6 million times across both iOS and Android.
