Different Mobile Phone Platforms
©Avinash Kumar Shudhanshu
• Tools are free and run on all devices• Market registration is the cheapest at 25$ onetime fee.• OS is free : Advantage better understanding• More Free Apps : Better for the user , moreuser = larger market

Why Android
Cost:
• Was designed to run on multiple devices.• Configuration qualifiers for resources• UI Design based on rules rather than absolutepositions.
Multiple device support
©Avinash Kumar Shudhanshu
• Allows an app to pass messages acrosscomponents and between apps.
• Allows other apps to fulfill requests withoutknow about the app. Eg : Share Intent.
• you can take action and respond without opening whatever app first (for example, I could email Cody without first separately opening the mail app).

Customization
• If you want to customize your smartphone, the sky's the limit with Android. Alter whatever you want. You can even download an iOS or win 8 theme, if that's what you're into.
• You can replace Android's default keyboard with any third-party alternative (like the easy-to-use and fairly self-explanatory Swipe).
• you can set multiple users accounts on one device, limiting the information that each user can see. Can't do that on the iPad.
