Why Android

What should I develop

Where is my target customer

What my customer needs

Who will pay for my app

What else I should know Functionality is import but Usability is more important Is the application simple to use? How does your app integrate with device Location, movement, accelerometer, SIP, Near field communication, Camera Social connection how does the application allow the user to connect to other people in existing mobile communication paths such as SMS, IM, or voice? How is UI app UI design Does user has option switch skins How is App Integration with Home- Screen

Where can we start  Regional applications  Synchronization & sharing users data  Games & Productivity apps  Social Applications  Applications for large customer base  Schools or Universities, Health sector  Kids & Education sector  Optimization with Native porting
