I want to create an app for an android tablet. It is basically just 6 to 12 simple games I need to create.. The pad doesn't have to do anything else. People will play these games, be scored by time and achievement, and it needs to record these scores per user. It's a dexterity test basically.. Should I buy a basic cheap tablet? How do I design the games? Sorry to bother anyone, just need advice. Thanks!!
