I'm trying to create my first Android game and I'm currently trying to figure out (with someone that will do the drawings and another programmer) what the best way to create animation is. (Animations such as a character moving, etc.)

At first, the designer said that she could draw objects/characters and animate them with flash so she didn't have to draw every single frame of an action. The other programmer and I don't know Flash too much so I suggested extracting all the images from the Flash animation and making them appear one after the other when the animation is to start.

He said that would end up taking too much resource on the CPU and I tend to agree, but I don't really see how we're supposed to make smooth animations without it being too hard on the hardware and, if possible, not have the designer draw every single frame on Adobe Illustrator.

Can an experienced Android game developper help me balance this out so we can move on to other parts of the game as I have no idea what the best way to create animations is.
