有关Android中内存问题的问题

Question

如果我们在Android中使用大量逐帧动画，会不会出现内存问题

Answer 1

That depends entirely upon how you implement it, and details such as how large your frames are and what kind of color-depth you choose to use. In general, however, you should be able to come up with a rendering algorithm that doesn't hold references to more than a handful of frames at any one point in time.

Ideally you should only need a reference to the previous frame and your working buffer for the current frame. Assuming that's the case, and assuming that you're using 8-bit RGBA pixel encoding, then you can easily work out how approximately much memory your animation will consume when running. It's:

frame.width * frame.height * 4 * 2 bytes

And then from that you can make a reasonable estimate of whether or not your device can meet your memory requirements. As a general rule, as long as your frames are not larger than your device resolution you should be okay.
