Cocos2d-Android run app on many devices

Question

I want to make cocos2d game for android that run on every device. I have idea to resize images when application is loaded for first time. I have some questions about that. Is this good idea? Can I save resized images on assets folder?

Answer 1

Generally speaking it would work technically but will lead to lower image quality due to upscaling or downscaling issues. You can hardly achieve the same image quality when scaling images on the device compared to doing that using an image program.

The preferable approach is to design images for all supported resolutions, and only if the device resolution is marginably different use the same assets but merely layout them slightly differently.
