Image Resolution and file size

aditya

The way I see it, we have two options:
1) Adding a base image and other images for different resolutions and defining them like so @2x
2) Putting in images of the highest resolution and scaling them down to fit the screen.

Wouldn't the first method increase the file size by quite a bit? Is there a reason why we don't use the second method?

I prefer first option yes it will increase the final binary size but that is ok most of people really dont care about this however file size > 50 mb is little bit problem.

the reason for not using bigger resolution image is it will take much texture memory even when using in small resolution device and quality will not look good when we downscale them at considerable size try below image in smaller resolution device and see the diff

Good point on the texture memory, didn't think of that.

A single background image for the highest resolution has a size of 1.5 mb. If we add up the size of a single image in 3 resolutions, it goes upto 2 mb.

In my opinion, any game of more than 30 mb would have a hard time being downloaded on impulse unless it's a big publisher, so there's that concern.

At the risk of sounding naive, why not publish multiple apks by changing the art required according to different screen resolutions and "supports-screens" instead of a single, large file with the art being picked up as @2x etc?

For androids, that might not be such an issue, for apple, they might reject your app.

Plus from a users point of view, would I want appHD, appSD, appMD and appXD instead of just app. That is the reason why there is one API than multiple, plus I might have an sd phone and I might have purchased the app, now when I have the hd, should I purchase the hd version of the app or the same app scale up/down according to the device?

And it would also be a nightmare from marketing point of view, to which version would you point your customers, or request to review app, etc
