Image sizes for android and iOS in react-native

问题:

While making iOS Apps, we generally used to supply @x,@2x,@3x images. And based on my knowledge in case of android, there was some approx six different sizes

I have started working on react-native and came across the image issue.

My Question are: Do I need to provide images with all different sizes (i.e. approx 6-7 image sets by combining iOS and android) Or only 1 image and rest will be taken care internally? Will it look blurred on higher resolution phones?

Thanks.

You still need to provide multiple images. According to the Images documentation, if you are using an image named check.png, you also have to include [e-mail] and [e-mail].

Quoting:

The packager will bundle and serve the image corresponding to device's screen density. For example, [e-mail], will be used on an iPhone 7, [e-mail] will be used on an iPhone 7 Plus or a Nexus 5. If there is no image matching the screen density, the closest best option will be selected.
