Q about Building my game for so many devices


i have already finished my 2D game by using C# but there is a problem:

i want to build my game on ios and android but there are a lot of devices which means a lot of resolution

so how can i solve this problem? so i dont need to stretch or shrink my images?

Have a look to the accepted answer here. Make sure your textures are targetting the highest resolution from the device you are targetting. Will be the ipad resolution. and then apply the matrix scale over it.

any answer please?
