Set resolution for Android and IOS

Hello friends! I would like to know how to set the resolution of my game for Android and iOS . I will be very grateful for any help! I’m using google translator , any error sorry. See you!!!

The resolution isn’t directly set. You can use r.MobileContentScaleFactor in the device profile to control the scaling. 0 will use native resolution. 1 will use 1280x720 or 720x1280 corrected for the aspect ratio of the native device for the orientation. Anything else will be multiplied by this value.
