I want to prevent android phone from going to sleep using my code?

I want to prevent android phone from going to sleep using my code? How to do that please help.

try this

function Start (){
Screen.sleepTimeout = SleepTimeout.NeverSleep;

}

I would add that if you want to revert it to the normal state you’ll have to use this: Screen.sleepTimeout = SleepTimeout.SystemSetting;

It appears you can set iPhoneSettings.screenCanDarken to false to achieve this at the moment.
