Preventing hardware back button android for React Native

Question

I want to prevent the user from going back to the previous screen. So I added code, but this does not work. Are there any solutions for this? The alert pop up is seen but \"

Answer 1

using the BackHandler from react native worked for me. Just include this line in your ComponentWillMount:

BackHandler.addEventListener('hardwareBackPress', function() {return true})

it will disable back button on android device.
