reload not working in android, works in ios. what am i doing wrong?

[muhammad-gani]

this is my configuration

Reloader.configure({
check: 'firstStart', // Only make an additional check the first time the app ever starts
checkTimer: 3000, // Wait 3 seconds to see if new code is available on first start
refresh: 'startAndResume', // Refresh to already downloaded code on both start and resume
});
