[React Native][Android only] Standalone app doesn't work after 0.15.4

[jhen0409]

Use standalone app for React Native on Android, it still showing Connecting to React....

Just tracking for commits, I can confirm 0.15.3 works fine, it looks broken by 0.15.4 change. (Just one change: #415)

Thanks for tracking this down! It looks like the standalone app will connect fine if you're debugging js remotely, but not if the js is running in-app (at least that's what I see w/ the ios simulator). I'll investigate

Hmm so I'm seeing it working for me, both in android & iOS. If you reload the standalone app while the react-native app is running, does it start working for you @jhen0409?

I tried again, looks like it only can be reproduce when I start app with debug remotely mode, otherwise it works fine:

I'm tracking for this, looks like the problem is related to requestIdleCallback, the callback never invoked in debugger worker, need to know why the worker has no idle time. :\

There may be some potential problems in RN for Android, not here, sorry for wasted your time @jaredly. 😅
