Description

i have a native app need to intergrate RN in it. I update RN version to 0.57.3, i cannot load bundle from url when i press Dev's reload button. It didnt load any view. Like this:

Wait a long time, it still didnt show anything.But it can load latest bundle when press R in IOS , only android didnt. I tried to set my host ip in Simulator ,also didnt work.
In android, i see some log at logcat :

my package.json:

So I decided to reduce my RN's version to 0.55.4.
All is normal! Android can load bundle from Dev's reload button. I guess the problem only occurs in RN 0.57. I hope to know why I cannot load bundle in android. Please tell me.

Same issue, In Android, it cannot load js bundle from Dev reload button with RN 0.56+, but it works perfectly well with RN 0.55.
My RN version is 0.56.0, now in Android the debug pkg is broken, and I can only package a release pkg to continue development. It has caused a lot of inconvenience.

@haipengz I tried to "react-native init Demo", android can load js bundle. Demo project is "react": "16.6.0-alpha.8af6728" and "react-native": "0.57.3", it works perfect! Now i confuse about the broblem very much. Maybe not related to the RN version.

@jonatslab it already has "babel-preset-react-native": "4.0.0".

I am glad your issue is resolved @sunny635533. Reproducing brownfield setups (integration into native apps) isn't something we can easily make.
