Reproducible Demo

• react-native init test58
• cd test58
• react-native run-android

Any idea what is wrong here ? The new release ? My environment ?

I am seeing this issue on RN 0.59.2 I freshly installed Android Studio 3.3.2 along with sdk, emulator etc. I run react-native init, and run-android and get the FATAL EXCEPTION: OkHttp Dispatcher error.
