Can't run Examples/BarcodeScanner: "undefined is not a function" #63

Closed iivvoo closed 7 years ago

iivvoo commented 7 years ago

The BarcodeScanner example does not work for me - not in an AVM or on an actual device. In both cases I get an error similar to

java.util.concurrent.ExecutionException
java.lang.RuntimeException:
TypeError: undefined is not a function
(evaluating '(bridgeConfig.remoteModuleConfig||[]).forEach')
...
createReactContext
ReactInstanceManagerImpl.java:911
access$700
ReactInstanceManagerImpl.java:100
...

(error typed not copied, may contain typo's)

I'm currently evaluating react-native as a platform for a simple app with qr code scanning functionality so I know very little about how to further debug this.

Turns out I ran "react-native start" from the wrong (different) project. The error is as cryptic as you'd expect from a JS code base :)
