ReferenceError: Can't find variable: __fbBatchedBridge
I generally see this when the packager hasn't started. Ensure that is running by running react-native start
I had the same issue while using Visual Studio Android Emulator. When the red screen shows up type in the command line
adb shell input keyevent 82This will trigger the shake event and launch the dev menu
Then hit Dev Settings > Debug server host & port for device and enter <your ip adress>:8081. If for some reason you cannot type in the field you can trigger the text action in the command line by using
adb shell input text <your ip adress>:8081
