Got JS Exception: ReferenceError: Can't find varia

           在Android Studio上首次運行（react-native）AwesomeProject（導入android便可），出現了一下問題

                                      Got JS Exception: ReferenceError: Can't find variable: __fbBatchedBridge

解決方案：

在命令提示框的工程目錄下 react-native start(打開服務器，保持開的狀態)，

如果服務器已打開則輸入react-native run-android

而後cmd中adb shell input keyevent 82

虛擬機會出現，選擇Reload JS 便可更新修改後的狀態，不須要從新run。

這只是這次問題的解決方法。
