我尝试在针对android的react-native应用程序中使用Firebase数据库 我遵循这个tutorial。
我使用这个本机反应版本：
react-native-cli: 2.0.1
react-native: 0.42.0
在package.json中：
"firebase": "^3.7.0",
在开发模式下的模拟器或真实设备上，一切都很好但是当我构建一个发布版apk时，它会在应用启动时崩溃
我做了很多测试，问题出在firebase导入
上在logcat中，我有这个，有什么想法吗？

降级到firebase 3.6.5似乎已经为我修复了

好消息！有用 ！ 我初始化一个新的react-native项目并安装最后的firebase版本，现在是3.7.1！ 一切都很好
感谢您的帮助
