我正在使用React Native v 0.62.2,并且正在尝试使我的项目也在Android上运行。到目前为止,我一直专注于iOS的开发,因此从未运行过Android应用程序。现在我想运行android应用程序,但是在启动屏幕显示以下堆栈跟踪后,该应用程序在启动时崩溃:

我在网上搜索了解决方案或至少有提示,但不幸的是没有找到任何解决方案,甚至没有任何解决此问题的想法。
有谁有想法吗?另外,如果您需要任何其他信息才能回答问题,请告诉我。
非常感谢!

最佳答案

对于所有也在这个问题上苦苦挣扎的人-经过长时间的研究加上反复试验,我终于把它解决了。
看来此问题实际上与OK HTTP有关。使我开始运行的步骤如下:

  • 启用MultiDex,但还要继续关注AndroidX解决方案(因为我使用的是已经利用AndroidX的最新版React Native),如以下答案所述:

  • 请按照以下注释中给出的说明添加ProGuard文件:https://github.com/facebook/react-native/issues/9043#issuecomment-298832659
  • 关于android - React Native应用程序在Android上启动时崩溃:找不到类 “com.facebook.react.devsupport.DevSupportManagerImpl”,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/63539691/
