构建的世博会应用程序在启动时崩溃:找不到类"host.exp.exponent.taskManager.ExpoHeadlessAppLoader“

Question

当我试图通过Expo运行使用React Native构建的应用程序时，它在闪屏上崩溃。如果我在真正的设备上通过expo应用程序启动它，或者通过模拟器启动它，它就运行得很好。Logcat给出了错误：

 W/System.err: Caused by: java.lang.ClassNotFoundException: Didn't find class "host.exp.exponent.taskManager.ExpoHeadlessAppLoader"

我找不到关于此错误消息的任何信息，但我似乎读到这些类型的问题与package.json文件有关。我的是这样的：

    {
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web",
    "eject": "expo eject"
  },
  "dependencies": {

  },

        }
      }
    }
  },
  "private": true
}

解决了！事实证明，该错误消息与崩溃无关。我把API钥匙放错地方了。将它从package.json迁移到app.json解决了我的问题。
