android - 单击登录按钮后，React 本机发布签名的 apk 文件崩溃

问题描述

我使用以下链接创建了我的应用程序的 APK 文件。

https://facebook.github.io/react-native/docs/signed-apk-android#docsNav

成功安装，一旦我点击登录按钮，它就会显示“不幸的是，应用程序已关闭错误”。我尝试创建其他项目的 APK，它工作正常。但是，在这个项目中，它崩溃了。

创建项目后，我将项目名称更改为 string.xml 文件。这有什么问题吗？甚至尝试保留以前的名称，但我的问题没有得到解决。 我的 package.json 文件是

{
  "name": "awsUpload",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "aws-sdk": "^2.395.0",
    "link": "^0.1.5",
    "react": "16.6.3",
    "react-native": "^0.58.3",

    "react-native-material-dropdown": "^0.11.1",
    "react-native-router-flux": "^4.0.6",
    "uniqid": "^5.0.3"
  },
  "devDependencies": {

    "react-test-renderer": "16.6.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

我的包裹有问题吗？

我的按钮文件代码是
