javascript - 通过 expo 构建的 apk 未安装在 Android 上

Question

我研究了如何使用react-native开发android应用程序。我制作了像“Hellow World”这样的简单应用程序，并在世博会上构建它。

从命令行我运行:

exp build:android
We've built a brand new CLI for Expo!
Expo CLI is a drop in replacement for exp.
Install: npm install -g expo-cli
Use: expo --help

应用程序构建得很好。我从 Expo 网站下载了 apk，并尝试在 Android 上安装。安装时，我收到如下错误消息:

Play Security 找不到开发者信息。来自未知开发者的应用程序可能不安全。

注意问题。如何确保我的应用程序安全？我找不到这方面的信息。这样就可以在不禁用android保护的情况下安装它。

我的 app.json 看起来像:

{
  "expo": {
    "name": "wtf",
    "slug": "wtf",
    "privacy": "public",
    "sdkVersion": "34.0.0",
    "platforms": [
      "ios",
      "android",
      "web"
    ],
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": [
      "assets/*"
    ],
    "ios": {
      "supportsTablet": true
    },
    "android": {
      "package": "com.wtf.wtf"
    }
  }
}

等待应用程序在 Android 上安装。

在手机设置中，您应该能够选择一个选项以允许来自不受信任来源的安装。然后它应该给你一个像“仍然安装”这样的选项
