自从我开始使用Expo编写React Native时，我一直在与Expo应用一起使用iOS物理设备。 我从来没有遇到过任何重大问题。
现在，我想开始在Android上修复任何错误，但是当在我的Android物理设备上运行Expo应用程序时，Expo应用程序在下载捆绑包时崩溃（关闭）。 它不会将任何错误打印到我的控制台中，所以我甚至不知道从哪里开始...
这是我的app.json：
{
"expo": {
"name": "PointoUserApp",
"slug": "PointoUserApp",
"version": "1.0.0",
"platforms": [
"ios",
"android",
"web"
],
"orientation": "portrait",
"icon": "./assets/Images/icon.png",
"splash": {
"image": "./assets/Images/splash.png",
"resizeMode":"contain",
"backgroundColor": "#ffffff"
},
"updates": {
"fallbackToCacheTimeout": 0
},
"assetBundlePatterns": [
"**/*"
],
"ios": {
"bundleIdentifier": "com.meretc23.PointoUserApp"
},
"android":{
},
"web": {
"favicon": "./assets/Images/favicon.png"
}
}
}
请注意，在Android下它是空的，因为我不知道需要什么。
以下是我的 package.json 文件。

教训：如果你想在iOS和Android上运行应用程序，在你的应用程序太大以至于不知道问题来自哪里之前，一定要同时监控两者。
