构建后无法打开flutter应用程序
因此，我只是整夜都在混乱，重新安装Android Studio，vScode和Vscode和Flutter，因为我试图为我的应用程序构建一个APK，该应用程序已经准备好了，该应用程序已经准备好向一些朋友进行测试。当我的手机连接到我的计算机时，我可以讨论我的应用程序没问题，所以我认为没什么大不了的，让我们推出APK并炫耀我的工作。这是一场噩梦，而且仍然是一场噩梦。
我遵循了构建Android应用程序的本步骤指南... https://docs.flutter.dev /部署/Android 因此，一旦我终于收到了所有的神秘错误，足以构建一个APK，我就将文件复制到手机上并安装了它。很快就安装了它，并且仍然在弹出窗口上，我看到了2个按钮，闭合并打开，只打开了灰色。我不能打开我的应用程序。
我尝试将TargetsDkversion更改为手机Android版本。我尝试为所有处理器构建所有可能的版本以及AppBundle and APK，而我似乎无法打开一个变体。我有键。
还有其他人构建了Flutter应用程序，但无法打开它吗？我很难过...我为Google Play Prove Protect添加了额外的弹出式弹出窗口，因此我去了并关闭了该功能。我已经将手机处于开发人员模式多年了多年，所以我知道允许未知来源。
它安装了良好，但并未在任何地方创建图标。一旦我退出原始安装弹出窗口，ID就知道它在设备上的唯一方式就是进入设置/应用程序并在此处找到它，而在那里，唯一的选项是卸载和强制停止，也将其弄清楚。因此该应用程序不可用
So I just spend the whole night messing up and reinstalling android studio and vscode and flutter cause I was trying to build an apk for my app that's ready enough to pass out to some friends for testing. when my phone is connected to my computer I can debug my app no problem so I thought no big deal lets push out an apk and show off my work. What a nightmare this has been and still is.
I followed this step by step guide to building an android app... https://docs.flutter.dev/deployment/android
So once I finally got all the mystery errors out enough for it to build an apk I copied the file over to my phone and installed it. Well soon as it installed and still on the pop up I see 2 buttons, Close and Open, only open is greyed out. I cant open my app up.
I tried changing the targetSdkVersion down to my phones android version.I tried building out every possible version and appbundle and apk for all the processors and I just cant seem to get a variant to open. I have the key.properties file all linked up, I used the keytool like in the guide.
Has anyone else build out flutter app but cant open it? I'm stumped... The first few attempts I was getting extra popups for googles play protect so I went and turned off that feature. Ive had my phone in developer mode for years now so I know unknown sources are allowed.
It installs fine, but doesnt create an icon anywhere to be used. Once i exit out of the original install popup the only way Id know it was on my device is to go into settings/apps and find it there, and in there the only options are uninstall and force stop which is also greyed out. So the app is unuseable
