问题描述

最近升级了Flutter版本到3.3.2,然后用命令:flutter build apk 打包后,发送到手机上安装提示解析软件包出错

问题出现的环境背景及自己尝试过哪些方法

compileSdkVersion 32
minSdkVersion 29
targetSdkVersion 29

我的手机是Android 11

怀疑是Android API Level版本不对,但查了一下Android 11 的 API Level 是30,而我设置的minSdkVersion是29,应该不是这个问题。

但使用 flutter install 命令 ADB 方式安装到手机正常。

那么是因为签名问题吗?不是很清楚。。。但我检查了签名的相关配置,没问题

搜索了一下在CSDN上看到解决方法。发现是手机系统设置问题,MIUI的问题,在开发者选项中关闭MIUI优化开关即可正常安装了,之前是解决Flutter 3.3.2的问题关闭再开启过一次MIUI优化开关,现在得关闭MIUI优化开关才行。。。。具体MIUI优化开关为什么会这样不得而知。。
