一、Qt for Android的配置方法：
- 安装正确版本的Java JDK（经测试，qt 6.7.3版本对应于Java JDK 17），并在环境变量中进行添加，Windows控制台使用命令java --version可验证环境变量是否添加成功并查看安装的Java版本。
- 在Qt creator中进行配置：
2.1 配置JDK位置后，点击设置SDK可以自动下载对应的Android-SDK套件，按照系统引导一直点确定即可。
下载好以后点击SDK管理器，搜索Android emulator勾选应用以安装对应的安卓模拟器。
2.2 点击下载openSSL跳转GitHub仓库，download对应的zip文件，解压到自定义位置，然后回到Qt creator进行位置添加即可。
2.3 在设备中添加安卓设备，架构取决于安装的SDK套件，如果没有可以回到SDK管理器进行下载，我这里选择x86_64，后续编译也是使用x86_64，设备名称不限，其余默认即可。（目标api的选择影响后续的配置）
2.4 添加了安卓模拟器后可以点击启动AVD进行查看，如果无法打开则：
控制面板-卸载程序-启动或关闭Windows功能-打开Hyper-V-重启电脑
打开后模拟器后应该如下图所示：
如下图，在构建套件界面可以看到安卓构建套件已安装完毕。
新建安卓项目，运行即可。（有的人在新建项目进行运行后会提醒需要再下载一个套件，详情可参考网上经验，笔者由于安装过程中没遇到该问题，因此不在此赘述）
二、 遇到的问题及其解决方法：
1. 问题一：

问题分析：Java JDK版本不匹配
解决方法：安装了高版本的Java JDK，将Java JDK 23修改为Java JDK 17
2. 问题二：

Error while building/deploying project AndroidTest (kit: 安卓 Qt 6.5.3 Clang x86_64) When executing step “构建安卓 APK”
问题分析：属性 android:allowNativeHeapPointerTagging 未找到
解决方法：打开 D:\Qt\6.5.3\android_x86_64\src\android\templates\build.gradle 文件，检查并修改以下字段：
android {
compileSdkVersion 31 // 确保这里是至少 API 31
defaultConfig {
minSdkVersion 21
targetSdkVersion 31 // 确保目标 SDK 是 31 或更高
}
}
