一直用QT5.5.1，周末无事，升级到5.14，发现各版本的NDK都无法完美运行，有换成5.9，还是各种出错
最后发现，QT版本与NDK版本有兼容问题，具体原因未知，只能按网上大神的推荐去摸索安装使用
完美运行并编译出APK文件的版本如下：
1.NDK下载：android-ndk-r19c-windows-x86_64.zip
https://dl.google.com/android/repository/android-ndk-r19c-windows-x86_64.zip
测试后发现，r18和R19能完美匹配QT5.12.0
https://dl.google.com/android/repository/android-ndk-r18b-windows-x86_64.zip
NDK各版本下载地址如下

2.SDK下载 android-sdk_r24.1-windows
http://tools.android-studio.org/index.php/sdk
3.JDK
下载JDK1.8（SDK只支持JDK1.8）:亲测JDK-8u191、JDK-8u201、JDK-8u241可以无错运行

4.QT5.12.0
https://iso.mirrors.ustc.edu.cn/qtproject/archive/qt/5.12/5.12.0/qt-opensource-windows-x86-5.12.0.exe
具体配置就不说了。以上版本完美运行，编译不出错。
