QtCreator注意NDK版本

关于Qt for android构建的Failed to GetFullPathName错误

Java版本问题：Your build is currently configured to use Java 17.0.6 and Gradle 5.6.4.

修改JAVA的版本

Java的安装一般路径

C:\Program Files\Android\jdk\jdk-8.0.302.8-hotspot\jdk8u302-b08

C:\Program Files\Java\jdk-17

QtCreator输出多个CPU类型代码设置

注意QTCreator对应的NDK版本

Qt Creator 4.9.0 (Enterprise) 用android-ndk-r19c

qtcreator4.11     用android-ndk-r20b

关于Qt for android构建的Failed to GetFullPathName错误

最近在做Qt for android的项目的过程中，运用Qt的自带的例子编译一个qt for android的APK，发现了一个编译错误如下：

刚开始也不知道啥问题，然后翻译了一下Failed to GetFullPathName，发现了是不能获取路径的问题，然后就网上的百度了一下，刚好看到了有位大佬的解决方法，究其原因还是这个构建文件夹的路径和文件名称太长了，导致编译的时候编译器无法获取到准确的路径名，所以可以将构建的路径选择到别的文件夹去。

我之前的构建目录：

然后就报错，后面将方框里面的构建目录改成了G:\QMLobject 目录下  成功的解决了这个问题
