我正在尝试为Android制作一个Qt程序。我已经下载了android Qt包，Android SDK，NDK和JDK，标记了它们文件夹的路径，但是当我尝试为我的设备构建它时，它给出了我的构建错误（我已启用usb调试那里和安装了adb驱动程序）它给了我这个编译输出：

然后它不起作用。他引用了一些build.xml文件，但我的Android SDK完全正常工作，因为我在Android Studio中使用SDK制作了一些程序。所以问题出在Qt。
然后我试图通过提供我自己的清单来解决问题。我对.pro文件进行了一些编辑，但这并没有改变任何内容：

答案 0 :(得分：3)
答案很简单：不要在Qt上使用Android Studio的NDK和SDK包。您只需从官方网站下载单独的软件包（它们稍微低于Android Studio的下载链接）并安装Android SDK软件包和NDK，以及最新版本的JDK。
