android - 使用 Qt for Android 启动时，Android 应用程序崩溃

Question

我正在qt 的网站上尝试这个示例应用程序。它构建时没有错误，当我尝试在装有 Android 8.1.0 的三星 J7 上运行时，出现白屏，然后应用程序崩溃。在 Qt 创建器中，此消息显示为应用程序输出

"org.qtproject.example.androidTest4" died.

由于我之前没有在 Qt 上开发 Android 的经验，所以我不知道如何解决这个问题。Qt for Android 中的设置具有最新的 Android SDK、Android Studio 文件夹中的 JRE 和 Android NDK 版本 17。感谢任何指导。
