Qt for Android 和 ARCore 应用程序冲突

Question

我正在尝试使用 Qt 为 Android 创建 ARCore 应用程序。

我能够运行 ARCore 示例 (hello_ar_java,hello_ar_c) 和 Qt 示例 (jnimessenger)。 但是两者结合在一起，它就会崩溃。

我从Qt JNI Messenger Example开始。 我从build.gradle模板目录（~/Qt/5.15.0/android/src/android/templates/build.gradle）添加了 build.gradle。 然后我将implementation 'com.google.ar:core:1.18.0'添加到dependencies 。

dependencies {
    implementation 'com.google.ar:core:1.18.0'
    implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
}

但它因这个错误而崩溃。

我想知道为什么这种依赖会破坏最初工作的 Qt。（我是 Android 的初学者。）

我做错什么了吗？ 有没有办法同时使用 Qt 和 ARCore？

• Qt:5.15.0
• QtCreator:4.12.0
• AR核心：1.18.0
• Android SDK：从 Android Studio 4.0.1 安装
• NDK：21.3.6528147
• MacOS Catalina:10.15.5
• Android 设备：像素 3a Android 10

谢谢您的帮助！

我不明白逻辑，但我已经解决了问题。

我选择了 arm64-v8a。 (项目>构建步骤>ABIs)
