java - 运行 Tango API 会在库上显示一个警告对话框

Question

我正在通过 Tango 开发 AR 应用程序。该设备是 ZenfoneAR (Android 7.0 Nougat)。

我改进了示例项目并开发了一个应用程序。但是，当启动应用程序时，将显示以下警告消息。

对话消息

我认为这与以下站点的“NDK Apps Linking to Platform Libraries”有关。

https://developer.android.com/about/versions/nougat/android-7.0-changes.html#ndk

据此“libtango_client_api.so”是“私有(private)平台库”？

还是我的配置文件有误？

我不知道如何修复它，所以我无法改进它。我怎样才能改进我的警告？请帮助我。

顺便说一句，配置文件几乎与Tango示例项目相同。

不知道为什么，这个错误只发生在debug模式下，release模式下没有。因此，作为一种解决方法，请在 Release模式下运行您的应用程序。
