我认为它与以下网站的NDK应用程序链接到平台库有关。

I think that it is related to "NDK Apps Linking to Platform Libraries" of the following site.

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

根据这个，libtango_client_api.so是私人平台库？

According to this, "libtango_client_api.so" is "private platform library"?

或者我的配置文件中有错误吗？

Or is there a mistake in my configuration file?

我不知道如何修复它，所以我可以改善它。我怎样才能提高警告？请帮帮我。

I do not know how to fix it, so I can not improve it. How can I improve my warning? please help me.

顺便说一下，配置文件与Tango示例项目几乎相同。

By the way, the configuration file is almost same as the Tango sample project.

推荐答案

不知道原因，但此错误仅在调试模式下发生，而不是在发布模式下。
因此，解决方法在发布模式下运行您的应用程序。

Don't know why, but this error occurs only in debug mode not in release mode. So as a workaround run your application in release mode.
