I find note in documentation https://developer.android.com/ndk/guides/cpp-support#c_runtime_libraries :我在文档https://developer.android.com/ndk/guides/cpp-support#c_runtime_libraries 中找到注释:
libc++ is not a system library.
libc++ 不是系统库。 If you use libc++_shared.so, it must be included in your APK.
如果您使用 libc++_shared.so,它必须包含在您的 APK 中。 If you're building your application with Gradle this is handled automatically.
如果您使用 Gradle 构建应用程序,则会自动处理。
I understand that it building incorrectly, because my APK don`t include library我知道它构建不正确,因为我的 APK 不包含库

I refactored my Android.mk GSTREAMER_PLUGINS
field and add GSTREAMER_EXTRA_LIBS
.我重构了我的 Android.mk
GSTREAMER_PLUGINS
字段并添加GSTREAMER_EXTRA_LIBS
。 I replaced categories with specific plugins that using in my project and it solve my problem.我用我的项目中使用的特定插件替换了类别,它解决了我的问题。
...
GSTREAMER_PLUGINS := coreelements udp rtpmanager rtp opengl playback
GSTREAMER_EXTRA_LIBS := -liconv
...
Looks like some plugins in categories have a bugs看起来类别中的某些插件有错误
Thank you @NikolayKhilyuk for trying to help me谢谢@NikolayKhilyuk 试图帮助我
It looks like targets "client"
issue.看起来像
targets "client"
问题。 Try to remove it at all or specify NDK_APPLICATION_MK
:尝试完全删除它或指定
NDK_APPLICATION_MK
:
...
externalNativeBuild {
ndkBuild {
...
targets "client"
arguments "NDK_APPLICATION_MK:=Application.mk"
...
}
}
}
