不再支持Android NDK APP_STL gnustl_shared

Question

/home/ndqa/opt/android-sdk/ndk-bundle/build/core/add-application.mk:178:***不再支持Android ndk:APP_STL gnustl_shared。请切换到C++_Static或C++_Shared。有关更多信息，请参见https://developer.android.com/ndk/guides/cpp-support.html。.住手。

我的机器是Ubuntu18，它有android SDK，NDK。请帮我解决这个问题。谢谢大家！

更新如果我用C++_static或C++_shared替换gnustl_shared，它会显示更多错误：

1. 在文件application.mk
中将 app_stl:=GNUSTL_STATICAT切换到 C++_STATICAT或 C++_shared

APP_STL:=C++_STATIC

对于ndk-build，请删除设置NDK_TOOLCHAIN或NDK_Toolchain_Version的行。

对于cmake，删除行设置android_toolchain。

对于独立的工具链，请使用clang/clang++二进制文件，而不是gcc/g++。

对于其他生成系统，请询问该生成系统的所有者。
