While trying to run my code, which is include C++ files I get the following error -

Error:(32, 2) error: This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

How it can be solved? This is my first project that involved with C++ files.

You must enable "the -std=c++11 or -std=gnu++11 compiler options."

Learning C++ on Android is a very bad idea. Anyway, you must somehow make your IDE pass the correct flags to the compiler in order to use C++11 features and/or use a compiler for which C++11 is no longer experimental. I hear there's some "Customize C++ Support" button or dropdown menu somewhere in the UI which can do that for you.

I know i have to use -std=c++11 or -std=gnu++11 but how can i config that?

There are multiple ways of building native code from Android Studio, and I don't see any mention of which one you're using. If you've got an Android.mk file you could add any flags you want in there to LOCAL_CPPFLAGS. Otherwise you probably need to use some sort of cppFlags property in your build.gradle file.

I have rebuild my project and use C++11 instead of ToolChain Default in Customize C++ Support page. I think it is a dirty way for solving this problem.

Maybe 'ToolChain Default' is not the perfect way to present one of the choices, but this is the clean way to deal with this problem. C++ has different not exactly compatible 'modes', e.g. C++11 and C++13, and it is your responsibility to choose the appropriate dialect.

In app's build gradle under android -> defaultConfig you can add / change the following

externalNativeBuild {
        cmake {
            cppFlags "-std=c++11"
        }
    }
