Jni报错： Error: Your project contains C++ files but it is not using a supported native build system

jni初始配置参见 https://blog.csdn.net/mabeijianxi/article/details/68525164

我用的第二种方法，报错Error: Your project contains C++ files but it is not using a supported native build system

解决办法:

在文件build.gradle(Module:app)里的buildTypes类中添加方法：

sourceSets {
    main {
        jni.srcDirs = []
    }
}

最终效果为：

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    sourceSets {
        main {
            jni.srcDirs = []
        }
    }
}

问题解决！
