错误提示

Error: Your project contains C++ files but it is not using a supported native build system.
Consider using CMake or ndk-build integration. For more information, go to:
 https://d.android/r/studio-ui/add-native-code.html
Alternatively, you can use the experimental plugin:
 https://developer.android/r/tools/experimental-plugin.html

原因：

在 /app/src/main/ 下创建了 jni文件，并创建了Android.mk文件

文件内容

LOCAL_CERTIFICATE := platform
LOCAL_CERTIFICATE := shared

make project  报错

解决建议：在 build.gradle 中添加以下代码

android {
  ........

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