I am facing issue during creating apk on android studio. please guide me what should i need to do. steps that i have already done. 1- android ndk downloaded. 2- CMake downloaded from sdk tool. Error description that i am facing. Error:Execution failed for task ':app:compileDebugNdk'. > Error: Your project contains C++ files but it is not using a supported native build system. Consider using CMake or ndk-build integration with the stable Android Gradle plugin: https://developer.android.com/studio/projects/add-native-code.html or use the experimental plugin: http://tools.android.com/tech-docs/new-build-system/gradle-experimental.
