Hello, I'm trying to add the Facebook SDK and Firebase to my project in Android studio and to do that the project has to be migrated to Gradle. I migrated it but when I try to run it I receive the following error: 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. I'm not sure which direction to proceed and what should I do from those links. If anyone did anything like this, please help me. Thanks.
