I replaced all "compile" to "implementation" in the build.gradle (Module: app) but I can't know how to change "compile" to "implementation" in "compileSdkVersion" to solve this error message (or look the screenshot below):
Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'. It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html
I need your help. Thank you!
