Error creating the app!

Hello, I have this error on my gradle build, help me please

Error:Execution failed for task ':app:preDebugAndroidTestBuild'.

Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

The best solution I found for this problem was to update the compileSDKVersion to '27', and update any support dependencies in your gradle to 

com.android.support:____-v7.27.0.1

There is an inconsistency between your testImplementation declarations and your implementation declarations. Updating the SDKVersion as well as your support declarations resolves it.
