The problem

  

Gradle sync failed: Failed to find target with hash string   'android-27' in

indicates that you do not have version 27 of the SDK installed for this reason your project can not be built, go to SDK Manager

Select version 27 and click on "apply":

in this way the installation will be done:

In my case I had this Manifest tag that gave that error, which was from an example of search diccionary   <uses-sdk android: minSdkVersion = "15" android: targetSdkVersion = "27" /> , Then delete it and synchronize and it worked fine. Then update that label as it should go 

    <uses-sdk android: minSdkVersion = "15" android: targetSdkVersion = "27" />
