You will be ended up with this error, If your libraries/modules uses different minSdkVersion

files ans sync.
If it doesn't solves the problem go through your gradle console to and make required changes as per the error shown.
Note : While compilation, your minSdkVersion and targetSdkVersion in AndroidManifest.xml will be overridden by what you have mention in your build.gradle files.
