By adding Master/Detail Activity in android Studio throws an error

[Marileena13]

I have just created a project and added an activity Master/Detail Activity. On building the app following error occurs:

Error:Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve javax.annotation:javax.annotation-api:1.2.

Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve javax.annotation:javax.annotation-api:1.2.
