I'm new to android studio. I've created a new project with android studio, when I want to run it I've got this error :
Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
> Could not find com.android.support:appcompat-v7:21.+
Searched in the following locations:
https://jcenter.bintray.com/com/android/support/appcompat-v7/21/appcompat-v7-21.pom
https://jcenter.bintray.com/com/android/support/appcompat-v7/21/appcompat-v7-21.jar
Required by:
myappname:app:unspecified
one thing that surprised me is that I opened this link:
https://jcenter.bintray.com/com/android/support
but this link is incorrect!
what is the cause of this error? I have android support library installed:
