Problem Android Studio

Hi all!

I'm trying to start a course with Android Studio 2.2.1, but when I create a new project I come upon the error message:

failed to resolve com.android.support appcompat-v7 29

Also my Mainactivity.java gives me the error:

Method does not override method from superclass.

I've tried to add the Maven URL, but with no luck.

When I try to rebuild the project I get:

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApkCopy'.
> Could not find any version that matches com.android.support:appcompat-v7:29.+.
Versions that do not match:
26.0.0-alpha1
25.3.1
25.3.0
25.2.0
25.1.1
+ 31 more
Required by:
DemoAppTwo:app:unspecified

Does anybody know a solution for this, so that I can start learning to code in android please?
Thanks in advance!

Kind regards,
KevinDP
