Question

IDE: Android Studio

1. Create new project
2. Copy .jar of appcompat to by /lib/
3. Set dependencies in project settins
4. Add compile "com.android.support:appcompat-v7:18.0.+" to build.gradle

5. Add follow code:

   public class MainActivity extends ActionBarActivity {

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   
       ActionBar actionBar = getSupportActionBar();
       actionBar.setTitle("hello");
   }
   

AND... Nothing. Get next error:

"Gradle: A problem occurred configuring project ':MyApplication'.
> Failed to notify project evaluation listener.   > Could not resolve all dependencies for configuration ':MyApplication:_DebugCompile'.
  > Could not find any version that matches com.android.support:appcompat-v7:18.0.+.
