Answer 1

In the android documentation for v7 appcompat is a note:

Note: This library depends on the v4 Support Library. If you are using Ant or Eclipse, make sure you include the v4 Support Library as part of this library's classpath.

I think thats your problem since you have comment out the line in your gradle:

   // compile "com.android.support:support-v4:18.0.+"

Add the line again and try to compile the project.

Also i see no com.android.support:appcompat-v7:21.0.0 line in your gradle
