Android support Library v7 appcompat

Question

i've got a problem with the Android v7 Support Library. I want to use Android Material Design on Android Version 4 and above, so I have to use the Support Library v7 appcompat. For Development i'm using IntelliJ IDEA 14.1.4

The way i included the Library: Project Structure Libs

Project Structure Modules

If i compile and run my Project, this error occures:

The Xml-Document, where the error occures:

    <?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="128dp"
        android:background="#DDD">

</android.support.v7.widget.Toolbar>

I'm working on this for hours. I hope someone can help me. Thanks in advance

(Sorry for spelling- and grammatical errors)

Edit:

I added the libs like described in the other Question. I have it now like this: Project Structure Library Module

Project Structure Main Module

But still the same errors :l

Can you show your gradle build file ?? – m0rpheu5 Jul 15 '15 at 09:57 — m0rpheu5, Jul 15 '15 at 09:57

add this in your build.gradle(Module:app) dependencies:

compile 'com.android.support:appcompat-v7:21.0.3'

and then sync your project

it will add the library automatically
