for Maven users wrong dependency
I have maven project (instead of gradle) but google-material-typeface package its have wrong dependency to Group:Android-Iconics and artifact:library-core you can check here in Compile Dependencies:
http://mvnrepository.com/artifact/com.mikepenz/google-material-typeface/2.2.0.1
Maybe its obsolete I have include the new one Group:com.mikepenz artifact: iconics-core
 Its need to exclude it in my pom.xml to compile the project

``` xml
<dependency>
            <groupId>com.mikepenz</groupId>
            <artifactId>iconics-core</artifactId>
            <version>2.5.5</version>
            <type>aar</type>
        </dependency>

        <dependency>
            <groupId>com.mikepenz</groupId>
            <artifactId>google-material-typeface</artifactId>
            <version>2.2.0.1</version>
            <type>aar</type>
            <exclusions>
                <exclusion>
                    <groupId>Android-Iconics</groupId>
                    <artifactId>library-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
```
