Issue while previewing the layout xml in Android Studio
I have added the image to the custom component using

``` java
new IconicsDrawable(context)
                    .icon(GoogleMaterial.Icon.gmd_keyboard)
                    .color(getResources().getColor(R.color.button_default))
                    .sizeDp(R.dimen.default_icon_size)
```

Tho, **I am able to see the icon in the actual application**, the Android Studio previewer complains that the `font/material-design-iconic-font-v2.2.0.ttf` could not be found.  [So I added the font `material-design-iconic-font-v2.2.0.ttf` explicitly to my `assets/fonts`, along with the gradle dependency](https://github.com/code-mc/material-icon-lib#step-0). After this change, I get the following exception in the Studio previewer

``` java

Here is my gradle configuration

``` gradle
compile 'com.mikepenz:iconics-core:2.2.0@aar'
compile 'com.mikepenz:google-material-typeface:2.2.0.1@aar'
compile 'com.mikepenz:fontawesome-typeface:4.4.0.1@aar'
compile('com.mikepenz:materialdrawer:4.5.1@aar') {
    transitive = true
    exclude group: 'com.mikepenz', module: 'iconics-core'
}
```

and this is how I am plugging the wrapper into activity

```
@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(CalligraphyContextWrapper.wrap(IconicsContextWrapper.wrap(newBase)));
}
```

Are there steps that I need to follow to make sure that preview works?
