Icon is created then disappears
I included "compile 'com.mikepenz:iconics:1.0.1@aar'" in my gradle config and then tried to used both IconicsTextView and IconicsImageView in a layout. The icon (I tried different ones) appears briefly and then disappears. In case of a conflict, I tried both with and without your Material Drawer library.

Example layout:

``` xml
<RelativeLayout
        android:id="@+id/card_border"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/accent"
        android:gravity="fill_vertical"
        android:paddingBottom="8dp"
        android:paddingLeft="16dp"
        android:paddingRight="16dp"
        android:paddingTop="8dp">
        <android.support.v7.widget.AppCompatTextView
                android:id="@+id/txtGame"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignParentStart="true"
                android:text="CE"
                android:textColor="@android:color/white"
                android:textIsSelectable="false"
                android:textSize="12sp"
                android:typeface="sans"/>
        <com.mikepenz.iconics.view.IconicsTextView
                android:id="@+id/iconAlert"
                android:layout_width="16dp"
                android:layout_height="16dp"
                android:layout_centerInParent="true"
                android:text="{gmd-error}"
                android:textAlignment="center"
                android:textColor="@android:color/white"
                android:textSize="16sp"/>
        <android.support.v7.widget.AppCompatTextView
                android:id="@+id/txtLevel"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentEnd="true"
                android:layout_alignParentRight="true"
                android:singleLine="false"
                android:text="***"
                android:textColor="@android:color/white"
                android:textIsSelectable="false"
                android:textSize="12sp"
                android:typeface="sans"/>
</RelativeLayout>
```
