Android : Android Toolbar "Padding"

I implemented the new android l toolbar but there is this odd border or padding around it, I don't know why it's there and I would like to get rid of it. Here is the code for the toolbar:

 <android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#4432aa"
    android:contentInsetStart="0dp"
    android:contentInsetLeft="0dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    />

Any help would be appreciated.
