Doesn't do anything.

In a relative layout. Text size stays the same.

    <me.grantland.widget.AutofitTextView
        android:id="@+id/tvMessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/lButtons"
        android:layout_below="@+id/barcode_scanner"
        android:layout_margin="10dp"
        android:gravity="center"
        android:textSize="24sp"
        ads:minTextSize="10sp"
        />

Looks like you need to set the maxLines to get it to work. Now I see that using a margin the text does not fit properly.

Yeah, that's required. I'll be closing this since it's resolved.
