DashPathEffect does not work when singleline is enabled
<p>When i 
<br>- disable setSingleLine(false), 
<br>- The dashed line, that i set using DashPathEffect, is nicely drawn as expected</p>

<p>But
<br>- enable setSingleLine(true), 
<br>- the DashPathEffect i have set for my paint object does not work. No line is being drawn. 
<br>- If i remove the path effect, the solid line is able to draw. Why???</p>
