what functionality does setting the PARENT_ACTIVITY in the manifest file provide?
<p>what functionality does setting the PARENT_ACTIVITY in the manifest file provide?
I played around with it, and from my experience, it doesn't seem to effect the back button functionality (but I could have done something wrong).
Does anyone one know what functionality(ies) this attribute effects? </p>

<p>UPDATE @shoerat: 
TFM is very vague and as I said it didn't seem to affect the back button for me. I removed the parent property from one of my activities and ran my app, and the back button still worked just as before. So this leaves me curious beyond the point of what the manual provides.  </p>
