I'm trying to use MAT for Android development. II'm not clear whether the histogram section is showing only live objects when the dump was taken, or both live and previously allocated/freed objects.

Can someone please clarify? And if it's both live + historical, then is there a way to get it to show only live objects? Many thanks.

I have no experience with the Android dumps, but in general hprof has no historical data.
We see however (in hprof dumps from other VMs) a small ammount of objects, for which there are no reference chains from the GC roots.
MAT does remove the unreachable objects itself by default.

Have a look at our wiki description here:
You can probably try out if keeping changing the settings make any difference.

Hope this helps.
