best touchscreen resolution (pixels/mm)

 Does anyone know the best touchscreen resolution for Android?  Most
likely there would be a sweet spot for this.  The higher the
resolution the more data which could cause a bottleneck for data flow
and the low the resolution the worse the accuracy is.  I would imagine
this to be in the units pixels per millimeter.

 Some that is at least the same resolution as the screen should be
sufficient.  Very few things -- certainly nothing that is part of the
standard platform -- is going to do much useful with sub-pixel touch data
(though we do report it in the APIs).

1. How to get the used memory (ram) by a task/process?

Hi everybody,

I have a List of RunningTasks:

        ActivityManager am = (ActivityManager)getSystemService
        List<ActivityManager.RunningTaskInfo> list = am.getRunningTasks

and i can to get the app icon of each Task (i.e.):

        pm = getPackageManager();

Now, how can I get the memory used by a Task? I don't find nothing
like that in the api reference.
The class RunningTaskInfo has not nothing about memory used.

Any idea?

Thanks in advance,
