I have a simple list view with some check boxes in an alert dialog. I need to option to add a select all/none but you can't bring up the menu in an alert dialog, and I want to do this function from a button. From what I've seen any kind of button (positive, neutral, and negative) all close the dialog regardless.
So, is this possible? ...

As far as I can see, the latency() method in AudioRecord still does not take into account the hardware latency (they have a TODO comment for that), but the latency() method in AudioTrack do...
In Android, I have a Path object which I happen to know defines a closed path, and I need to figure out if a given point is contained within the path. What I was hoping for was something along the lines of
path.contains(int x, int y)
but that doesn't seem to exist.
The specific reason I'm looking for this is because I have a collecti...

I'd like to serialize a Bundle object, but can't seem to find a simple way of doing it. Using Parcel doesn't seem like an option, since I want to store the serialized data to file.
Any ideas on ways to do this?

So far, assuming i'm equally dumb in both technologies and have to learn them from the ground, i came to ...
