 You can tack on another "me too" to the never-ending list of useless "still
nothing here" posts on the other Device Seeding Program thread. But please,
not another fruitless "where's my phone" thread. Please?

1. Checking to See if I directory Exsits

I have a string called extStorageDirectory which is set to my SD Card
and then "/mypics",  I can then save a picture in to this directory,
but only if the directory exsists.

So how do I check to see if the directory exsits, and if it doesn't
creates the directory?

Thanks in advance ;-)


2. Keeping some data in memory during onDestroy->onCreate

I want to monitor the velocity of a phone. I can do this by looking at
accelerometer data over the last 30 seconds, saving about one sample
every 0.1 seconds (300 samples) and applying a sliding filter to the
data. If I create a service to do this, what's the best way to
preserve the state of the filter (600 doubles) between an onDestroy
and a subsequent onCreate? I can set up an SQLite table to hold the
values but that's a lot of extra coding and processing overhead. Is
there a better way?
