Bitcoin - Android app- quick questions

[btcusr]

Hi guys, two quick question with bitcoin android app.

How many keys would this app initially generate ? It shows only one address in the beginning.

When I do 'clear data' through 'application manager',would it delete all the keys and generate new set of keys?

thanks.
