<p>I have old (pre-random-number-bug) addresses in my android bitcoin wallet app, with 0 balance. After patch I am using a new address (with balance) and still keeping my old address in my wallet. Should I delete my old addresses from my android app?</p>

<p>Let's say some one cracked my old key, and imported it into his wallet. In this case, is it anyway possible for him to do a sweep transaction? I remember, something like this happened with blockchain.info / mywallet app but I am not very sure.</p>
