VerifyError in App After Upgrade
<p>I've got a small issue which I was hoping someone could give me some insight on.</p>

<p>Sometimes, when a user updates my app from the market (from one version to another) they get a VerifyError upon running the app.  It happens to a random class; you can use part of the app, then going to a different Activity in the app causes it to blow up.  This only happens once; once Dalvik gets it out of its system it never happens again.</p>

<p>Since it only happens once per update (and most of the time, not at all), it is admittedly a minor issue, but I think it reflects badly on my app, so if anyone has any ideas that would be great.</p>

<p>The stack traces don't seem that helpful, since they always happen in a different place (which further confuses me).  Here's an example of one:</p>
