ArrayAdapter and ListView - ArrayIndexOutOfBoundsException

I'm really hoping someone can help me out with this one. I've been stuck on it forever. Occasionally, when someone is using my app, it'll force close with this exception:

java.lang.ArrayIndexOutOfBoundsException

    at dalvik.system.NativeStart.main(Native Method)

However, I cannot figure out why. It's relatively rare, non-reproducable, and the stacktrace is completely unhelpful because it doesn't include any of my code.

Is it a bug in Android itself?

In addition to what Romain said, it seems to be important that the largest view type is smaller than the view type count.

I had two view types defined (for what ever reason) with 1 and 2 and returned 2 in getViewTypeCount() which gave me the same exception as above. Re-indexing the types to 0 and 1 fixed the issue.

What version of Android are you running? From what I can tell your Adapter is returning the wrong count from getViewTypeCount() (or you are changing the view type count dynamically which is a big mistake.)
