IndexOutOfBounds on Spinner?

I have a problem with interpretation of stack trace.. The peoblem is that there is no class from my package and so it is hard for me to find out what is happening.. As I fallowed trace, I think it's about an adapter and spinner, but on that page I have 6 spinners, I debug them all and didn't find anything weird (like selectedItemPosition or something)..

Maybe someone had similar problem? Here's th trace. If you need some code, tell me

I don't know what to do..

See if you have setSelection() called on any of the spinners that may have index that greater than the spinner's adapter size. e.g. if your spinner has two items, and if you call setSelection(2), this will result in IndexOutOfBoundsException exception.

Furthering @FrancescoR 's comment, this code may help you avoid your code crashing while you try and track down the bad call. I had to make this a reply because adding code in the comments was quite nasty.

private void spinnerSetSelectionChecked(Spinner spin, int index) {
    spinnerSetSelectionChecked(spin, index, true);
}
private void spinnerSetSelectionChecked(Spinner spin, int index, boolean animate) {
    final int count = spin.getAdapter().getCount();
    if( (count > 0) && (index < count) ) {
        spin.setSelection(index, animate);
    }
    else { // do nothing
    }
}

To find what spinner is the one with the problem:

• Make a backup copy of your page
• Delete 5 of the 6 spinners
• Test the page
• Repeat to keep only 1 spinner at the time, until you have done to test each spinner on your page

That's what I'd do. I hope this will be of help.
