Question

When I run the below code, everything goes great until I change the value of the seekBar. The onProgressChange changes the value of the text for myValue. I get a force close and it gives me the log cat entries below.

While going through debug, the exception thrown said it could not find ID 2, which you can tell is myValue, to be expected. Please let me know what you think.
Thanks

You are setting the text to an int, so Android thinks you are trying to reference a resource by id. Converting progress to a string should solve your problem. E.g. Integer.toString(progress).
