Android Question When touch the EditText, the program jumped out (crash)

[foretek]

I use an EditText in my APP. First a string is loaded to the EditText.Text, and when the EditText is touched on screen, it pop up a keyboard and works. In the APP, another string is then loaded to the EditText.Text, this time when the EditText is touched, the program is crash. I couldn't catch the cause of the problem. I got some message as below. Can anyone give me a hint what the problem might be? Thanks.
