Hi,

I am sorry that such a problem occurred while testing the project. I did not encounter this before and thus I searched by your text Unfortunately (OO) has stopped but all search results are about System UI has stopped Working. I do not clearly know whether the problem is an exception in my code, FYI it is pre-tested and works properly, or it is a problem in the Android device.

Could you please give more information on a screenshot of what happens?

Hi, may I know where should I run this code? Android studio?
