Mashup issue

Hi all,

I created a mashup and intergated with the mobile app. Then.my requirement is :when I choose a field value,then will trigger the other

event. Iit's OK on PC and iphone,but it 's not OK in Android system.

In Android system, when I choose a field value, I had to touch someplace where it is not QS object(eg.HTML P TAG), thus it will trigger

the event. I use the codes to Detect Html page  as bellows:

Something wrong or any ider?

Thanks.
