How to close Soft Keyboard?

Hi

I'm developing an app on an Android phone phone which requires the soft keyboard. This works fine however closing the keyboard on pressing the enter key is proving to be problematic.

I'm using

PHP Code:

---

stage.focus = null 


---

to take the focus away from the text field which should work, however this crashes my app with the following error:

The application App (process air.myappname) has stopped unexpectedly. Please try again.

Does anyone have any ideas as to why this would be happening?

Thanks.

I found what was causing this issue so if anyone else experiences a similar issue try looking at 3rd party apps installed on your phone. In my case it was a soft keyboard app called Swiftkey that was creating the error and crashing my phone. I disabled this and everything works fine now.
