I was working with background threads and orientation changes. i have gone through the code given here.
https://stackoverflow.com/q/1512263 and some other posts too.

i’m using “android:configChanges=”keyboardHidden|orientation” for handling screen orientation changes. it works fine but when i want to finish this activity it gets forced close with a runtime exception with a message “Unable to destroy activity..”
any idea to finish my activity safely?

Log output is:

    You shouldn’t really use the technique you’re using. I’ve written two blogposts about this:

    Actvity and background threads (part 1)
    Actvity and background threads (part 2)

    But since fragments were introduced, there is much easier way of handling background threads now: so called retained fragments (see an example here).
