android View not attached to window manager

Question

I am having some of the following exceptions:

java.lang.IllegalArgumentException: View not attached to window manager
at android.view.WindowManagerImpl.findV         


        

Answer 1

If you have an Activity object hanging around, you can use the isDestroyed() method:

Activity activity;

// ...

if (!activity.isDestroyed()) {
    // ...
}

This is nice if you have a non-anonymous AsyncTask subclass that you use in various places.
