java.lang.IllegalArgumentException: The observer is null

Question

A user of one of my apps reported this error. I\'m confused as to what it means an how to fix it. After a bit of googling...still no luck. Anyone seen this before or know how

Answer 1

An alternative solution is to wrap the ListView and catch the exception. This solution worked for me, and I have yet not found any side effects.

    public class CustumListView extends ListView {


  public CustumListView(Context context, AttributeSet attrs) {
    super(context, attrs);
  }

  @Override
  protected void onDetachedFromWindow() {
    try {
      super.onDetachedFromWindow();
    } catch(IllegalArgumentException iae) {

    }
  }
}
