What does "invalid statement in fillWindow()" in Android cursor mean?

Question

I sometimes see this error in my logcat output,

Cursor: invalid statement in fillWindow(). 

It sometimes happens when I press the back key and then it goes to the default Android listview before going to my custom listview.

What does it mean? How do I solve it? Because it does not point to any line of code where the problem is coming from.

When dealing with ListActivities, this issue has to do with the Cursor objects, CursorAdapter objects, and Database objects not being closed properly when the Activity stops, and not being set properly when the Activity starts or resumes.

I had to make sure that I closed my SimpleListAdapter, my Cursors, and then my Database objects in that respective order, in the onStop method of the Activity that is called when the TabActivity resumes.

I had already been closing the Cursor and Database objects, but had not been closing my SimpleListAdapter Cursor.

/**    * onStop method    *     * Perform actions when the Activity is hidden from view    *     * @return void    *     */   @Override   protected void onStop() {     try {       super.onStop();        if (this.mySimpleListAdapterObj !=null){         this.mySimpleListAdapterObj.getCursor().close();         this.mySimpleListAdapterObj= null;       }        if (this.mActivityListCursorObj != null) {         this.mActivityListCursorObj.close();       }        if (this.myDatabaseClassObj != null) {         this.myDatabaseClassObj.close();       }     } catch (Exception error) {       /** Error Handler Code **/     }// end try/catch (Exception error)   }// end onStop
