 Hi,

 I am new to Android and I am looking at the Notepad Tutorial sample code 
 now. In the NotesDbAdapter class, it defines a close() method to close the  
 DatabaseHelper. However I cannot find this method get called anywhere. 

 So my question is when shall we close the DB connection. I suppose we 
 should call it in the onDestroy() mehod of each Activity class. Or will 
 Android framework will take care of this so we don't have to worry about 
 it? 

 Please advise. thanks.

But what if you need to close the connection and you don't want to put it 
in the onDestroy, coz the onDestroy gets called when you change the 
orientation.

We don't need to keep closing and opening the connection when ever the 
activity gets recreated. Also we need it such a way that the activity needs 
to destroyed on origination change.



What are my options ?

 Hi Jay,
 no you just have to call the closing mechanism once. Normally during
 the onDestroy() event of last Activity that remains on the system.
 This is normally the launcher Activity.

 @Override
protected void onDestroy() {
Log.d(TAG, onDestroy fired!);
dbhelper.close();
super.onDestroy();
}
