Can't create database manager under Fragment Activity class

Question

I am now trying to create new database manager under Fragment class. But unfortunately, I just stuck in the middle of some strage error that i never face with it before. Please have a look at below codes.

public class About extends Fragment {
DBManager gDatabase = new DBManager(this);
private AboutInfo ai;

The error code is that The constructor DBManage(About) is undefined. Two quick fix available:

Change constructor 'DBManager(Context) to 'DBManager(About)'' Create constructor 'DBManager(About)'

And here is my database manager codes.

public DBManager(Context context) {
    super(context, DB_NAME, null, 1);
    DBManager.myContext = context;
}

What is wrong with my codes? Any quick help would be appreciate.

It needs an Activity context, not a Fragment context.

Try:

DBManager gDatabase = new DBManager(getActivity());

I would suggest passing the `getApplicationContext()` just to ensure that no memory leaks occur :) – Alex Lockwood Jun 24 '12 at 15:36
