Handle CursorLoader exceptions

Question

I have a Fragment implementing LoaderManager and using CursorLoader (nothing fancy). I want to catch exceptions thrown during the query but I don't see how!!! Any help? Thx.

You would need to derive from CursorLoader to do it. Something like this:

class MyCursorLoader extends CursorLoader {

    public MyCursorLoader(Context context) {
         super(context)
      }

    public CursorLoader(Context context, Uri uri, String[] projection, String selection,
            String[] selectionArgs, String sortOrder) {
        super(context, uri, projection, selection, selectionArgs, sortOrder);
    }

    @Override
    public Cursor loadInBackground() {

        try {
            return (super.loadInBackground);
        } catch (YourException e) {
            // Do your thing.
        }

        return (null);
    }

}

You can adapt it to implement your error handling.
