Question

basic question – I’m still learning Android – trying to create a seperate thread to do a DB query and having a problem. I’ve put my DB routines in their own class but can’t seem to access it from the thread:

public class TripsScreenActivity extends Activity implements OnClickListener {

public class dbThread extends AsyncTask<Cursor, Integer, Cursor> {

    @Override
    protected Cursor doInBackground(Cursor... arg0) {
        // TODO Auto-generated method stub

        // Link to WYWHApplication module
        WYWHApplication wywh = (WYWHApplication) this.getApplication();

        try {
            Cursor tripList = wywh.getBasicList();

…but Eclipse is giving me the following error:

The method getApplication() is undefined for the type TripsScreenActivity.dbThread

Sorry, probably an obvious answer…any help gratefully accepted.

Answer 1

this refers to the AsyncTask when used inside doInBackground().You want to refer to your activity, so use TripsScreenActivity.this.getApplication()¹ instead of this.getApplication().

¹ that’s called a “qualified this”
