Finally, save this ParseObject in the background and pass in the mSaveCallback member variable.

import android.app.Activity;
import android.widget.EditText;
import android.widget.Toast;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.SaveCallback;

public class MainActivity extends Activity {

    protected EditText mDescriptionField;

    protected SaveCallback mSaveCallback = new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Toast.makeText(MainActivity.this, "Item saved!", Toast.LENGTH_SHORT).show();
        }
    };

    // Some code omitted!

    public void save() {
      ParseObject mTask .new ParseObject("Task");
      // parseObject.saveInBackground(mSaveCallbck); // duplicate code? 
      String description = mDescriptionField.getText().toString();
      mTask.put("description", description);
      mTask.saveInBackground(mSaveCallbck);  // this is correct but the callback is called mSaveCallback


    }
}
