How do I retrieve the data from AsyncTasks doInBackground()?

Question

I\'ll keep this one as simple as I can.

I have a method in my control layer that uses a class CallServiceTask that extends AsyncTask. When

Answer 1

as @saad-farooq mentioned you can use interface for that. So you can use the Handler.Callback or define your own:

public interface ClientIF {

    public void onResponseReceived(Object result);

}

then you need to implement it in your CallServiceTask

public abstract class CallServiceTask extends AsyncTask 
    implements ClientIF
{
    Activity activity;

    CallServiceTask(Activity activity) {
        this.activity = activity;
    }

    public abstract void onResponseReceived(Object result); 

    protected Object[] doInBackground(Object... params) 
    {
        HttpUriRequest req = (HttpUriRequest) params[0];
        String url = (String) params[1];
        return executeRequest(req, url);
    }

    protected onPostExecute(Object result) {
        onResponseReceived(result);
    }
}

note that the costructor is changed so you can call from every Activity class. Then make the instance of this class in your RestClient

public class RestClient
{
CallServiceTask service = new CallServiceTask() {
    @Override
    public void onResponseReceived(Object result) {
    // TODO Auto-generated method stub

    }
};

}
