Build A Blog Reader Android App

Please help I ve been stuck here for a while

Inside 'onPostExecute()', set the member variable 'mStatus' to the value passed into 'onPostExecute()'. Then call the 'updateStatusLabel()' method of 'CustomActivity'.

CustomActivity.java
import android.os.AsyncTask;
import android.os.Bundle;

public class CustomActivity extends Activity {

    public String mStatus;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_custom);
        CustomAsyncTask task = new CustomAsyncTask();
        task.execute();
    }

    protected void updateStatusLabel() {
        super.updateStatusLabel();
    }

    protected class CustomAsyncTask extends AsyncTask<Object, Void, String> {   
        @Override
    protected void onPostExecute(String mStatus) {
    }
        protected String doInBackground(Object... params) {
            // Imagine this is some code to do some work
            return "Done!";
        }
    }
}

Hi there,

First, you need to create the onPostExecute() method. That needs the @Override keyword too.

You've got that method surounding the doInBackground() method; it is separate and should be after that.

The method doesn't return anything but does take a String as a parameter. I called that result.

Inside the function, you can set the value of mStaus to the parameter passed into the method. You then call the updateStatusLabel() method.

That all looks like:

protected class CustomAsyncTask extends AsyncTask<Object, Void, String> {   
    @Override
    protected String doInBackground(Object... params) {
        // Imagine this is some code to do some work
        return "Done!";
    }
    @Override
    protected void onPostExecute(String result){
      mStatus = result;
      updateStatusLabel();
    }
}

I hope that all helps. It's been ages since I did this course so I just went through the challenge and found that this worked for me. I hope that means it's correct!

Steve.
