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'.
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!";
}
}
}

57,712 PointsHi 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.
