How to extract return vlaue of AsyncTask?

Issue

I have in my app data retrieval by using http GET method. Once the task finishes, i wish to display the return vlaue in my mainActivity (I have just 1 activity in my app at the moment)

This is my asyncTask class:

class getAsync extends AsyncTask<String,Void,String> {
    String ret;
    @Override
    protected String doInBackground(String... params) {
        String url = params[0];
        myGetReq myget = new myGetReq();
        ret = myget.get(url);
        Log.d("[RETURN STATUS]",ret);
        return ret;
    }
}

and from my main activity, i use it in the following way:

getAsync get = new getAsync();
get.execute(url);
statText.setText(get.ret);

where statText is a text in my activity window. It stays blank, even tough I can see in logcat the body of the response. How to I deliver this data back, properly, to my activity?

Solution

Asynce Task have onPostExecute Method... In this method you can work on UI componetnt so i have settext in onPostExecute ... use below code..

class getAsync extends AsyncTask<String,Void,String> {

    @Override
    protected String doInBackground(String... params) {
        String url = params[0];
        myGetReq myget = new myGetReq();
        String ret = myget.get(url);
        Log.d("[RETURN STATUS]",ret);
        return ret;
    }

   @Override
        protected void onPostExecute(String result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
            statText.setText(result);

     }

}
