Calling Web Service Using Async Task In Android?

I have my separate web service class in which i just pass response method, url and array list of data which is required for making the request and getting the response. I call this

Solution 1:

You can try below code for Async Task and also call web service in doInBackground:

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;

publicclassAsyncExampleextendsActivity{


privateString url="http://www.google.co.in";

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
     newAsyncCaller().execute();
}


privateclassAsyncCallerextendsAsyncTask<Void, Void, Void>
{
    ProgressDialog pdLoading = newProgressDialog(AsyncExample.this);

    @OverrideprotectedvoidonPreExecute() {
        super.onPreExecute();

        //this method will be running on UI thread
        pdLoading.setMessage("Loading...");
        pdLoading.show();
    }
    @OverrideprotectedVoiddoInBackground(Void... params) {

        //this method will be running on a background thread so don't update UI from here//do your long-running http tasks here, you don't want to pass argument and u can access the parent class' variable url over herereturnnull;
    }

    @OverrideprotectedvoidonPostExecute(Void result) {
        super.onPostExecute(result);

        //this method will be running on UI thread

        pdLoading.dismiss();
    }

    }
}

Done
