How to make AsyncTask modular in android

Question

I am quite new to Android Development. I am working in a app where i need to make a lot of async calls to api. For each and every API call, I have to write the similar looking AsyncTask class over and over again. So, is there any way to make these Async Calls modular?

Answer 1

yes it is possible use Listener and AsyncTask with parameterized constructor

Check it

Create an interface

public interface OnTaskCompletListerner {
 void oncompleteListerner(String name);
}

create an AsyncTask class as follows

public class AsyncTaskModuler  extends AsyncTask<Void, Void, String> {

    private Context context;
    private HashMap<String, String> data;
    private String URL;
    private OnTaskCompletListerner taskdone;

    public AsyncTaskModuler(Context ctx,HashMap<String, String> data,String url,OnTaskCompletListerner taskdone){

        this.context=ctx;
        this.data=data;
        this.URL=url;
        this.taskdone=taskdone;
    }

    @Override
    protected String doInBackground(Void... params) {
        //Do the task here and return the value if needed 
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        taskdone.oncompleteListerner(result);
    }

and call it in your activity like this

public class CallAync extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String url="";
        HashMap<String, String> data=new HashMap<String, String>();
        AsyncTaskModuler moduler=new AsyncTaskModuler(CallAync.this, data, url, completListerner);
        moduler.execute();
    }

    OnTaskCompletListerner completListerner=new OnTaskCompletListerner() {

        @Override
        public void oncompleteListerner(String name) {

        }
    };
}
