Question

I’ m designing Android client for a web site. So there are a lot of different network operations i have to implement. For a example user authorization or searching on a server. To do this I must send JSON request to REST web server with some parameters and URL. So I must pass not only String parameters but some data structure (LinkedHashMap for instance). The problem i don’t know the most correct way. By far I did next:

1. protected Boolean doInBackground(Object... param). And then convert param[0],param [1] to different type. I think it is a bad way.
2. Using javatuples library for this purpose:

protected Void doInBackground(Pair<String, LinkedHashMap<String, Object>>... params)

It seems too complex and redundant code. And the most important I must add

@SuppressWarnings("unchecked")

or I got a type safety warning.

So may be some experts can help me with this and advice the most correct and efficient way.

Answer 1

You could have your own constructor for the Asynctask and store these as fields which you could use in doinBackground

    private class Task extends AsyncTask<Void, Void, Void> {

    Task(int a, long b){
       //store a, b
    }
    @Override
    protected Void doInBackground(Void... arg) {    
    }   
  }

and then

new Task(1,2).execute();
