Passing ArrayList<NameValuePair> to ASyncTask and Update Values

Issue

I am working on a project where I am trying to implement an ASyncTask to post to a web server.

I have my class defined as follows:

public class PostToAPI extends AsyncTask<List<NameValuePair>, Void, JSONObject> implements DialogInterface.OnCancelListener

I have my doInBackground method defined as follows:

protected JSONObject doInBackground(List<NameValuePair>... postData)

I am trying to create a new ArrayList<NameValuePair> which will include everything in postData plus some extra values but I keep getting an error.

Below is what I've tried

protected JSONObject doInBackground(List<NameValuePair>... postData)
{
   List<NameValuePair> updatedPostData = new ArrayList<>();
   updatedPostData.addAll(postData);
updatedPostData.add(new BasicNameValuePair(Defines.PreferenceSettings.ACCESS_TOKEN,
                        settings.getString(Defines.PreferenceSettings.ACCESS_TOKEN, "")));
                updatedPostData.add(new BasicNameValuePair(Defines.PreferenceSettings.USER_ID,
                        String.valueOf(settings.getInt(Defines.PreferenceSettings.USER_ID, 0))));
}

I'm getting an error on the updatedPostData.addAll(postData). The error is:

addAll (java.util.Collection? extends org.apache.http.NameValuePair>) in
List cannot be applied to (java.util.List<org.apache.http.NameValuePair>[])

Now that looks to me like doInBackground is passing an array of List which I don't want.

Solution

Since there is only one element in postData, just add a subscript like this:

updatedPostData.addAll(postData[0]);
