Multiple handler loop Android

I am trying to design a program that makes multiple API calls on a website (Each "name" has several modes that I have to loop through before I move on to the next name). The problem is, you are limited to calling the API once every second. I thought the handler was the way to go but now I don't think so.

It runs through the loop just fine but I don't think so. I get the following error:

EDIT: Figured out that this was being caused by

When I make this call in my Asynchronous task:

String[] metrics = r.getStringArray(R.array.metric_apicall);

I don't think my code is designed right for what I am trying to do. Can anyone tell me if this is the right approach?...Also, APICallData(MainActivity.this, app, mode).execute(); is an asynchronous task.

//Other code above this irrelevant

    mApp = 0;
    mMode = 0;
    callAPI(mMode, names[mApp]);
    mMode++;

    while (mApp < names.length) {
        while (mMode < metrics.length) {
            Handler handler = new Handler(); 
            handler.postDelayed(new Runnable() { 
                public void run() { 
                    callAPI(mMode, names[mApp]);

                }
            }, 1010); 
            mMode++;
        }
        mMode = 0;
        mApp++;
    }

private void callAPI(int mode, String app) {
    new APICallData(MainActivity.this, app, mode).execute();
}

I think you should use Timer and TimerTask and exeute it with an interval of 1 sec.
