call a method several times before getting response from volley

I am getting base 64 encoded format image string from server: hNiCHLy9Ax3gKMv81IBJ1457175735.So I downloaded and use that imagestring to covert that into bitmap.

Now My only problem is, I have to call the loadImage(base64Image) method nearly eight times inside that for loop.But it is not calling the method single time because of asynchronous volley, it directly get into volley get response.

Because of that I can't save values to arraylist.that's why I am getting arrayIndexOutOfBoundException.

Below I have posted the logcat and codes relevant to this issue:

        return temp;
    }

I need to call volley GET response after called loadImage(base64Image) method eight times.any suggestion

So basically u want to avoid all the work you are doing in onResponse till the load image is called the number of times equal to the size of alAvaArr array. So, you can declare a global int variable up and increment it each time in onResponse. Now check in on response that the value of this variable is equal to the size of alAvaArr array or not. If not, do nothing else whatever you wana do in OnResponse:

                    dialog.dismiss();

                    try {

                        Toast.makeText(getActivity(), "Running ", Toast.LENGTH_SHORT).show();

                        getSwipeImage();

                        myAppAdapter.notifyDataSetChanged();

                    } catch (Exception e) {
                        e.printStackTrace();
                        dialog.dismiss();
                    }
