How to Android koush/ion get data?

I am working as an Android developer. I am facing an issue is I can't access the results inside the onCompleted method, I want to get the data from an onCompleted method and send to my view.

 public double walletApiCall(final Activity myactivity, final String addresses) {
    double unCon_balance;
    Ion.with(myactivity)
           .load(URL)
            .asString()
            .setCallback(new FutureCallback<String>() {
                @Override
                public void onCompleted(Exception e, String result) {

                    JSONObject tomJsonObject = null;

                    try {
                        tomJsonObject = new JSONObject(result);
                    } catch (JSONException e1) {
                        e1.printStackTrace();
                    }

                    walletApiCall(result,myactivity);
                    System.out.println("unCon_balance2: "+ unCon_balance);
                }
            });

    return unCon_balance;

}
