RequestResponseHandler

public interface RequestResponseHandler {
    void response(String result);
}

Calling HttpGetRequestTask

new HttpGetRequestTask(new RequestResponseHandler() {
    @Override
    public void response(String result) {
        try {
            JSONArray reader = new JSONArray(result);
            for (int i = 0; i < reader.length(); i++) {
                JSONObject jsonObject = reader.getJSONObject(i);
                int id = jsonObject.getInt("id");
                String name = jsonObject.getString("name");
                String packageName = jsonObject.getString("package");
                MenuItem menuItem = myAppsMenu.add(100, id, i, name);
                
                View actionView = new View(getApplicationContext());
                actionView.setTag(packageName);
                menuItem.setActionView(actionView);
            }
            
        } catch (JSONException e) {
            e.printStackTrace();
        }
        
    }
    }).execute("http://boyuzatma.evhediyesial.com/api/v1/advertisements/" + getPackageName());
