ArrayIndexOutOfBounds Exception

[Harshkanani]

My Code : ArrayList<NavigationTabBar.Model> models = new ArrayList<>(); final String[] colors = mFloatingView.getResources().getStringArray(R.array.vertical_ntb);

    models.add(new NavigationTabBar.Model.Builder(AppCompatResources.getDrawable(mFloatingView.getContext(), R.drawable.vector_player), Color.parseColor(colors[0])).title("Player").build());
    models.add(new NavigationTabBar.Model.Builder(AppCompatResources.getDrawable(mFloatingView.getContext(), R.drawable.vector_item), Color.parseColor(colors[1])).title("Items").build());
    models.add(new NavigationTabBar.Model.Builder(AppCompatResources.getDrawable(mFloatingView.getContext(), R.drawable.vector_vehicle), Color.parseColor(colors[2])).title("Vehicles").build());
    models.add(new NavigationTabBar.Model.Builder(AppCompatResources.getDrawable(mFloatingView.getContext(), R.drawable.vector_injector), Color.parseColor(colors[4])).title("Injector").build());
    models.add(new NavigationTabBar.Model.Builder(AppCompatResources.getDrawable(mFloatingView.getContext(), R.drawable.vector_esp_settings), Color.parseColor(colors[3])).title("Aimbot").build());
    if(!models.isEmpty())
            header_tabbar.setModels(models);

    viewpager.setPageTransformer(false, new CubeInTransformer());
    viewpager.setAdapter(new MyPagerAdapter(getApplicationContext()));
    viewpager.setOffscreenPageLimit(5);
    header_tabbar.setViewPager(viewpager, 0);
