Answer 1

if you want change bars color prefer pass context as well like example below

ArrayList<BarEntry> entries = new ArrayList<>();
        entries.add(new BarEntry(87f, 0));
        entries.add(new BarEntry(90f, 1));


        ArrayList<String> labels = new ArrayList<>();
        labels.add("title 1");
        labels.add("title 2);

        BarDataSet dataSet = new BarDataSet(entries, "# of Calls ");
        BarData barData = new BarData(labels, dataSet);
        dataSet.setColors(new int[]{R.color.color1 , R.color.color2} , context);
        barChart.setData(barData);
        barChart.animateY(3000 , Easing.EasingOption.EaseOutBack );

Answer 2

You are passing the resource id to the library, not the actual color.

Use this to get the color:

    int color = ContextCompat.getColor(context, R.color.chart_color);

    LineDataSet dataSet = ...;
    dataSet.setColor(color);

You can also find this in the documentation.
