telerik / android-samples Goto Github PK

The example codes in this repository works fine on normal internet speed but application crashes on slow internet or while trying to call downloadUrl() when the google sheet is still updating. Any help?
It is advised to check if the final JSONObject is null or not?
Thanks.

when i am using RadCartenChartView, i got nullpointer error.

code:

  RadCartesianChartView chartView = new RadCartesianChartView(MainActivity.this);


    BarSeries barSeries = new BarSeries(this);
    barSeries.setCategoryBinding(new DataPointBinding() {
        @Override
        public Object getValue(Object o) {
            return ((MonthResult) o).getMonth();
        }
    });
    barSeries.setValueBinding(new DataPointBinding() {
        @Override
        public Object getValue(Object o) {
            return ((MonthResult) o).getResult();
        }
    });
    barSeries.setData(this.monthResults);
    chartView.getSeries().add(barSeries); --> nullpointer excpetion here..
