android - Update issue of an app widget using collection -
i have created app widget using collection app, widget shows date , list of item on particular date. works fine , widget updating required, happen while changing date in widget clicking next , previous button, list not refresh means items not updated on particular date. behaviour random , occur only. why happen, wrong in code.
code have use is:
widgetprovider.class
