Hi, everyone, I have a forecast widget that can show the now time and the latest weather forecast. But I want to make the now time have a on-click event and then turn to Clock page (it provide by system and in setting page). How can I click the widget button, than it can change page to "Clock" or "Calendar". Besides that, the now time function is using "AlarmManager" to count down the update time at each minute. How can I make it more save powe? ( such as start count down when screen-on <--how to make it?) many thanks.
