change widget update interval programatically android

Question

I am working on Android widgets in my app. I have a Settings screen from where user can select content of widget and update interval of widget. There is AppWidgetProviderInfo API but don't know how to use it or is there any other way to change widget update interval? Please help me.

Thanks in advance.

Answer 1

is there any other way to change widget update interval?

Rather than using android:updatePeriodMillis , you will need to use AlarmManager to arrange to get control and update your app widget. You cannot modify android:updatePeriodMillis at runtime.

Answer 2

Add the following code in your AppWidgetProvider class in the onUpdate void.

int updateTime = 1800000; //30 min
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                               System.currentTimeMillis(),
                                updateTime,
                                pendingIntentAlarm);
