You can synchronize the ICSx⁵ account like every other system account over the Android API. No special actions are needed for ICSx⁵. I think automation apps should support that.
Excellent. Thank you!
Setting sync to 10 or 5 doesn’t stick. 15 and greater works fine. Experimentation indicates that the sync interval of 5 or 10 is not silently respected in the refresh rate.
Indeed. Android doesn’t allow that for battery saving reasons.
We had to remove 5 and 10 minutes as options because in recent Android versions 15 minutes is the fastest sync interval which is allowed by the system.
