Thank you, Mark. I read your linked topic, But AlarmManager is not suitable to me.
My service is not started periodically, it started by broadcast, Actually by "android.intent.action.PHONE_STATE". On each starting, the service should load a big database, this spend about serveral seconds, so I don't want to load it each time "android.intent.action.PHONE_STATE" arrive, I leave the service runing. For each "android.intent.action.PHONE_STATE", a UI should be present to user while calling, in order to show the UI in front of calling and not to interrupt the interaction with phone call, the UI should not be a activity, I user "WindowManager.LayoutParams.TYPE_SYSTEM_ALERT" with FLAG__NOT_FOCUSABLE. In above condition, except to Service, there is any better class I can use? pls advise me. If I have to user Service, Where should I do cleaning up and saving settings? Thank you!
