How To Properly Update A Widget In Android 8.0 - Oreo - API 26

由 跟風遠走 提交于 2019-11-27 00:53:31
问题 Let's say I have a widget for an app that has targetSDKVersion set to 26. This widget takes between 100ms and 10s to update. Most of the time under 1s. Before Android O, if onUpdate() was called on my AppWidgetProvider, I could launch a background service to update this widget. However, Android O returns an IllegalStateException if you attempt that behavior. The obvious solution of starting a foreground service seems like an extreme measure for something that will be done in under 10s 99% of

由 我只是一个虾纸丫 提交于 2019-11-26 22:46:30
问题 I'm targeting sdk version 27 with a minimum version of 19 and trying to get a service that runs continuously in the background. I tried different service start options but it still got killed with the app. I tried using a BroadcastReceiver to start the service when it got killed but that gave me an error saying that the app was in the background and couldn't start a service so I tried using the JobScheduler and that gave me the same error. How is this supposed to be done? For example, if I
