问题 I am working with Android Support package. I have created a dialog: Dialog dialog = new Dialog(activity, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); Since I would like the dialog show in a full screen, so I applied the theme Theme_Translucent_NoTitleBar_Fullscreen to it & it works. I have following two questions: I would like my dialog to show like full screen still but leave the top ActionBar not be covered by it, what Theme should I use then? How to have an gray color overlay

问题 Android 8 has its background execution limits, so when we started targeting Oreo we changed our services to using JobIntentSerivce to be able to get work done. However, we have a widget that updates every few minutes with live score data. The widget's service extends the good old RemoteViewsService.

问题 As far as I understood the official documentation about Widgets I am a little bit confused. The "standard" way would be to define a BroadcastReceiver and define the update frequency in milliseconds - this way allows a minimum update interval of 30 minutes to save battery power. Sounds reasonable. The "manual" way I found reading the Google documentation would be to handle the update of widgets yourself using the AlarmManager . Using this method higher update intervals are possible (though of
