Android M has a new feature called App Standby where an app is put into an idle state when it's not being utilized (see docs) and, among other things, its network access is disabled.
I can't seem to figure out a way to determine when the app goes into and out of this state (via a broadcast intent or something of the like) and I really need to as my app relies on having network periodically to check the status of a server.
Can someone help me figure out how to determine when my app goes into and out of idle state?
I've been digging through the M preview 2 source and down through the calls of $ adb shell am set-inactive it appears that there's a AppIdleStateChangeListener but it appears to only be used internally to Android and isn't exposed to us lowly developers who want to know when our apps can use the internet :-(
So far, it appears that when ACTION_POWER_CONNECTED is broadcast, all apps come out of standby...this is a potential workaround if Google doesn't expose something for us before release.
