Good day friends!
There is a Service , it starts at boot (well, it seems to be started), creates a task at startup (in fact, several, but they have the same essence). The task does something and falls asleep this way for a while:
TimeUnit.SECONDS.sleep(180); It seems like everything would be fine, but, for example, for the first time after the launch, the task worked for the first time in almost an hour! Well, it's like that? I did before this through a timer, like this:
TT = new myTimerTask(); T2 = new Timer(); if (TT != null && T2 != null) T2.scheduleAtFixedRate(TT, 1000, 1000*60); //-- раз в минуту It worked the same way as it got: then 20 times per second, then after 10 minutes. Here I redid it into tasks - a similar garbage. That interval is observed, then how horrible. What could be the reasons?
The Service itself during hibernation of the phone hangs like Foreground , and when the body wakes up, it leaves the Foreground (the customer’s constantly hanging application icon annoys the customer because of the Foreground , and I Foreground perverted).
Now I look at the logs - the task worked only when creating the Service , 25 minutes passed - there were no more launches (after 5 minutes they should be). Entries in the log of the achievement of onDestroy() Service 'but not. Or is he just silently nailed OS?
Start Service every time you turn off the screen or what?
====== Addition, (almost) the entire Service code =============

Service twitches every time the screen is turned off and on. Those. regularly has the ability to restart, but the logs have no traces of restarting, i.e. he means alive and well. But the task start logs - that is, no. And it happens that there are lighting change logs, but there is no task launch that should occur at the same time ... I don’t misunderstand something.
