Timer mechanism not suitable for Android #78

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The NIST SIP stack part makes use of Java Timer and its schedule method. 
Unfortunately, timers in Android may not be executed on time if device is 
sleeping.
I think we do have three options:
a) change from Timer to AlarmManager which would result in a massiv 
reconstruction
b) set wakelocks for the time any recuring timer is active which may drain the 
battery
c) mitigate the impact for a recurring timer by checking with every tick 
whether the overarching timer is still valid or already exceeded. In the later 
case: fire the timeout event "immediately" and forget about the remaining ticks.
