Hi All, Just a "simple" question, how do you guys handle re-registration, invites and keep-alives in android when the phone is in deep sleep mode? I've tried many techniques but I'm still not getting a reliable way to keep the phone registered. My current app uses a native library to simplify the pjsip API access from java and all the pjsip callbacks I need are just calling back some java methods to get notified the app regarding some events. Everything works just fine if I keep the phone connected to USB. As soon as I unconnected it from USB the app keep connected and reachable up to the next re-registration which doesn't complete because the phone entered in deep sleep mode. I've also tried to grab the partial wakeup lock from a JNI callback in order to wakeup the phone at each invite and re-registration events, but seems not really working, the phone still enter in deep sleep mode and never re-register. A semi-reliable way I've found is to set a repetitive timer to wakeup the phone, just for few seconds, to complete the re-registration process. But this has the drawback of battery drain problem. Does anyone has a better approach to get reliable re-registrations and reachability on android application when the phone is in deep sleep mode? I really like to know if someone has sorted out this problem. Thanks in advance, Roberto Fichera.
