CSipSimple - Getting started to hack it (tailor to my needs)
Dennis GuseJust one or two things I need to remember about CSipSimple:
Infrastructure:
- SipStack runs in background (communication via Parcable interface). It interacts with PJSIP. Important there is a watchdog timer (about 5s)!
- pjsua.java, pjsuaConstants is the SWIG generated interface to PJSIP
- Native functions never return boolean, check for pjSuaConstants.PJ_SUCCESS
- Be aware of string exchange with the native stack: PjSipService.pjStrToString(…)
- UAStateReceiver.java does the call creation and everything related to SipStack
- PjSipService.java is deeply integrated with UAStateReceiver.java (for example does recording…)
UI:
- CustomDistribution.java defines some things for fast modifying the behavior
- Main screen is created in SipHome.java (incl. the slidable tabs) To remove tabs, just disable tab.add (except for the warning tab and the message tab [message disable in CustomDistribution.java]: may be triggered from outside)
- Notifications are handled in SipNotifications.java (but from Sip-Thread)
- DialerFragment.java is the dialer incl. call button and account switcher… Here the re-dial functionality is missing… (press the call button twice without number should redial previous number)
- InCallActivity.java :) Important call setup is done BEFORE launching the InCallActivity via SipManager.ACTION_SIP_CALL_UI from UAStateReceiver.launchCallHandler(…). There is even a activity start delay of 2000ms (UAStateReceiver.LAUNCH_TRIGGER_DELAY). I think it’s not nice!!!! Because a user may hear sound of before the UI is ready, but there is might be a problem with race conditions…
- InCallControls.java is the ui element on the bottom of InCallActivity to control Bluetooth and loudspeaker etc. (Deeply integrated with InCallActivity: sadly NO MVC…)
- InCall.java is also related to Dialer
