Use plug-in CallAudioControl to switch speaker during call.
Meet two issues:
A. Crash for E32USER-CBASE 46 if deleting CCallAudioControl object when view deactivates. But put CCallAudioControl object in appui and delete it when exiting; the crash doesn't happen.
B. No show battery charging animation after switch speaker
1. Run my app, create CCallAudioControl object
2. Place a voice call in native standby view
3. Bring my app foreground after call connects
4. Switch speaker with API from CCallAudioControl
5. Charge the battery
From my app, fail to show battery charging animation.
if putting my app to background, can see the battery charging animation.
In known issues for CCallAudioControl http://wiki.forum.nokia.com/index.ph...llAudioControl
There is "4) Calling SetOutput(ELoudspeaker) breaks operation of CPeriodic objects with Idle priority "
Does this issue affect battery charging animation when my app is foreground?
