I was writing some code based on the DialerAppUi.cpp, but my emulator software continued to fall, so I had to investigate and fix the trouble. During the investigation, some questions are hard to understand, need help.
Question 1: I failed to catch the trouble with TRAPD, it always simply fall, what does it mean?
Question 2: What does "has exited with code 199972 (0x30D24)" mean, what type of error is this?
Question 3: When I get the phone line info by the RPhone.GetLineInfo function, it returns -1 in iStatus (what status is this, btw?) and 24051676 in iLineCapsFlags, what flags are these, where's the info on 'em?
Is it possible to test dialer functionality on the emulator?
Thanks for the attention.
