SipManager cannot create SipService. Cannot Bind Context.SIP_SERVICE in Nougat

问题

I have an application that uses SipManager to open a SIP profile. I have no difficulties opening the SIP profile on my older(KitKat) device, but my new(Nougat) device throws the a SipException "SipService is dead and is restarting..."

Stepping through the SipManager reveals that 'createSipService' is not binding 'Context.SIP_SERVICE'.

I found this post, which seems to be the same issue.

Does anyone know what changed between KitKat and Nougat that would cause such an error, and what I can do to resolve it?

UPDATE

This is the Exception I get when trying to run mySipManager.open(mSipProfile, pendingIntent, null);

This happens on running .open() and .close().

UPDATE 2

I just bought a Pixel 3 (Android 9) and it does not have the issue. I can't speak for 5,6, or 8, but this maybe a bug with 7, as both 4 and 9 do not have the issue.

回答1:

Is Wifi Calling enabled (or can be enabled) on your device?

I have the same issue with an Asus (model X00PD), android is 8.0.

SipManager.IsApiSupported() and SipManager.IsVoipSupported() both return true, however, if I view services under Developer options, Wifi Calling is not running, and the Asus ui disables the option to enable it.

To contrast the Wifi-Calling service is running on my S8 (also 8.0), by default. Same with an older S6(7.0) and a Nokia 6.1(8.1).
