Android Oreo (8.0) support about re HOT 9 CLOSED

not easy to fix, because there seems no native way to get the dns server without java JNI.
see: c-ares/c-ares#148

from re.

I did some research and found this answer on SO https://stackoverflow.com/a/48973823

I've managed to get a native implementation to work by implementing the method that executes the getprop command.

hi @Hmart would you like to help to fix this issue? if you have some working code
perhaps you can submit a Pull Request ?

A workaround may be to statically configure a public DNS server (e.g. 8.8.8.8)
in the application.

@Hmart, did your getprop method call a java function via JNI? Could you share your implementation?

from re.

Alfred, are you suggesting that in case of libbaresip.a, src/net.c, dns_srv_get() calls would be modified to use 8.8.8.8?

from re.

Is get_android_dns function really needed in library? As I can see in the code it is used only in dns_srv_get which is unused in library too. May be it is better to make external applications find this information themselves?

from re.

hi @juha-h

baresip can use the config option dns_server to add any custom nameservers.
I dont think we should hardcode any IP-address in the source code.

comment to @AlexanderplUs :

the function dns_srv_get is unused in libre. The intention is that the application
can call it to get a list of nameservers from the OS. It is practical to have this function
available, but it is also limited to platforms that provide the needed APIs.

I dont think we will find a good solution for this, so I suggest we close the ticket.

the recommendation will then be for the application to fetch the nameservers.
