Go / etc / resolv.conf is missing in android

Question

I cross-compiled Go source code in Arm to run on Android. The program runs in the terminal on the Android device, but I get an error that /etc/resolv.conf is missing. My program relies heavily on the network / http library for creating http calls.

How can I handle this error in Android?

Answer 1

As right now you cannot use the built-in network / http to connect to host names, check issue .

There are several workarounds that you can use.

• generate / etc / resolv.conf when your program starts, if you have root access, ugly but simple and simple.

• Save the resolv.conf file somewhere and pay http://golang.org/src/pkg/net/dnsclient_unix.go#L169 to use this custom path.

• patch $GOROOT/src/pkg/net/dnsconfig_unix.go to get name servers by running getprop net.dns1 and getprop net.dns2 .
