go version: go version go1.2.1 linux/amd64

1. compile a Go program with GOARCH=arm, GOOS=linux and GOARM=7 that uses
"net.ResolveUDPAddr("udp", someServer)"
2. put it onto an Android device and execute it using shell (only works in internal
memory afaik)

What happened?
err is set to "error reading DNS config: open /etc/resolv.conf: no such file or
directory"

What should have happened instead?
Go should resolve the address

Please provide any additional information below.
This is because /etc/resolv.conf does not exist on Android. Instead, the DNS can be
retrieved using the shell with command "getprop net.dns1".

I'm also open for any workarounds (that don't involve a complete alternative dns
implementation/library).

Comment 2:

I believe this issue has been addressed. We have support for android/arm in the std lib
and a passing builder on the dashboard.

Labels changed: added release-go1.4, removed release-none.

Status changed to Fixed.

Not yet. at least the net and os/user packages still need android specific
handling.

Status changed to Accepted.

Comment 6:

We have a working builder, so I am marking this as fixed. The intended android support
from the Go team assumes the use of cgo, as we have to use the Android NDK linker to
build Android apps.
I have filed issue #8877 and issue #8878 to track cgo-less net support and os/user support.

Status changed to Fixed.
