created issue #1

May 27, 2018 03:35PM

When all the launch options are selected for a particular destination and the application is run, then the application crashes by throwing an IllegalArgumentException while navigating immediately between two destinations. But, the issue does not arise when only one or two launch options (in any combination) are selected.

DETAILS:-
The destination home is an activity with a NavHostFragment (FirstFragment.kt) which initially navigates to the second destination (SecondActivity.kt), then immediately comes back to the FirstFragment, and then navigates to third destination (FirstPopupFragment.kt). (Navigation can be observed in the attached screen-record).

please run emulator with the following options and post the output here, thanks!
/path/to/emulator -verbose -show-kernel -avd <avename> -feature -ModemSimulator

the above command line will not use modem, just to see if it is related.

Marked as fixed.

Yes,it worked.

Attaching the log below.

I'm getting the same error on my Ryzen 1800X on OpenSUSE Tumbleweed:

"qemu-system-x86_64: -chardev socket,port=38379,host=::1,nowait,nodelay,ipv6,id=modem: address resolution failed for ::1:38379: Name or service not known"

Adding the "-feature -ModemSimulator" flags worked around the issue for me.

Hi truefalsetrue101@, could you try look at your /etc/hosts file on your machine? On my machine, it looks like

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

If ::1 localhost is missing, that probably explains why "Name or service was not known".

I have that entry. Here's my entire /etc/hosts (my IP and hostname have been replaced with "xxx"):

#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#    
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#

127.0.0.1       localhost

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix

RE#7

bohu@, any idea why this call would fail on host? I am also guessing maybe it has to do with the /etc/resolv.conf on host.

    if ((rc = getaddrinfo(addr, port, &ai, &local)) != 0) {
        error_setg(errp, "address resolution failed for %s:%s: %s", addr, port,
                   gai_strerror(rc));
        goto err;
    }

"I'm getting the same error on my Ryzen 1800X on OpenSUSE Tumbleweed"

could be related to the linux flavor regarding address resolution.
my machine has almost the same config, and the getaddrinfo just works.
I wonder if there is some sys log you can put up here regarding that error.

[Deleted User] <[Deleted User]> #10Sep 27, 2018 09:34AM

It seems linux hosts have lots of problem regarding this, might be better use different ways to hook up the modem.

OpenSUSE Tumbleweed has a toggle in it's network settings for "Enable IPv6". I don't have IPv6 on my internet connection and none of my local devices need it, so I usually leave it disabled.

I tried enabling it and viola, the emulator is starting for me again (without needing the ModemSimulator flag).

It looks like that toggle adds net.ipv6.conf.all.disable_ipv6 = 1 to /etc/sysctl.conf.

Thanks #11
that is very helpful information.

I was surprised that emulator does not even try ipv4 when ipv6 failed;

error_setg should be just a warning instead of quitting.

"I tried enabling it and viola, the emulator is starting for me again (without needing the ModemSimulator flag)".

Yes,turning IPv6 on worked for me too.
