Following the directions found here "Testing Local Web Sites with the Android Emulator", I've been successful up until Make your changes to the hosts file and then save it back to the AVD. In other words, I'm unable to push my modified host file back to the AVD. The directions in the article are for Mac, so I've converted the command lines to windows.
The Mac command referenced in the article is this...
$ ~/Library/Android/sdk/platform-tools/adb -s emulator-5554 push ~/Desktop/hosts /system/etc/hosts
Which I've translated to Windows as this...
$ adb –s emulator-5554 push C:\Users\<username>\Downloads\hosts /system/etc/hosts
Note:
- for the windows command, I'm already in the C://platform-tools/ directory, where adb lives
- The in my local path is a placeholder for my actual username
- The modified host file does exist at the path specified.
When I run the adb command to push the host file back to the AVD, the file is not pushed and I see this output in the terminal...
C:\Users\<username>\AppData\Local\Android\sdk\platform-tools>adb -s emu
lator-5554 push C:\Users\<username>\Downloads\hosts /system/etc/hosts

-a - directs adb to listen on all interfaces for a c
onnection
-d - directs command to the only connected USB devic
e
returns an error if more than one USB device is
present.
-e - directs command to the only running emulator.
returns an error if more than one emulator is r
unning.
-s <specific device> - directs command to the device or emulator with
the given
serial number or qualifier. Overrides ANDROID_S
ERIAL
environment variable.
-p <product name or path> - simple product name like 'sooner', or
a relative/absolute path to a product
out directory like 'out/target/product/sooner'.
If -p is not specified, the ANDROID_PRODUCT_OUT
environment variable is used, which must
be an absolute path.
-H - Name of adb server host (default: localhost)
-P - Port of adb server (default: 5037)
devices [-l] - list all connected devices
('-l' will also list device qualifiers)
connect <host>[:<port>] - connect to a device via TCP/IP
Port 5555 is used by default if no port number
is specified.
disconnect [<host>[:<port>]] - disconnect from a TCP/IP device.
Port 5555 is used by default if no port number
is specified.
Using this command with no additional arguments
will disconnect from all connected TCP/IP devic
es.
device commands:
adb push <local>... <remote>
- copy files/dirs to device
adb pull [-a] <remote>... <local>
- copy files/dirs from device
(-a preserves file timestamp and mode)
adb sync [ <directory> ] - copy host->device only if changed
(-l means list but don't copy)
adb shell [-e escape] [-n] [-Tt] [-x] [command]
- run remote shell command (interactive shell if
no command given)

t '~')
(-n: don't read from stdin)
(-T: disable PTY allocation)
(-t: force PTY allocation)
(-x: disable remote exit codes and stdout/stder
r separation)

adb forward --remove <local> - remove a specific forward socket connection
adb forward --remove-all - remove all forward socket connections
adb reverse --list - list all reverse socket connections from device
adb reverse <remote> <local> - reverse socket connections
reverse specs are one of:

localreserved:<unix domain socket name>
localfilesystem:<unix domain socket name>
adb reverse --no-rebind <remote> <local>
- same as 'adb reverse <remote> <local>' but fail
s
if <remote> is already reversed.
adb reverse --remove <remote>
- remove a specific reversed socket connection
adb reverse --remove-all - remove all reversed socket connections from dev
ice
adb jdwp - list PIDs of processes hosting a JDWP transport
adb install [-lrtsdg] <file>
- push this package file to the device and instal
l it
(-l: forward lock application)
(-r: replace existing application)
(-t: allow test packages)
(-s: install application on sdcard)
(-d: allow version code downgrade (debuggable p
ackages only))
(-g: grant all runtime permissions)
adb install-multiple [-lrtsdpg] <file...>
- push this package file to the device and instal
l it
(-l: forward lock application)
(-r: replace existing application)
(-t: allow test packages)
(-s: install application on sdcard)
(-d: allow version code downgrade (debuggable p
ackages only))
(-p: partial application install)
(-g: grant all runtime permissions)
adb uninstall [-k] <package> - remove this app package from the device
('-k' means keep the data and cache directories
)
adb bugreport [<zip_file>] - return all information from the device
that should be included in a bug report.
adb backup [-f <file>] [-apk|-noapk] [-obb|-noobb] [-shared|-noshared] [-all]
[-system|-nosystem] [<packages...>]
- write an archive of the device's data to <file>
.
If no -f option is supplied then the data is wr
itten
to "backup.ab" in the current directory.
(-apk|-noapk enable/disable backup of the .apks
themselves
in the archive; the default is noapk.)
(-obb|-noobb enable/disable backup of any insta
lled apk expansion
(aka .obb) files associated with each applic
ation; the default

(-shared|-noshared enable/disable backup of the
device's
shared storage / SD card contents; the defau
lt is noshared.)
(-all means to back up all installed applicatio
ns)
(-system|-nosystem toggles whether -all automat
ically includes
system applications; the default is to inclu
de system apps)
(<packages...> is the list of applications to b
e backed up. If
the -all or -shared flags are passed, then t
he package
list is optional. Applications explicitly g
iven on the
command line will be included even if -nosys

ordinarily cause them to be omitted.)

archive

adb reboot [bootloader|recovery]

Note: you should not automatically start a PPP connection.
<tty> refers to the tty for PPP stream. Eg. dev:/dev/omap_csmi_tty1
[parameters] - Eg. defaultroute debug dump local notty usepeerdns
adb sync notes: adb sync [ <directory> ]
<localdir> can be interpreted in several ways:
- If <directory> is not specified, /system, /vendor (if present), /oem (if pre
sent) and /data partitions will be updated.
- If it is "system", "vendor", "oem" or "data", only the corresponding partiti
on
is updated.
internal debugging:
adb reconnect Kick current connection from host side and make
it reconnect.
adb reconnect device Kick current connection from device side and ma
ke it reconnect.
environment variables:
ADB_TRACE - Print debug information. A comma separated list
of the following values
1 or all, adb, sockets, packets, rwx, usb, sync
, sysdeps, transport, jdwp
ANDROID_SERIAL - The serial number to connect to. -s takes prior
ity over this if given.
ANDROID_LOG_TAGS - When used with the logcat option, only these de
bug tags are printed.
Which tells me something went wrong with the syntax. As far as I can tell, the syntax is correct though. Any ideas?
