Add a script for configuring adb for working remotely.

tools/android/adb_remote_setup.sh

+#!/bin/bash
+
+# URL from which the latest version of this script can be downloaded.
+script_url="http://src.chromium.org/svn/trunk/src/tools/android/adb_remote_setup.sh"
+
+# Replaces this file with the latest version of the script and runs it.
+update-self() {
+  local script="${BASH_SOURCE[0]}"
+  local new_script="${script}.new"
+  local updater_script="${script}.updater"
+  curl -f -o "$new_script" "$script_url" || return

Macs don't ship with curl, so we should have an error message if not present.

Ok, I can add that. Though this stackoverflow answer seems to indicate that macs
do come with curl

OK, never mind then, I must've confused it with wget.

+  chmod +x "$new_script" || return
+
+  # Replace this file with the newly downloaded script.
+  cat > "$updater_script" << EOF
+#!/bin/bash
+if mv "$new_script" "$script"; then
+  rm -- "$updater_script"
+else
+  echo "Note: script update failed."
+fi
+ADB_REMOTE_SETUP_NO_UPDATE=1 exec /bin/bash "$script" $@
+EOF
+  exec /bin/bash "$updater_script" "$@"
+}
+
+if [[ "$ADB_REMOTE_SETUP_NO_UPDATE" -ne 1 ]]; then
+  update-self "$@" || echo 'Note: script update failed'
+fi
+
+if [[ $# -ne 2 ]]; then
+  cat <<'EOF'
+Usage: adb_remote_setup.sh REMOTE_HOST REMOTE_ADB
+
+Configures adb on a remote machine to communicate with a device attached to the
+local machine. This is useful for installing APKs, running tests, etc while
+working remotely.
+
+Arguments:
+  REMOTE_HOST  hostname of remote machine
+  REMOTE_ADB   path to adb on the remote machine
+EOF
+  exit 1
+fi
+
+remote_host="$1"
+remote_adb="$2"

Could you make this default to just "adb"?  I think that should work when adb is
in the path on the remote machine.

[newt (away), 2014/02/07 02:49:48]

I tried this, but it doesn't work for me, since .bashrc doesn't get sourced when
running the SSH command on the remote machine. Does something like "ssh laptop
'adb shell ps'" work for you?

[aelias_OOO_until_Jul13, 2014/02/07 03:00:42]

Yes, it does work.  That's probably because I have the line ". ~/.bashrc" in my
.bash_profile, which I believe is sourced in non-interactive shells.  I guess
for folks who don't, you could have the command be:

ssh "$remote_host" ". ~/.bashrc; $remote_adb kill-server"

?

+
+if which kinit >/dev/null; then
+  # Allow ssh to succeed without typing your password multiple times.
+  kinit -R || kinit
+fi
+
+# Kill the adb server on the remote host.
+ssh "$remote_host" "$remote_adb kill-server"
+
+# Start the adb server locally.
+adb start-server
+
+# Forward various ports from the remote host to the local host:
+#   5037: adb
+#   8001: http server
+#   9031: sync server
+#   10000: net unittests
+#   10201: net unittests
+ssh -C \
+    -R 5037:localhost:5037 \
+    -L 8001:localhost:8001 \
+    -L 9031:localhost:9031 \
+    -R 10000:localhost:10000 \
+    -R 10201:localhost:10201 \
+    "$remote_host"
