Setting Flags for Chrome on Android

From: Setting Flags for Chrome on Android

adb shell 'echo "chrome <flags>" > /data/local/tmp/content-shell-command-line'

Remember to quit the app completely and restart for flags to take effect.

Turn off SPDY and use system SSL

# Use these flags
--use-spdy=off --use-system-ssl

Logging: GUI or from the command line.

Visit chrome://net-internals/#capture to enable logging.
Another way to capture network events is by using the command line flag:

--log-net-log=FILENAME [ --net-log-level=NUMBER ]

This will stream the network events directly to a file of your choosing. If you additionally want it to log the network bytes, then pass --net-log-level=0.

Register GMail as protocol handler for mailto: links

# Normally, we would have been happy to type this in the
# URL bar
javascript:window.navigator.registerProtocolHandler("mailto","https://mail.google.com/mail/?extsrc=mailto&url=%s","GMail")

# But this doesn't work (security prefs) and an active
# bug shows that gmail still doesn't do this itself.

# So we need to follow these sequence of steps:

# 1. Enable javascript: links
vim $vimws/../chrome/profiles/personal/Local\ State

# Now search for  "protocol_handler": {  "excluded_schemes": {
# and switch javascript from true to false.
#
# Now relaunch Google Chrome.
# One would have hoped this would have done the trick,
# but it turns out that pasting a javascript: url causes
# a google search so we need to find another way to
# launch a javascript: url.
#
# 2. We'll set up a search engine to launch javascript:
# links.
#
# Visit Preferences -> Manage Search Engines and create
# one to launch "javascript:%s"

# 3. Now, using this search engine, visit
window.navigator.registerProtocolHandler("mailto","https://mail.google.com/mail/?extsrc=mailto&url=%s","GMail")

# You're almost done.

# 4. Disable the javascript: links from working via the
# "Local State" file you edited in step 1.
