# As of August 11, 2016, obfuscation was tested and passed on the trybots,
# saving us 660kb on our .dex size and 53kb memory/process. Enable obfuscation
# as soon as Crash supports ReTrace's deobfuscation of stack traces.
#
# To enable obfuscation, remove the -keepnames rule for
# com.google.android.apps.chrome.** and org.chromium.**, and uncomment the
# following two lines:
# -renamesourcefileattribute PG
# -repackageclasses ""

# Disable obfuscation for the following two packages.
-keepnames,allowoptimization class com.google.android.apps.chrome.**,org.chromium.** {
  *;
}

# The following chart was created on July 20, 2016, to decide on 3 optimization
# passes.
# optimization passes | time | .dex size | dirty memory per process
