Classes with corrupt debug information cannot be dexed, but +# classes with *no* debug information can be. There's no way to configure Proguard to +# delete debug information on a per-class basis, so we need this special extra step for +# stripping debug information only from those classes for which the Proguard bug is +# encountered. +# +# Currently, this pass is applied to all bundled library jars for which we are not +# compiling the source. This is slightly more than is strictly necessary to work around +# the Proguard bug, but such debug information is of negligible value and stripping it +# too slightly simplifies the makefile and saves us a handful of kilobytes of binary size. +# +# Configuring Proguard to do nothing except strip metadata is done by having it run only +# the obfuscation pass, but with a configuration that prevents it from renaming any classes. +# It then attempts to delete class metadata, so we further configure it not to do so for +# anything except the problematic debug information. + +# Run only the obfuscator. +-dontoptimize +-dontshrink +-dontpreverify +-verbose + +# Don't rename anything. +-keeppackagenames + +# Seriously, don't rename anything. +-keep class * +-keepclassmembers class * { + *; +} + +# Don't delete other useful metadata. +-keepattributes Exceptions,InnerClasses,Signature,Deprecated,*Annotation*,EnclosingMethod + +# Don't print spurious warnings from the support library. +# See: http://stackoverflow.com/questions/22441366/note-android-support-v4-text-icucompatics-cant-find-dynamically-referenced-cl +-dontnote android.support.** +-dontwarn android.support.** |
