问题:

Looking for a ProGuard configuration for Guava that will obfuscate and optimize, as the default one that is provided on the website does not.

Not only that I cannot get it to export my apk, I keep getting:

Warning: com.google.common.collect.MinMaxPriorityQueue:      can't find referenced field 'int UNSET_EXPECTED_SIZE' in class       com.google.common.collect.MinMaxPriorityQueue$Builder You should check if you need to specify additional program jars.

回答1:

As of Guava 17.0, this is what I needed in ProGuard config:

-dontwarn javax.annotation.** -dontwarn javax.inject.** -dontwarn sun.misc.Unsafe

Otherwise build fails with warnings like:

Warning: com.google.common.base.Absent:     can't find referenced class javax.annotation.Nullable

(That's because Guava uses annotations that are not part of Android runtime (android.jar). In this case it's fine to just mute the warnings.)

If you are using Gradle as the build tool, the above proguard-project.txt and the following in build.gradle produces an optimised and obfuscated APK while using Guava.

buildTypes {     release {         minifyEnabled true         proguardFile file('proguard-project.txt')         proguardFile getDefaultProguardFile('proguard-android-optimize.txt')     } }

Alternatively you can include dependecy to jsr305.jar in build.gradle dependencies:

compile 'com.google.code.findbugs:jsr305:2.0.2'

...with only -dontwarn sun.misc.Unsafe in ProGuard config, but I preferred using -dontwarn also for the javax stuff.

回答2:

Now that Guava 19.0 is released, I found that I had to add these rules.

-keep class com.google.j2objc.annotations.** { *; } -dontwarn   com.google.j2objc.annotations.** -keep class java.lang.ClassValue { *; } -dontwarn   java.lang.ClassValue -keep class org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement { *; } -dontwarn   org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

回答3:

I had to add the following lines to my proguard rules file when upgrading from 23.4-android to 23.5-android:

-dontwarn afu.org.checkerframework.** -dontwarn org.checkerframework.**

The proguard warnings that I saw from the update (before adding new rules) are listed below for reference:

For those interested, the full ruleset I have for guava currently is:

# Guava (official) ## Not yet defined: follow https://github.com/google/guava/issues/2117 # Guava (unofficial) ## https://github.com/google/guava/issues/2926#issuecomment-325455128 ## https://stackoverflow.com/questions/9120338/proguard-configuration-for-guava-with-obfuscation-and-optimization -dontwarn com.google.common.base.** -dontwarn com.google.errorprone.annotations.** -dontwarn com.google.j2objc.annotations.** -dontwarn java.lang.ClassValue -dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement # Added for guava 23.5-android -dontwarn afu.org.checkerframework.** -dontwarn org.checkerframework.**

回答4:

For Guava 20.0 you need to add also:

# Guava 20.0 -dontwarn com.google.errorprone.annotations.CanIgnoreReturnValue -dontwarn com.google.errorprone.annotations.concurrent.LazyInit -dontwarn com.google.errorprone.annotations.ForOverride

回答5:

This message suggests the following workaround:

-dontwarn com.google.common.collect.MinMaxPriorityQueue

I'd like to think that Proguard could be changed to make this unnecessary, but we haven't checked with its owners.

回答6:

Total proguard rule for guava 20.0. For now the latest guava 21 does not support android.

-dontwarn com.google.common.base.** -keep class com.google.common.base.** {*;} -dontwarn com.google.errorprone.annotations.** -keep class com.google.errorprone.annotations.** {*;} -dontwarn   com.google.j2objc.annotations.** -keep class com.google.j2objc.annotations.** { *; } -dontwarn   java.lang.ClassValue -keep class java.lang.ClassValue { *; } -dontwarn   org.codehaus.mojo.
