ProGuard configuration for Guava with obfuscation and optimization

Question

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.

This is more a Proguard question than anything else, I think? — Louis Wasserman, Feb 02 '12 at 21:48
More of a guava question actually. Something in Guava is causing that Class to throw a warning. The answer listed should resolve the issue. — Slinkkay, Feb 02 '12 at 22:46
Ah. I was paying more attention to the first part of the issue: "a configuration that will obfuscate and optimize." — Louis Wasserman, Feb 02 '12 at 22:46
Yeah, two-part questions are quite annoying, but in this case, both parts are about proguard. — Kevin Bourrillion, Feb 03 '12 at 00:55

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.

By the way, if anyone is concerned about the effect of Guava dependency on **APK size**, don't be. [Simple testing showed](http://stackoverflow.com/questions/14978699/#comment31438519_14979043) that without ProGuard Guava increases APK size by about 700KB, but with ProGuard the increase is negligible. — Jonik, Jan 05 '14 at 16:28
I'm using Guava `com.google.guava:guava:22.0-android` and your suggestion doesn't work on my proguard configuration. Any idea? — Eftekhari, Jul 09 '17 at 09:18

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.**

One of the engineers who built R8 (Stephan Herhut) listed the following rules for the latest Guava (25.0-android) in this session from Google I/O 2018:

-dontwarn afu.org.checkerframework.**
-dontwarn org.checkerframework.**
-dontwarn com.google.errorprone.**
-dontwarn sun.misc.Unsafe
-dontwarn java.lang.ClassValue

The video also includes a short explanation of the rules (first 3 are static analysis annotation frameworks, last 2 are unavailable classes on Android which are protected by runtime checks in Guava).

I spoke with Stephan after the session and he said these will hopefully be included in the Guava documentation in the future or better yet in the consumerProguardFiles of future Guava releases. Here's hoping!

Technically, Stephan's talk used Guava `24.1-android`, but I tested the rules with `25.0-android` and they worked. — ashughes, May 14 '18 at 20:22

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

This message suggests the following workaround:

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

guava's jar files were produced by a java compiler that (unlike javac) kept extra references to private inlined constants in the constant pool of referencing classes in the same source file, which fails only with proguard 4.7, which appears to optimize away the private constant definitions, without optimizing away the references. Future guava jar files will not have such constant pool references, but there's probably a bug in proguard 4.7 that does not manifest with jar files produced by standard javac.

ProGuard will optimize away the constant definition and reference fine, if you tell it to ignore the suspicious reference. In the compiled code, a class is referencing a private field in a different class. In my understanding, such a reference (without accessor methods) is not allowed (JVM specs 2.17.3). Other programs, like the JVM, may happen to be more forgiving due to lazy resolution. I'm still curious which compiler is producing this code. – Eric Lafortune Apr 08 '12 at 11:53

These proguard-rules worked for me: guava 23.3-android

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue
-dontwarn com.google.common.util.concurrent.FuturesGetChecked**
-dontwarn javax.lang.model.element.Modifier
