In Android, I have proguard with the following settings.
-dontpreverify
# Hold onto the mapping.text file, it can be used to unobfuscate stack traces in the developer console using the retrace tool
-printmapping mapping.txt

Some of my library, are directly imported from Java SE (Contains JApplet for example)
How I can exclude them from proguard? Note, I have pinyin4j-2.5.0.jar library in -libraryjars. I thought that's the way to tell proguard, "Hey, this is a library. Don't do anything on it, OK?" But, seems like proguard still trying to process pinyin4j-2.5.0.jar
I'm getting the following errors.

You may need to specify additional library jars (using '-libraryjars').
Warning: there were 6 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile them and try again.
Alternatively, you may have to specify the option

Error: Please correct the above warnings first.
Some of you may comment that for library jars which contain Java SE only methods (like Applet, Swing, ...) cannot be used in Android. Nope. In fact, they run perfectly fine, as long as you consume their non-Java SE-only methods.
The full error log can be downloaded from here : https://www.dropbox.com/s/dns62f7gp6unusg/error-log.txt
If you are sure that these Java SE classes are not used, you can indeed ignore the warnings (as you have found in your own answer). An easier way to specify this:
-dontwarn java.beans.**
-dontwarn java.awt.**
-dontwarn javax.swing.**

It seems that your line

Update
But since the needed classes do not exist on android, you have to ignore these warnings.
But do not generally ignore obfuscation warnings, we had a serious bug (using an obfuscation.map in file), because we ignored all warnings.
I merely avoid the error by

It doesn't work completely out of box yet as I still experience crash in "after proguard generated" APK.
Is pretty hard for me to find out why it crashes, as the code is obfuscate.
If I specific dontobfuscate, I will get another set of problem during generation. A message "Conversion to Dalvik format failed with error 1" pop up without additional information. But, that's another set of different problem.

Ok after having reading proguard manual, and having numerous hit and trials I finally did it by modifying last line of above prguard file to
-keepattributes Annotation, InnerClasses, Signature
and every thing works fine
from proguard
Specifies the generic signature of the class, field, or method. Compilers may need this information to properly compile classes that use generic types from compiled libraries. Code may access this signature by reflection.
and issue is of reflection
proguard is corrupting ie touching classes/interfaces in the Cling lib and you need to prevent that...
you could start here assuming you have a problem with Proguard touching some networking related in the Jetty/Http stack i guess from the content of your error. Wild guess is that its as if the http entity or body cant be handled as implementing the proper interfaces... You want to config proguard to avoid all interfaces in that library and you dont have any "keep interface" directives in your proguard...
For example, are you telling proguard not to touch any of the interfaces in 'org.eclipse.jetty' . You are not doing that and you might want to .
see here
scan proguard manuals for -keepinterface to use with jetty packages implementing the server/http connections in your lib.
know more about the 'cling' packages/interfaces around the internal Client-server and internal networking stack implementations in your library ( looks like it implements jetty for C-S connections on some protocol like http )
build a packages list on the lib's jar/archive to compare to your proguard config. pay special attention to interfaces being used by jetty's server implementation "jar -tf my.jar | sort | uniq" or some such
look at whats been obfuscated by proguard in 'mapping.txt' and in 'seeds.txt' explain here. intersect those packages names from those respective lists with packages & lists assembled above that you did NOT want proguard to mess with. 'seeds' should contain your jetty classes/interfaces. 'mapping' should NOT!
Maybe you could try to add -keepclassmembers in addition to -keep class for package org.fourthline.cling as this:
-keep class org.fourthline.cling.** { *;}
-keepclassmembers class org.fourthline.cling.** { *;}

and tried adding

to proguard-project.txt, but this didnt help.
What am I missing?
hey i had the exact same error i fixed it by adding :
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
to my proguard.cfg
I have the same problem, but using Android Studio. Based on Lary Ciminera's solution, I added
-dontwarn com.google.android.gms.**
to proguard-project.txt.
I fixed it by adding this to proguard-project.txt:
-keep class android.content.pm.PackageInstaller
-keep class android.content.pm.PackageInstaller$SessionInfo
-keep class android.content.pm.PackageManager
-dontwarn android.content.pm.PackageInstaller
-dontwarn android.content.pm.PackageInstaller$SessionInfo
-dontwarn android.content.pm.PackageManager
-keep class android.webkit.WebSettings
-dontwarn android.webkit.WebSettings
Upgrading your target SDK version to at least 21 should fix this problem. PackageInstaller and the associated classes were added in API version 21: https://developer.android.com/reference/android/content/pm/PackageInstaller.html

I've also faced this problem. As there's no official solution in the GA documentation yet, I made up this set of rules:
-keep class com.google.android.gms.analytics.**
-keep class com.google.analytics.tracking.**
-dontwarn com.google.android.gms.analytics.**
-dontwarn com.google.analytics.tracking.**
This skips obfuscation as well, but that should not be a problem for an external libary..
The initial warning indicates that FutureApis invokes File#setReadable(boolean,boolean), which doesn't exist on the target platform that you have specified for your build (apparently android-8 or older). ProGuard can ignore it, but it will be a problem if that code is ever executed on those older platforms. The documentation of Google Analytics specifies that android-7 is sufficient, so presumably ignoring it is fine.
The unexpected error indicates that V4 support class AccessibilityDelegateCompatIcs$1 extends Android class View$AccessibilityDelegate, which doesn't exist on the target platform that you have specified for your build (android-13 or older). In this case, ProGuard really needs that class to properly process the code. With an incomplete class hierarchy, the output would be a mess.
You can solve both problems by specifying a more recent build target in project.properties when compiling your release version. The missing classes and methods will be present in the corresponding android.jar, so ProGuard will have all the information it needs. Since these classes are just runtime library classes, used for compilation/optimization/obfuscation, they won't affect the output.
I ran into the same problem - I was able to suppress errors when creating ank for release - but when the application it falls, in those places where the classes to which swearing obfuscator. At the moment I have not solved this problem. What is interesting is that in debage mode when running the application through Eclipse - and it works perfectly.

after adding
-keep public class com.google.ads.**
to the file, the eclipse console gives still the following error:
Proguard returned with error code 1. See console
Note: there were 160 duplicate class definitions.
Warning: com.google.ads.m: can't find referenced class

Warning: com.google.ads.m: can't find referenced class

You should check if you need to specify additional program jars.
Warning: there were 2 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars').
java.io.IOException: Please correct the above warnings first.

I just added the
-dontwarn com.google.ads.**
to the proguard-project.txt file and the signed apk works fine!
this is recommended (like Eric said before) here: Proguard can't find referenced class com.google.ads.internal.state.AdState
This worked for me on It seems that you need to add these 2 items to the proguard config :
-dontwarn com.google.ads.**
-keep class com.google.ads.** {*;}
-dontwarn com.google.ads.**
here secure the ads class
if you want to secure your class then add com.pkgname.**
It so fell out that I use jacorb.jar and CORBA interfaces in my android app. And when I try obfuscate code using Proguard I get a lot of warnings like this one:
[proguard] Warning: org.jacorb.orb.standardInterceptors.SASComponentInterceptor: can't find referenced
class org.ietf.jgss.Oid
And as the result:
[proguard] Warning: there were 1223 unresolved references to classes or interfaces.
[proguard] You may need to specify additional library jars (using '-libraryjars'),
[proguard] or perhaps the '-dontskipnonpubliclibraryclasses' option.
[proguard] Warning: there were 33 unresolved references to program class member
s.
[proguard] Your input classes appear to be inconsistent.
[proguard] You may need to recompile them and try again.
[proguard] Alternatively, you may have to specify the options
[proguard] '-dontskipnonpubliclibraryclasses' and/or
[proguard] '-dontskipnonpubliclibraryclassmembers'.

How to correct these warnings and build working apk file?

Jacorb appears to depend on JGSS, which is not part of the Android runtime. In theory, JGSS should be specified as a library package. However, since your app already runs fine without JGSS, it's fair to assume that this part of the code is never used. You can then switch off the warnings:
-dontwarn org.ietf.jgss.**
ProGuard will no longer complain about these missing classes and proceed with processing the code. The summary in your console output suggests that there are many classes that are probably similar.
