i try to optimize my Android Application code using Proguard with eclipse ADT v21.1.0-569685 on MAC.
i used project->Android Tools->export asigned Application package option for signing with my private certificate,on finish of signing i got following error,

How to solve the above issue?
In prouard.project file I read
If your project uses WebView with JS, uncomment the following and
specify the fully qualified class name to the JavaScript interface
class:
I have used webview in two activity with WebAppInterface.java class.How to do above statement?
Referring resource name like "#string/on_click_handler_name", in android:onClick attribute of your layout file is ok. However, proguard cannot resolve these references.
Check http://android.okhelp.cz/proguard-parseexception-expecting-class-member-name-before/ for more details.
Find corresponding value of #string/tha_lf_et_todate_onclick in your string.xml and update :
android:onClick="#string/tha_lf_et_todate_onclick"
to
android:onClick="onClickXXX"
in your layout file.
For the second question,
uncomment that piece of code, and replace "fqcn.of.javascript.interface.for.webview"
with the class's fully qualified name.

I am enabling proguard like this when I try to build apk in release mode I am getting error code 1 in eclipse Juno. if I use same code in android studio I can able to build release apk . if I reverse engineer the apk which got from android studio I can read the entire code so how I can obfuscate the code
to work with proguard you need to just enable proguard using gradil script .
open gradil file and enable minifiable true and try to sign your application
I have problem with proguard, I have tried with many possible solutions but still does not solve my problem.
The only information I get from console is
Proguard returned with error code 1. See console
nothing more, this is a really bad error message I ever met.
I have set
proguard.config=proguard-project.txt
and nothing in proguard-project.txt that I believe only a couple of comments.

After couples of hours finding the solution, I found the solution. I just moved the proguard.jar to another directory which there is no space in the path, then I edited the proguard.bat in /bin folder to that directory. Eventually, the proguard is running fine and give me the error log that I expected.
Sample script.
#ECHO OFF
REM Start-up script for ProGuard -- free class file shrinker, optimizer,
REM obfuscator, and preverifier for Java bytecode.
rem Change current directory and drive to where the script is, to avoid
rem issues with directories containing whitespaces.
cd /d %~dp0
IF EXIST "%PROGUARD_HOME%" GOTO home
SET PROGUARD_HOME=..
:home
java -jar C:\bin\proguard.jar %*
You have commented text file, it should be like this :

I can't export my project with proguard, I get this error and out of solutions..
I don't know where is this argument number 12 ...
[2013-05-14 17:38:39 - LiveWallpaper] Proguard returned with error code 1. See console
[2013-05-14 17:38:39 - LiveWallpaper] Error: Unknown option '(' in argument number 12
my project.properties:
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=proguard.cfg
# Project target.
target=android-13
and my proguard.cfg is empty.
Thanks!
Ok so I found the solution using
Proguard ParseException with Default proguard.cfg on Android
My problem was the my workplace directory folder name was with a "(" character .. so I moved it to another directory without whitespaces or "(" and it solved it.
I am using proguard to obfuscate the code.
I am getting the following error in console
Proguard returned with error code 1. See console

How to solve this?
I fixed it by adding this in my proguard-project.txt
-keep public class * extends com.phonegap.api.Plugin
-keep public class org.apache.cordova.DroidGap
-keep public class org.apache.cordova.**
-libraryjars /Users/Nasir/Desktop/libs/commons-codec.jar
-dontwarn android.webkit.*
You can add the following to your proguard-project.txt. It worked for me on Cordova (PhoneGap) 2.1:
-keep public class * extends com.phonegap.api.Plugin
-keep public class * extends org.apache.cordova.api.Plugin
-keep public class org.apache.cordova.DroidGap
-keep public class org.apache.cordova.**
-libraryjars libs/commons-codec-1.7.jar
-dontwarn android.webkit.*
-dontwarn org.apache.**
