Using proguard to generate apk with the common libaries

I have the following library in my project
As jar:
httpcore-4.3.1.jar
httpmime-4.3.2.jar
libGoogleAnalyticsServices.jar (latest GA version)
As import project
facebookSDK 3.6
I have added the following to proguard-project.txt
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
-keep class org.apache.**
-keep interface org.apache.**
-keep class com.facebook.** { *; }
-keepattributes Signature
-dontwarn org.apache.**
and in the properties
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
It can generate the signed apk, but it will throw exception
NoSuchMethodError: org.apache.http.params.HttpConnectionParams...
How to fix the problem? As I have add the keep class already? Thanks for helping

put { *; } at the end of -keep interface org.apache.** and those -keep rules

Proguard Returned With Error Code 1 Without Any Specific Information

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.
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.

# This is a configuration file for ProGuard.

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 %*

Android Proguard - Internet connectivity issue after exporting application

I am currently exporting application while proguard is enabled and the issue is that the application works fine but application is deployed without proguard but if exported and deployed while proguard is enabled the application gives error that internet is not connected. following is the proguard file text
-dontshrink
-dontoptimize
-dontwarn com.example.google.tv.**
-dontwarn android.support.**
-dontwarn org.ksoap.**
-dontwarn android.view.**
-dontwarn android.graphics.**

If I remove
-dontwarn android.view.**
-dontwarn android.graphics.**
-dontwarn android.content.**
-dontwarn android.util.**
then here is the log that I receive

You should remove the package org.xmlpull.v1 from your libraries. It is already present in the Android runtime (which gets precedence anyway). Adding duplicate packages increases the application size at best, and it can cause versioning problems at worst. In this case, ProGuard detects some dependency conflicts.
Note that is "ProGuard", not "Progaurd".

proguard.ParseException: Expecting class member name before '#' in Android Eclipse ADT

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.

Android ant build.xml with proguard does not build in release

I have the following project setup:
Two libraries 'commoncomponents' and 'libs' that both have some activities defined e.g. with a webview and dialog helper classes.
Then there is my 'application library' which contains the app code which in turn is
referenced by the App 'Free' and the App 'Full'.
I have enabled proguard with the following additional entry
-keepclassmembers class **.R$* {
public static <fields>;
}
However the build process fails when launching ant with the release target and proguard
complains that the R$string classes are missing
If I call 'ant release' on 'commoncomponents', 'libs' or 'application library' projects proguard succeeds,
But when I launch it on either the 'app free' or 'app full' this errormessage is comes up:

I've searched the web for the issue and I found a lot of posts especially here on stackoverflow, but none helped me solve the issue yet, hope someone is so kind to assist although this is my very first question.
Thanks

It turned out that the application library build file had the proguard obfuscation switched on, by switching it off all symbols were found when building the free and full application stubs.
