Warning: library class android.net.http.AndroidHttpClient extends or implements program class org.apache.http.client.HttpClient

Question

I am getting these weird error from proguard while exporting android app. I have edited config file. But I couldn't find what the remaining errors are.

I have added external Jars, configured -dontwarn , now I couldn't find the remaining issues.

[2013-11-22 17:13:31 - MyProject]       You should check if you need to specify additional program jars.

[2013-11-22 17:13:31 - MyProject]          You must avoid such dependencies, since the program classes will

My ProGuard Config file:

# 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 {

Answer 1

Try adding this in the proguard config file.

-libraryjars libs\android-support-v4.jar
-libraryjars <java.home>\lib\rt.jar

-dontwarn org.apache.commons.**

Also, why do you have -libraryjars /libs/picasso-2.0.1.jar twice?
