-libraryjars /libs/org.apache.httpcomponents.httpclient_4.2.1.jar
-libraryjars /libs/signpost-commonshttp4-1.2.1.1.jar
-libraryjars /libs/signpost-core-1.2.1.1.jar
-libraryjars /libs/signpost-jetty6-1.2.1.1.jar
-libraryjars /libs/twitter4j-core-2.1.6.jar

In the standard Android builds (Ant, Eclipse, Gradle), don't specify -libraryjars or -injars, since the build scripts will already specify those for you. Just make sure you add all necessary library jars to the libs directory, as usual, so the build scripts will include them.

In Eclipse, libraries may need to be marked as Exported.

There is no HttpCore in your libs.

Please import HttpCore

This link is HttpCore 4.1, You can search HttpCore 4.2 or 4.3 if you want.

In the future, when you import a library please ensure that you import the relevant library

Add the following lines to you proguard-project.txt file:

-keep class org.apache.http.** {
    *;
}

I would also suggest you to use repackaged version of HttpClient for Android instead of original HttpClient jar to avoid class loading collisions with the version bundled with Android. But as far as I can see you'll also need to rebuild Signpost HttpClient module to use ch.boye.httpclientandroidlib package instead of org.apache.http (and don't forget to update package name in proguard-project.txt as well).

Import the package on your bundle

Import-Package: org.apache.http.params
