Android Proguard skip jar externo

Intenté usar Proguard en mi proyecto Android, configuré Proguard usando la línea de comando 'android update project/path/to/project' y el archivo proguard.cfg se creó en el directorio raíz del proyecto. (En mi Eclipse con Android 2.3 sdk, cuando creo un nuevo proyecto, el archivo proguard.cfg no se crea automáticamente, así que tengo que agregarlo manualmente usando la línea de comandos).Android Proguard skip jar externo

cuando la exportación del proyecto, tengo los siguientes errores

Estos mensajes de error apuntan a cuatro tarros externos utilizados en mi proyecto

(.classpath)

<classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/signpost-commonshttp4-1.2.1.1.jar"/>

     <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar"/>

Aquí es mi archivo proguard.cfg

-keep class * implements android.os.Parcelable {

que he probado algunas soluciones que se encuentran en la web mediante la adición de la opción '' -libraryjars, por ejemplo:

-libraryjars /Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar

pero no va a ayudar.

¿Alguna solución?

Los archivos de su biblioteca hacen referencia a aún más archivos de biblioteca (Mortbay, SLF4J, Apache Commons Logging, Log4j, ...) Agregar estos archivos con opciones adicionales '-libraryjars' debería resolver el problema.

Si está absolutamente seguro de que su código no utiliza estas bibliotecas, puede especificar '-ignorewarnings' o '-dontwarn', p. Ej.

-dontwarn org.mortbay.** 
-dontwarn org.slf4j.** 
-dontwarn org.apache.log4j.** 
-dontwarn org.apache.commons.logging.** 
-dontwarn org.apache.commons.codec.binary.**

Hola Eric, gracias por la solución. He agregado -ibraryjars a la biblioteca que ha señalado: los mensajes de advertencia desaparecen pero cuando ejecuto la aplicación forzar cerrada, de los mensajes de registro encontré 'classnotfound exception' en twitter4j –

intente agregar la clase que causó la "ClassNotFoundException" a las opciones "keep" '-keep public class com.example.Foo {public protected *; } ' –

¿qué ruta utilizarías en la opción -libraryjars? Parece que no puedo entender eso. – cottonBallPaws
