Proguard Android salta jar esterno

Ho provato a utilizzare Proguard nel mio progetto Android, ho installato Proguard utilizzando la riga di comando 'android update project/path/to/project' e il file proguard.cfg è stato creato nella directory root del progetto. (Nel mio Eclipse con sdk Android 2.3, quando creo un nuovo progetto, il file proguard.cfg non viene creato automaticamente quindi devo aggiungerlo manualmente usando la riga di comando).Proguard Android salta jar esterno

quando esporto il progetto, ho ottenuto le seguenti errori

ho provato alcune soluzioni trovate sul web, con l'aggiunta di opzione '-libraryjars', es:

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

ma non aiuterà.

Qualche soluzione?

I vostri barattoli di libreria si riferiscono a più giare di libreria (Mortbay, SLF4J, Apache Commons Logging, Log4j, ...) Aggiungendo questi vasi con opzioni extra '-libraryjars' è necessario risolvere il problema.

Se sei assolutamente sicuro che il tuo codice non usi queste librerie, puoi specificare "-ignorewarnings" o "-dontwarn", ad es.

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

Ciao Eric, grazie per la soluzione. Ho aggiunto -libraryjars alla libreria che hai indicato: i messaggi di avviso spariscono ma quando eseguo l'app force chiusa, dai messaggi di log ho trovato 'classnotfound exception' su twitter4j –

prova ad aggiungere la classe che ha causato "ClassNotFoundException" per le opzioni "keep" '-keep public class com.example.Foo {public protected *; } ' –

quale percorso useresti nell'opzione -libraryjars? Non riesco a capirlo. – cottonBallPaws
