Android Proguard跳过外部jar

我试图在我的Android项目中使用Proguard,我使用命令行'android update project / path / to / project'来设置Proguard,并且在项目的根目录中创build了proguard.cfg文件。 (在我的Eclipse与Android 2.3 sdk,当创build一个新的项目,proguard.cfg文件不会自动创build,所以我必须使用命令行手动添加它)。

当我导出项目时,我得到以下错误

这些错误消息指向我的项目中使用的四个外部jar子

(的.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/signpost-core-1.2.1.1.jar"/> <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/signpost-jetty6-1.2.1.1.jar"/> <classpathentry kind="lib" path="/Users/lorensiuswlt/Android/android-sdk-mac_x86/libs/Twitter/twitter4j-core-2.1.6.jar"/> 

这是我的proguard.cfg文件

 -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* -keep public class * extends android.app.Activity -keep public class * extends android.app.Application -keep public class * extends android.app.Service -keep public class * extends android.content.BroadcastReceiver -keep public class * extends android.content.ContentProvider -keep public class * extends android.app.backup.BackupAgentHelper -keep public class * extends android.preference.Preference -keep public class com.android.vending.licensing.ILicensingService -keepclasseswithmembernames class * { native <methods>; } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet); } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet, int); } -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); } -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; } 

我已经尝试了一些在网上find的解决scheme,通过添加'-libraryjars'选项,例如:

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

但它不会帮助。

任何解决scheme

你的图书馆jar子指的是更多的图书馆jar子(Mortbay,SLF4J,Apache Commons Logging,Log4j,…)添加这些jar子额外的'-libraryjars'选项应该解决这个问题。

如果您确信您的代码不使用这些库,则可以指定“-ignorewarnings”或“-twtwarn”,例如

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