Android Proguard跳过外部jar

时间：2011-02-06 02:27:47

标签： android jar external proguard

我尝试在我的Android项目中使用Proguard，我使用命令行'android update project / path / to / project'设置Proguard，并在项目的根目录中创建文件proguard.cfg。 （在使用Android 2.3 sdk的Eclipse中，创建新项目时，不会自动创建proguard.cfg文件，因此我必须使用命令行手动添加它。）

当我导出项目时，我收到以下错误

这些错误消息指向我项目中使用的四个外部jar

（类路径）

<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 * {

}

-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 *;
}

我通过添加'-libraryjars'选项尝试了一些在网络上找到的解决方案，例如：

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

但它无济于事。

任何解决方案？

答案 0 :(得分：38)

你的图书馆罐子引用了更多的库罐子（Mortbay，SLF4J，Apache Commons Logging，Log4j，......）添加这些带有额外“-libraryjars”选项的罐子可以解决这个问题。

如果您完全确定您的代码不使用这些库，您可以指定'-ignorewarnings'或'-dontwarn'，例如

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