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了文件 proguard.cfg。（在我的带有 Android 2.3 sdk 的 Eclipse 中，当创建一个新项目时，proguard.cfg 文件不会自动创建，所以我必须使用命令行手动添加它）。

当我导出项目时，出现以下错误

[2011-02-06 09:02:49 - TestProject]       You should check if you need to specify additional program jars.

[2011-02-06 09:02:49 - TestProject]          You may need to specify additional library jars (using '-libraryjars'),
[2011-02-06 09:02:49 - TestProject]          or perhaps the '-dontskipnonpubliclibraryclasses' option.

这些错误消息指向我项目中使用的四个外部 jar

(.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 *;
}

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

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

但这无济于事。

有什么解决办法吗？

您的库 jar 引用了更​​多库 jar（Mortbay、SLF4J、Apache Commons Logging、Log4j，...）添加这些带有额外“-libraryjars”选项的 jar 应该可以解决问题。

如果您绝对确定您的代码不使用这些库，则可以指定“-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.**
