【问题描述】：
在 Android 中，我有以下设置。
-dontpreverify
# Hold onto the mapping.text file, it can be used to unobfuscate stack traces in the developer console using the retrace tool
-printmapping mapping.txt
# Keep line numbers so they appear in the stack trace of the develeper console
-keepattributes SourceFile,LineNumberTable
# The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle.
-optimizations !code/simplification/arithmetic
# Activities, services and broadcast receivers are specified in the manifest file so they won't be automatically included
-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
# Custom view components might be accessed from your layout files
-keep public class * extends android.view.View {
public <init>(android.content.Context);
public <init>(android.content.Context, android.util.AttributeSet);
public <init>(android.content.Context, android.util.AttributeSet, int);
public void set*(...);
}
# event handlers can be specified in the layout files e.g. android:onClick="nextButton_onClick", I borrowed this method name notation from .NET
-keepclassmembers class * extends android.app.Activity {
public void *_*(android.view.View);
}
# Parcelable implementations are accessed by introspection
-keepclassmembers class * implements android.os.Parcelable {
static android.os.Parcelable$Creator CREATOR;
}
# You might want to keep your annotations
-keepattributes *Annotation*
# I use Google Guava in my app
# see http://code.google.com/p/guava-libraries/wiki/UsingProGuardWithGuava
-libraryjars libs/google/jsr305-1.3.9.jar;libs/pinyin4j/pinyin4j-2.5.0.jar
-dontwarn sun.misc.Unsafe
-keepclasseswithmembers class com.google.common.base.internal.Finalizer{
<methods>;
}
我的一些库，是直接从 Java SE 导入的（例如包含 JApplet）
如何将它们从 proguard 中排除？注意，我在-libraryjars 中有pinyin4j-2.5.0.jar 库。我想这就是告诉 proguard 的方式，“嘿，这是一个图书馆。不要在上面做任何事情，好吗？”但是，似乎 proguard 仍在尝试处理 pinyin4j-2.5.0.jar
我收到以下错误。

You should check if you need to specify additional program jars.
Warning: there were 333 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars').
Warning: there were 6 unresolved references to program class members.
Your input classes appear to be inconsistent.
You may need to recompile them and try again.
Alternatively, you may have to specify the option
'-dontskipnonpubliclibraryclassmembers'.
Error: Please correct the above warnings first.
你们中的一些人可能会评论说，对于包含 Java SE 的库 jar，只有方法（如 Applet、Swing 等）不能在 Android 中使用。 不。事实上，它们运行得非常好，只要您使用它们的非 Java SE-only 方法。

【问题讨论】：
-
Android 没有这些类，因此您无论如何都不能在您的 Android 应用中使用它们。
-
我假设您将其作为库包含在内，因此您需要将其附加到
-libraryjars，但我真的不明白您要在这里做什么。这些类不适用于 android。 -
都是图书馆。事实上，在我介绍 proguard 之前，它们（例如 pinyin4j-2.5.0.jar -> demo.Pinyin4jAppletDemo）可以完美运行。它们起作用的原因是，我只使用库中的方法，这不涉及仅限 Java SE 的方法。现在的问题是，ProGuard 似乎想要处理我所有的 lib jar。

@njzk2 有错误的类都是库。因此，我通过告诉 proguards 想，“嘿，这些是图书馆！”。事情会更好。事实上，它没有帮助。
