android - 从 Android proguard 中排除 Java SE 库

Question

在 Android 中，我有以下设置的 proguard。

-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）

我如何将它们排除在 proguard 之外？请注意，我pinyin4j-2.5.0.jar在-libraryjars. 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。

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。没有。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。

如果您确定未使用这些 Java SE 类，则确实可以忽略警告（正如您在自己的答案中发现的那样）。一种更简单的指定方法：

-dontwarn java.beans.**
-dontwarn java.awt.**
-dontwarn javax.swing.**

请参阅ProGuard 手册 > 故障排除 > 警告：找不到引用的类

类似的问题总是有相同的答案：

保留 java 运行时的示例 (rt.jar)

<libraryjar file="${java.home}/lib/rt.jar" />

看来你的线

-libraryjars libs/google/jsr305-1.3.9.jar;libs/pinyin4j/pinyin4j-2.5.0.jar

不完整。更新但由于 android 上不存在所需的类，因此您必须忽略这些警告。但是通常不要忽略混淆警告，我们有一个严重的错误（在文件中使用 obfuscation.map），因为我们忽略了所有警告。

我只是通过以下方式避免错误

-dontwarn sun.misc.Unsafe
-dontwarn com.google.common.collect.MinMaxPriorityQueue
-dontwarn javax.swing.**
-dontwarn java.awt.**
-dontwarn org.jasypt.encryption.pbe.**
-dontwarn java.beans.**
-dontwarn org.joda.time.**
-dontwarn com.google.android.gms.**
-dontwarn org.w3c.dom.bootstrap.**
-dontwarn com.ibm.icu.text.**
-dontwarn demo.**

这是完整的proguard配置

-optimizationpasses 1
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

#-dontobfuscate

-dontwarn org.joda.time.**

}

它还不能完全开箱即用，因为我仍然在“proguard 生成后”APK 中遇到崩溃。

我很难找出它崩溃的原因，因为代码很模糊。

如果我具体dontobfuscate，我会在生成过程中遇到另一组问题。弹出一条消息“转换为 Dalvik 格式失败，错误 1”，但没有其他信息。但是，这是另一组不同的问题。
