从Android proguard中排除Java SE库

标签： android proguard

在Android中，我使用以下设置进行预测。

-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>;
}

我的一些库直接从Java SE导入（例如包含JApplet）

我怎样才能将他们从proguard中排除？请注意，pinyin4j-2.5.0.jar中有-libraryjars个库。我认为这是告诉proguard的方式，＆＃34;嘿，这是一个图书馆。不要做任何事情，好吗？＆＃34;但是，似乎proguard仍在尝试处理pinyin4j-2.5.0.jar

我收到以下错误。

有些人可能会评论说，对于包含Java SE的库jar，只有方法（如Applet，Swing，...）不能在Android中使用。的不。实际上，只要您使用非Java SE-only方法，它们就可以完美运行。

3 个答案:

答案 0 :(得分：6)

如果您确定未使用这些Java SE类，您确实可以忽略警告（正如您在自己的答案中找到的那样）。一种更简单的方法来指定：

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

请参阅ProGuard manual > Troubleshooting > Warning: can't find referenced class

类似的问题总是有相同的答案：

答案 1 :(得分：1)

保持java运行时（rt.jar）

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

看来你的行

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

不完整。 的更新 但由于android上不存在所需的类，因此必须忽略这些警告。 但是一般不要忽略混淆警告，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。

答案 2 :(得分：0)

我只是通过

来避免错误 
-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/*

# I use Google Guava in my app

-libraryjars libs/google/jsr305-1.3.9.jar

-keepclasseswithmembers class com.google.common.base.internal.Finalizer{
    <methods>;
}

它完全没有开箱即用，因为我仍然在“在proguard生成后”APK中遇到崩溃。

我很难找到崩溃的原因，因为代码是混淆的。

如果我具体dontobfuscate，我会在生成过程中遇到另一组问题。弹出“转换为Dalvik格式失败，错误1”消息，但没有附加信息。但是，这是另一套不同的问题。
