Android如何保持指定类不被混淆?

android-android怎么实现只混淆自己的代码，而不混淆第3方jar包~

当项目中有第3方jar包时，怎么实现混淆打包，而不对第3方包混淆
在项目中有第3方包时打包出错日志：

我的proguard.cfg 文件时这样的

-optimizationpasses 5

-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclasses

-verbose

-ignorewarnings

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-libraryjars libs/bcprov-jdk15on-147.jar

-keep public class * extends android.content.ContentProvider

-keep public class * extends android.app.backup.BackupAgentHelper

}

-keepclasseswithmembers class * {

public (android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembers class * {

public (android.content.Context, android.util.AttributeSet, int);

}

-keepclassmembers class * extends android.app.Activity {

public void *(android.view.View);

}

-keepclassmembers enum * {

public static **[] values();

public static ** valueOf(java.lang.String);

}

-keep class * implements android.os.Parcelable {

public static final android.os.Parcelable$Creator *;

}
已经尝试的方案：方案一： 加入-ignorewarnings 可以正常打包了。 能过滤掉警告信息。但是治标不治本，打好的包，在实际运行中用到过的第3方包类库时，均报空指针。方案二：不使用-ignorewarnings 添加-dontwarn java.awt.datatransfer.Transferable.** 警告信息并没有减少，打包会失败。

　　为了解决第三方包不被混淆，第三方包在混淆后，运行的时候会挂掉。我的错误是java.lang.ExceptionInInitializerError


[java] E/AndroidRuntime( 9608):

　　最终我通过 加LOG的调试方法定位到是由于第三方jar包被混淆后的原因导致的。

　　解决方法：
　　在proguard-android.txt文件最后加入了-keep class org.jsoup.**这样一句代码，就是保持这个类不被混淆

　　附上proguard-android.txt源文件

包名 package com.example.test
类名 public class WebAppInterface{}
加上完整的包名才行。
-keep class com.example.test.WebAppInterface {*;}

原航苏可： 加上完整的包名才行.-keep class com.example.test.WebAppInterface {*;}

峄城区13411609873： android 怎么实现只混淆自己的代码,而不混淆第3方 - ？
原航苏可： 混淆打包流程: 1在proguard-projecttxt文件中添加不需要混淆的类和第三方的jar包 这个是保持自己包中不需要混淆的类,如果有些类调用了jni也不需要混淆,不然会出错.还有如果项目中有其他项目作为library引入,那这些项目的一些类也不能混淆android 怎么实现只混淆自己的代码,而不混淆第3方

峄城区13411609873： android 如何取消第三方包混淆？
原航苏可： keep 住第三方包对应的包名或或者指定类.如: -keep public class android.app.**

峄城区13411609873： android中为什么要指定第三方包的中内容不混淆呢/ - ？
原航苏可： 其实第三方jar包是不能混淆,这里指定第三方jar包不混淆的意思是,在你的项目中的调用到第三方jar包的语句不被混淆,你想想,如果jar包是com.umeng,你调用的地方被混淆成了a.b,这样你生成的apk里面不是找不到a.b了么,肯定会报错撒

峄城区13411609873： Android 开发怎样做代码加密或混淆 - ？
原航苏可： Proguard对一般用途来说足够了,但是也需要注意一些程序风格,增强proguard的效果:1. 特定类的public函数不做实际的事情,只做简单处理后调用private函数.proguard对会对一些特定类的public函数不做混淆,以便被AndroidManifest.xml和各种layout引用.2. 会被AndroidMinifest.xml和layout引用的类放在浅层的包中,需要隐藏的类放在较深处,以便proguard混淆包名带来好处.如果一个包中有需要不混淆的内容,则整个包名都不会被混淆.3. 将函数根据功能分细切短也会有些益处.如果隐藏代码的要求比较高,还是用native好了.

峄城区13411609873： 如何禁止android默认编译选项 - ？
原航苏可： 为Android应用开发者,不得不面对一个尴尬的局面,就是自己辛辛苦苦开发的应用可以被别人很轻易的就反编译出来.Google似乎也发现了这个问题,从SDK2.3开始我们可以看到在android-sdk-windows\tools\下面多了一个proguard文件夹 ...

峄城区13411609873： 关于Android studio 怎么使用代码混淆的问题 - ？
原航苏可： 1,在build.grandle添加,其中规则写在proguard-rules.pro中,也可以自定义一个文件,将其代替,比如eclipse常用的 proguard-project.txt buildTypes { release { signingConfig signingConfigs.release minifyEnabled true proguardFiles ...

峄城区13411609873： android 加入library如何混淆 - ？
原航苏可： android工程会看到项目有 project.properties 这个文件就是用来开启项目是否混淆 proguard-project.txt 这个文件就是记录了代码混淆的属性 要开启混淆,只需要将project.properties 文件中的# proguard.config=${sdk.dir}/tools/proguard/proguard-...

峄城区13411609873： android 代码混淆怎么没效果 - ？
原航苏可： 如果你没用到第三方的library或者jar包,那么只要在工程目录下project.properties里面,把#proguard.config=xxxxxx前面的#去掉就好了.如果有第三方的jar包,那么把需要的配置加到proguard-project.txt里面就好.

峄城区13411609873： android代码混淆以及怎么判断一个apk代码是否被混淆过 - ？
原航苏可： 反编译一下,没有混淆过的反编译过来和你正常的代码一样 混淆过的反编译过来的,代码结构和原来一样,但是里面的方法名可能都被改成 public void a()这样的了
