Android混淆打包
在Android应用程序也可以使用 ProGuard来进行混洗打包,大大的优化Apk包的大小。但是 注意 ProGuard 对文件路径的名名很有讲究,不 支持括号 ,也不 支持空格 。 在混淆过后,可以在工程目录的 proguard中的 mapping.txt 看到混淆后的类名,方法名,变量名和 混淆前的类名,方法名,变量名。
在使用Eclipse或 Ant 打包应用程序时,都是使用Android工程目录的project.properties 文件来指定配置。关于Android中如何使用ant打包请参考《Android中使用Ant编译打包 》
在使用Eclipse新建一个工程,都会在工程目录下生产配置 project.properties和proguard-project.tx 。
# To enable ProGuard to
shrink and obfuscate your code, uncomment this (available
properties: sdk.dir, user.home):
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
target=android-10
project.properties 用于配置Android工程的一些属性,#号的话表示当前行是注释,这里的 proguard.config 就用于指定 ProGuard的 混淆配置文件,并对使用 release方式打包应用程序时开启 代码混淆 功能。对于是否是 使用release方式打包,和AndroidManifest.xml 中application的android:debuggable属性有很多关系。如果该值为 android:debuggable=" true " ,那么最终就是 debug方式打包。最明智的方式就是在 AndroidManifest.xml并不显示的指定它,而是是打包工具在打包时来决定它最终的值。 对于ant就是 ant release 或 ant debug。 而对于直接在Eclipse中使用run 或 debgu 来打包的话就是debug,使用export的话就是 release.
proguard . config = $ { sdk . dir }/ tools / proguard / proguard - android . txt : proguard- project . txt
这里的话指定了混淆的基本配置文件
proguard-android.txt ,和
混淆的个性化配置文件 proguard-project.txt。这里 proguard-project.txt文件用于对前面的 基本的混淆配置文件
proguard-android.txt 的配置进行override和添加。
混淆的基本配置文件
proguard-android.txt 如下:
文件1
# This is a configuration file for
ProGuard. #
http://proguard.sourceforge.net/index.html#manual/usage.html -dontusemixedcaseclassnames - dontskipnonpubliclibraryclasses - verbose #
Optimization is turned off by default. Dex does not like code
run #
through the ProGuard optimize and preverify steps (and performs
some #
of these optimizations on its
own). - dontoptimize - dontpreverify #
Note that if you want to enable optimization, you cannot
just #
include optimization flags in your own project configuration
file; # instead you will need to point to
the #
"proguard-android-optimize.txt" file instead of this one from
your #
project.properties file. -keepattributes * Annotation * - keep public class com . google . vending . licensing .ILicensingService - keep public class com . android . vending . licensing .ILicensingService #
For native methods, see
http://proguard.sourceforge.net/manual/examples.html#native -keepclasseswithmembernames class * { native ; } #
keep setters in Views so that animations can still
work. # see
http://proguard.sourceforge.net/manual/examples.html#beans - keepclassmemberspublic class * extends android . view . View { void set *(***); *** get *(); } #
We want to keep methods in Activity that could be used in the XML
attribute onClick -keepclassmembers class * extends android . app . Activity { public void *( android .view . View ); } #
For enumeration classes, see
http://proguard.sourceforge.net/manual/examples.html#enumerations -keepclassmembers enum * { public static **[] values (); public static ** valueOf ( java. lang . String ); } - keep class * implements android . os . Parcelable { public staticfinal android . os . Parcelable$Creator *; } - keepclassmembers class **. R$ * {public static ; } #
The support library contains references to newer platform
versions. # Don't warn about those in case this app
is linking against an older # platform version. We know about them,
and they are safe. - dontwarn
android .support .**
以下则个是我们项目 混淆的个性化配置文件 proguard-project.txt
# To enable ProGuard in your project, edit
project.properties # to define the proguard.config property
as described in that file. # # Add project specific ProGuard rules
here. # By default, the flags in this file are
appended to flags specified # in
${sdk.dir}/tools/proguard/proguard-android.txt #
You can edit the include path and order by changing the
ProGuard # include property in
project.properties. # # For more details,
see #
http://developer.android.com/guide/developing/tools/proguard.html #
Add any project specific keep options
here: # If your project uses WebView with JS,
uncomment the following # and specify the fully qualified class
name to the JavaScript
interface #
class: #-keepclassmembers class
fqcn.of.javascript.interface.for.webview
{ #
public *; #} - dontwarn
