前言
之前一直打包的sdk都是给内部项目使用的,没有提供给别的客户使用过,所以一直以来都是简单的功能打包,也不混淆,等最后的项目再写混淆方法。
最近要求提供sdk给客户但又要混淆业务逻辑,只好摸索一下,百度和谷歌都没有找到很好的教程。只能根据用过的第三方sdk的经验写一下,以下记录一下自己的想法。不能保证是优秀的代码。毕竟赶鸭子上架,有相关的经验的大佬,希望也能提点建议。
新建model
由于我直接打包aar就好了,所以就不配置jar包的设置了。
新建接口
新建文件 ITestUtil
public interface ITestUtil {
/**
* 打印
* @param msg
*/
void doLog(String msg);
}
新建业务
新建文件 TestUtil
public class TestUtil implements ITestUtil {
@Override
public void doLog(String msg) {
Log.e("TestUtil", "打印:" + msg);
}
}
混淆
基本混淆代码
直接放进你的混淆文件即可 proguard-rules.pro
#表示混淆时不使用大小写混合类名
-dontusemixedcaseclassnames
#表示不跳过library中的非public的类
-dontskipnonpubliclibraryclasses
#打印混淆的详细信息
-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
##表示不进行校验,这个校验作用 在java平台上的
-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 <methods>;
}
# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public 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);
}
-keepclassmembers class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator CREATOR;
}
-keepclassmembers class **.R$* {
public static <fields>;
}
# 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.**
# Understand the @Keep support annotation.
-keep class android.support.annotation.Keep
-keep @android.support.annotation.Keep class * {*;}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <methods>;
}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <fields>;
}
-keepclasseswithmembers class * {
@android.support.annotation.Keep <init>(...);
}
#忽略警告
-ignorewarnings
#保证是独立的jar,没有任何项目引用,如果不写就会认为我们所有的代码是无用的,从而把所有的代码压缩掉,导出一个空的jar
-dontshrink
#保护泛型
-keepattributes Signature
自定义相关混淆
添加自己的相关混淆配置
# 不混淆某个类(使用者可以看到全部信息)
-keep class com.rdwl.testlib.ITestUtil {*;}
# 不混淆某个类(使用者可以看到类名)
-keep class com.rdwl.testlib.TestUtil
# 不混淆某个类中以 public 开始的方法(使用者可以看到该方法)
#-keepclassmembers class com.rdwl.testlib.TestUtil {
# public *;
#}
开启混淆
打开 model 的 build.gradle 文件
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
混淆正式打包
点击右侧边栏的 Gradle,在窗口中找到你的 model,选择 Tasks -> build -> build
,如果你打开 Gradle 窗口显示 Nothing to show,你可以看下我的这篇文章:Android studio右侧Gradle窗口显示 nothing to show
等待打包完成。你就能在model的build文件夹找到打包好的aar
