Android mould 生成jar包并添加混淆

1、首先确定自己mould是用的那个版本的gradle。

2、根据mould使用的gradle配置环境变量。   (如果不配置环境变量，可能找不大道makejar功能入口)

3、环境变量配置成功后cmd  输入  gradle -v 查看是否配置完成。

  找到自己的gradle目录，一般如下：C:\Users\admin\.gradle\wrapper\dists

不过配置的环境不是这里，而是  C:\Users\admin\.gradle\wrapper\dists\gradle-5.4.1-all\3221gyojl5jsh0helicew7rwx\gradle-5.4.1

找到所在目录后，复制一下路径，然后打开电脑找到环境变量配置然后点击新建

填入一下信息

然后点击确定。

找到系统变量的path双击

然后输入刚才的名称即可

4、增加代码混淆  步骤：

先在moudle的build.gradle中加入如下代码   此代码跟  android { } 同一个级别

def SDK_BASENAME = "testjar";//jar包名称
def SDK_VERSION = "_v1.0.0";//版本好
def sdkDestinationPath = "build/outputs/jar/";//生成jar包路径
def zipFile = file('build/intermediates/packaged-classes/release/classes.jar')
task deleteBuild(type: Delete) {
    delete sdkDestinationPath + SDK_BASENAME + SDK_VERSION + ".jar"
}
task makeJar(type: Jar) {
    from zipTree(zipFile)
    from fileTree(dir: 'src/main', includes: ['assets/**']) // 打包assets目录下的所有文件

    baseName = SDK_BASENAME + SDK_VERSION
    destinationDir = file(sdkDestinationPath)
}
makeJar.dependsOn(deleteBuild, build)

另外启用混淆

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

最后是在混淆文件中添加混淆规则： 这是我在网上参照别人的，感觉还行。

# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# 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 *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile

###########################以下是AndroidStudio自带的混淆配置协议###############################

# 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.
#使用注解需要添加
-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
#指定不混淆所有的JNI方法
-keepclasseswithmembernames class * {

}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
#所有View的子类及其子类的get、set方法都不进行混淆
-keepclassmembers public class * extends android.view.View {
   void set*(***);

}

# We want to keep methods in Activity that could be used in the XML attribute onClick
# 不混淆Activity中参数类型为View的所有方法
-keepclassmembers class * extends android.app.Activity {

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
# 不混淆Enum类型的指定方法
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

# 不混淆Parcelable和它的子类，还有Creator成员变量
-keepclassmembers class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator CREATOR;
}

# 不混淆R类里及其所有内部static类中的所有static变量字段
-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.
# 不提示兼容库的错误警告
-dontwarn android.support.**

# Understand the @Keep support annotation.
-keep class android.support.annotation.Keep

-keep @android.support.annotation.Keep class * {*;}

-keepclasseswithmembers class * {

#-libraryjars "C:\Program Files\Java\jre1.8.0_151\lib\rt.jar"
#-libraryjars "C:\Users\admin\AppData\Local\Android\sdk\platforms\android-26\android.jar"
# 注意：以上两个路径需要将以上路径是自己jar包的位置，需要根据自己情况进行修改，如果报重复配置的错误，注释掉即可

#代码迭代优化的次数，默认5
#-optimizationpasses 5
#混淆时不会产生形形色色的类名
-dontusemixedcaseclassnames


#忽略警告
-ignorewarnings
#以下是不需要混淆的文件
 -keep class com.xhs.testjar.ToastUtil{

 }

 

 

5、添加完混淆后就是生成jar包，点击android studio 中右边的  gradle 弹出列表，找到自己的moudle 名字，然后点击Tasks-》other 最后双击里面的makeJar  即可生成jar包，也有arr文件。   arr文件在outputs -》arr中，
