Android(安卓)Studio 打Jar包和混淆的Jar包

一打不混淆的包

1 新建 Android Library工程作为打 jar包要用的工程

2 在 library的 build.gradle文件中加入如下代码：

task makeJar(type: Jar, dependsOn: ['build']) {    delete 'build/libs/testSDK.jar'    baseName 'testSDK'    from('build/intermediates/classes/release')    exclude "**/R.class"    exclude { it.name.startsWith('R$'); }}

3 生成jar包
找到Gradle目录下的，刚刚创建的Android Library名称目录下的Tasks，打开other目录,再找到makeJar,点击便开始打包jar

生成的jar包位置如下:

二打包混淆的 jar

1 proguard-rules.pro 中加入以下不需要混淆的说明

-target 1.6-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*-optimizationpasses 5-dontusemixedcaseclassnames-keepattributes Exceptions,InnerClasses,Signature,Deprecated,SourceFile,LineNumberTable,LocalVariable*Table,*Annotation*,Synthetic,EnclosingMethod-keepparameternames-verbose-ignorewarnings-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 no.nordicsemi.android.dfu.DfuBaseService-keep public class * extends android.content.BroadcastReceiver-keep public class * extends android.content.ContentProvider-keep public class * extends android.app.backup.BackupAgentHelper-keep public class * extends android.preference.Preference-keep public class com.android.vending.licensing.ILicensingService-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);}-keep class * extends android.os.Parcelable {    public static final android.os.Parcelable$Creator *;}# Keep - Library. Keep all public and protected classes, fields, and methods.#-keep public class * {#    public ;#    public ;#}

2 在 library的 build.gradle文件中继续加入如下代码：

task makeProguardJar(type: proguard.gradle.ProGuardTask, dependsOn: ['makeJar']) {    // 未混淆的jar路径    injars 'build/libs/testSDK.jar'    // 混淆后的jar输出路径    outjars 'build/libs/proGuard_testSDK.jar'    // 混淆协议    configuration 'proguard-rules.pro'}

表示生成的混淆jar包在 —> build/libs/proGuard_testSDK.jar

3 找到Gradle目录下的，刚刚创建的Android Library名称目录下的 Tasks，打开 other目录,再找到 makeProguardJar, 点击便开始打混淆的 jar包，如下图：

4 生成jar包如图：
