Intellij idea 和android studio 代码给混淆

一、指令说明
-optimizationpasses 5          # 指定代码的压缩级别

-dontusemixedcaseclassnames   # 是否使用大小写混合

-dontpreverify           # 混淆时是否做预校验

-verbose                # 混淆时是否记录日志

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*  # 混淆时所采用的算法

-keep public class * extends android.app.Activity      # 保持哪些类不被混淆

-keep public class * extends android.app.Application   # 保持哪些类不被混淆

-keep public class * extends android.app.Service       # 保持哪些类不被混淆

-keep public class * extends android.content.BroadcastReceiver  # 保持哪些类不被混淆

-keep public class * extends android.content.ContentProvider    # 保持哪些类不被混淆

-keep public class * extends android.app.backup.BackupAgentHelper # 保持哪些类不被混淆

-keep public class * extends android.preference.Preference        # 保持哪些类不被混淆

-keep public class com.android.vending.licensing.ILicensingService    # 保持哪些类不被混淆

-keepclasseswithmembernames class * {  # 保持 native 方法不被混淆

    native <methods>;

}

-keepclasseswithmembers class * {   # 保持自定义控件类不被混淆

    public <init>(android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembers class * {# 保持自定义控件类不被混淆

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

}

-keepclassmembers class * extends android.app.Activity { # 保持自定义控件类不被混淆

    public void *(android.view.View);

}

-keepclassmembers enum * {     # 保持枚举 enum 类不被混淆

    public static **[] values();

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

}

-keep class * implements android.os.Parcelable { # 保持 Parcelable 不被混淆

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

}

二、混淆实例

1、在proguard-project.txt里面配置混淆后;

2、在project.properties中添加proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

3.混淆实例参考

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-ignorewarnings
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-dontwarn android.support.**
-dontwarn com.handmark.**
-dontwarn android.webkit.WebView

-keepclassmembers class youmengyou.bean.** {
public <fields>;
private <fields>;
public <init>();
public <init>(org.json.JSONObject);
*;
}

#保持 native 方法不被混淆
-keepclasseswithmembernames class * {
native <methods>;
}

 #保持自定义控件类不被混淆
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
}

 #保持自定义控件类不被混淆
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}

 #保持自定义控件类不被混淆
-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}

#保持枚举类不被混淆
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
-keep public class * extends android.view.View {
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}
-keepclassmembers class **.R$* {
    public static <fields>;
    public static final int *;
}
-keepnames class * implements java.io.Serializable
-keepclassmembers class * implements java.io.Serializable {
   static final long serialVersionUID;
   private static final java.io.ObjectStreamField[] serialPersistentFields;
   !static !transient <fields>;
   private void writeObject(java.io.ObjectOutputStream);
   private void readObject(java.io.ObjectInputStream);
   java.lang.Object writeReplace();
   java.lang.Object readResolve();
}
-keepattributes Exceptions,InnerClasses,Signature
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.IntentService
-keep public class * extends android.app.Service
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * extends android.widget.LinearLayout
-keep public class * extends android.widget.FrameLayout
-keep public class * extends android.widget.CheckBox
-keep class android.** { *; }
-keep public class javax.**
-keep class org.** { *; }
-keep class android.support.v4.** {*;}
-keep class android.support.v4.app.** { *; }
-keep class android.support.v4.view.** { *; }
-keep public class * extends android.support.v4.**
-keep public class android.webkit.**

#加解密
#-keep public class com.jfw.utils.ThreeDES

-keep interface android.support.v4.app.** { *; }
#下拉刷新
-keep class com.handmark.** { *; }

三、最后一步，打包、签名

以前总以为Intellij idea 和android studio 在proguard-project.txt里面设置以后，在编译的时候就直接把代码给混淆了，后面自己反编译才发现，什么都混淆，原来还有个操作没做，需要在Generate Signed APK （签名）的时候勾选上Run ProGuard 才行。
