android的Proguard混淆

这几天在混淆代码过程中遇到好几个坑，所幸堵了《app研发录》这本书，帮了我的大忙。

现记录先后遇到的几个坑：

1. butterknife，在混淆时注意是6.0还是7.0，混淆方式不一样；

2. 实体bean不要混淆，这会影响到JSON的使用；

3. 内部类尽量独立出来，无法独立单独的class，要标记不要混淆；

4. 友盟sdk，打包时一直提醒几千个警告，目前不知怎么解决

其他方面，下面这篇博客也有很大帮助：

Android Proguard原理

第三方库的混淆可以参考：

各框架库混淆

另外，记录下我的proguard内容，很多部分是拜《App研发录》的帮助，有兴趣的可以看看这本书（非广告）：

#---------------------------------------------基本设置-----------------------------------------------
-optimizationpasses 5   #代码混淆压缩比，0-7之间，默认5
-dontusemixedcaseclassnames   #混淆时不使用大小写混合，混淆后类名小写
-dontskipnonpubliclibraryclasses   #指定不去忽略非公共的类
-dontskipnonpubliclibraryclassmembers   #指定不去忽略非公共的类的成员
-dontpreverify   #不做预校验，android一般不用，加快速度
-verbose   #生成映射文件
-printmapping proguardMapping.txt   #映射文件名称
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*   #混淆算法，一般不变
-keepattributes *Annotation*   #Annotation不混淆，对于JSON实体映射重要，例如FastJson/Gson
-keepattributes Signature   #避免混淆泛型，对于JSON实体映射重要
-keepattributes SourceFile,LineNumberTable   #抛出异常时保留代码行号
#保留所有本地native方法
-keepclasseswithmembernames class * {
native <methods>;
}
#保留继承自Activity、Application类的子类，可能被外部调用
-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 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 * extends android.view.View
-keep public class com.android.vending.licensing.ILicensingService
#-------------------------------------------v4/v7/Fragment------------------------------------------
-dontwarn android.support.v7.**
-keep class android.support.v7.**{*;}
-keep interface android.support.v7.app.**{*;}
-keep public class * extends android.support.v7.**
-keep public class * extends android.app.Fragment
#保留Activity中方法参数是view的方法，使onClick不受影响
-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}
#枚举类不被混淆
-keepclassmembers enum * {
public static **[] values();
public static ** valueOf(java.lang.String);
}
#自定义控件（继承自View）不被混淆
-keep public class * extends android.view.View{
*** get*();
void set*(***);
public <init>(android.content.Context);
public <init>(android.content.Context, android.util.AttributeSet);
public <init>(android.content.Context, android.util.AttributeSet, int);
}
#Parcelable序列化类不混淆
-keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
#Serializable序列化类不混淆
-keepclassmembers class * implements java.io.Serializable {
static final long serialVersionUID;
private static final java.io.ObjextStreamField[] serialPersistentFields;
private void writeObject(java.io.ObjectOutputStream);
private void readObject(java.io.ObjectInputStream);
java.lang.Object writeReplace();
java.lang.Object readResolve();
}
#R类及资源不混淆
-keep class **.R$*{
*;
}
#带有回调函数onXXXEvent的不混淆
-keepclassmembers class * {
void *(**On*Event);
}
#保留实体类和成员不被混淆
-keep public class com.qtest.journal.bean.**{
#    public void set*(***);
#    public *** get*();
#    public *** is*();
*;
}
#WebView处理
-keepclassmembers class * extends android.webkit.webViewClient {
public void *(android.webkit.WebView, java.lang.String, android.graphics.Bitmap);
public boolean *(android.webkit.WebView, java.lang.String);
}
-keepclassmembers class * extends android.webkit.webViewClient {
public void *(android.webkit.webView, java.lang.String);
}
#内嵌类
#Javascript处理
#反射处理
#release包去除敏感verbose/debug的log日志信息
-dontobfuscate   #prevent from changing class name and method name etc...
-assumenosideeffects class android.util.Log{
public static int d(...);
public static int v(...);
}
