Android 代码混淆一些知识

我们现在采用的都是android studio，只需要在proguard-rules.pro中添加混淆的申明：

a. 把所有你的jar包都申明进来，例如：  
 -libraryjars libs/apns\_1.0.6.jar  
 -libraryjars libs/armeabi/libBaiduMapSDK\_v2\_3\_1.so  
 -libraryjars libs/armeabi/liblocSDK4.so  
\-libraryjars libs/baidumapapi\_v2\_3\_1.jar  
\-libraryjars libs/core.jar  
\-libraryjars libs/gesture-imageview.jar  
\-libraryjars libs/gson-2.0.jar  
\-libraryjars libs/infogracesound.jar  
\-libraryjars libs/locSDK\_4.0.jar  
\-libraryjars libs/ormlite-[Android][]\-4.48.jar  
\-libraryjars libs/ormlite-core-4.48.jar  
\-libraryjars libs/universal-image-loader-1.9.0.jar

b. 将你不需要混淆的部分申明进来，因为有些类经过混淆会导致程序编译不通过，如下：

\-keep public class \* extends android.app.Fragment    
\-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.support.v4.\*\*  
\-keep public class com.android.vending.licensing.ILicensingService

\--以上都是API里边的类，最好都要避免混淆

有些很特殊的，例如百度地图，你需要添加以下申明：

\-keep class com.baidu.\*\* \{ \*; \}   
\-keep class vi.com.gdi.bgl.android.\*\*\{\*;\}

根据我的经验，一般model最好避免混淆（model无关紧要，不混淆也没多大关系）如：

\-keep class com.bank.pingan.model.\*\* \{ \*; \}  
下面在贴上关于Umeng分享统计的避免混淆的申明

\-dontwarn android.support.v4.\*\*    
\-dontwarn org.apache.commons[.NET][].\*\*   
\-dontwarn com.tencent.\*\*

\-keepclasseswithmembernames class \* \{  
    native <methods>;  
\}

\-keepclasseswithmembernames class \* \{  
    public <init>(android.content.Context, android.util.AttributeSet);  
\}

\-keepclasseswithmembernames class \* \{  
    public <init>(android.content.Context, android.util.AttributeSet, int);  
\}

\-keepclassmembers enum \* \{  
    public static \*\*\[\] values();  
    public static \*\* valueOf([Java][].lang.String);  
\}

\-keep class \* implements android.os.Parcelable \{  
  public static final android.os.Parcelable$Creator \*;  
\}

\-keepclasseswithmembers class \* \{  
    public <init>(android.content.Context);  
\}

\-dontshrink  
\-dontoptimize  
\-dontwarn com.google.android.maps.\*\*  
\-dontwarn android.webkit.WebView  
\-dontwarn com.umeng.\*\*  
\-dontwarn com.tencent.weibo.sdk.\*\*  
\-dontwarn com.facebook.\*\*

\-keep enum com.facebook.\*\*  
\-keepattributes Exceptions,InnerClasses,Signature  
\-keepattributes \*Annotation\*  
\-keepattributes SourceFile,LineNumberTable

\-keep public interface com.facebook.\*\*  
\-keep public interface com.tencent.\*\*  
\-keep public interface com.umeng.socialize.\*\*  
\-keep public interface com.umeng.socialize.sensor.\*\*  
\-keep public interface com.umeng.scrshot.\*\*

\-keep public class com.umeng.socialize.\* \{\*;\}  
\-keep public class javax.\*\*  
\-keep public class android.webkit.\*\*

\-keep class com.facebook.\*\*  
\-keep class com.umeng.scrshot.\*\*  
\-keep public class com.tencent.\*\* \{\*;\}  
\-keep class com.umeng.socialize.sensor.\*\*

\-keep class com.tencent.mm.sdk.openapi.WXMediaMessage \{\*;\}

\-keep class com.tencent.mm.sdk.openapi.\*\* implements com.tencent.mm.sdk.openapi.WXMediaMessage$IMediaObject \{\*;\}

\-keep class im.yixin.sdk.api.YXMessage \{\*;\}  
\-keep class im.yixin.sdk.api.\*\* implements im.yixin.sdk.api.YXMessage$YXMessageData\{\*;\}

\-keep public class \[your\_pkg\].R$\*\{  
    public static final int \*;  
\}

这些做完后要在build中打开混淆开关：

最后贴上proguard-project.txt的全部代码：（直接可以用于项目中）
