android 怎么实现只混淆自己的代码，而不混淆第3方jar包

Posted 2023-05-09

1. 新建一个工程会看到项目下边有这样proguard-project.txt一个文件，这个对混淆代码很重要，如果不小心删掉了，没关系，从其他地方拷贝一个过来
2. 最重要的就是在proguard-project.txt添加混淆的申明了：
a. 把所有的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 *;

3.以上工作完成，混淆工作就完成了一大半了，最后需要做的就是在project.properties文件中加上混淆文件申明了，如下
proguard.config=$sdk.dir/tools/proguard/proguard-android.txt:proguard-project.txt
4. OK， 最后一步，打签名包测试，如果有问题，仔细看下Log也许有得类不能混淆，那么你得加入到proguard-project.txt文件中
-------以上就是混淆代码的全过程了 参考技术A 在第三方的包中有些函数例如这样，

public sdkMethod(View view)



在混淆后，在配置文件中如果调用这个函数，是没有办法找到的。看下具体那个函数找，找到具体的类，设置下keep即可，如一般的广告jar包这么忽略;

-keep class com.google.ads.** *;
-keep class com.adwhirl.** *; 本回答被提问者和网友采纳

Android-android 怎么实现只混淆自己的代码，而不混淆第3方jar包

参考技术A 　　为了解决第三方包不被混淆，第三方包在混淆后，运行的时候会挂掉。我的错误是java.lang.ExceptionInInitializerError

[java] E/AndroidRuntime( 9608):
java.lang.ExceptionInInitializerError
E/AndroidRuntime( 9608): at
a.a.b.f.<init>(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.b.e.<init>(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.dg.b(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.dg.a(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.b.a(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.ad.a(Unknown Source)

　　………………………………………………………………………………中间部分省略
　　最终我通过 加LOG的调试方法定位到是由于第三方jar包被混淆后的原因导致的。

　　解决方法：
　　在proguard-android.txt文件最后加入了-keep class org.jsoup.**这样一句代码，就是保持这个类不被混淆

　　附上proguard-android.txt源文件
