Android 代码混淆及第三方jar包不被混淆

为了保护代码被反编译,android引入了混淆代码的概念
在文件中加入proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt这个是系统的
也可以用自己的混淆文件(这样就可以配置一些自己的东西),去sdk.dir}/tools/proguard/ 下复制proguard-android.txt文件到本地工程中
然后设置成proguard.config=proguard-android.txt
最终我通过 加LOG的调试方法定位到是由于第三方jar包被混淆后的原因导致的。
附上proguard-android.txt源文件
1.设置混淆
在工程下找到project.properties文件在文件中加入proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt这个是系统的
也可以用自己的混淆文件(这样就可以配置一些自己的东西),去sdk.dir}/tools/proguard/ 下复制proguard-android.txt文件到本地工程中
然后设置成proguard.config=proguard-android.txt
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt proguard.config=proguard-android.txt # Project target. target=android-17
2.配置自己的混淆文件proguard-android.txt
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.ExceptionInInitializerErrorE/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) E/AndroidRuntime( 9608): at a.a.a.a(Unknown Source) E/AndroidRuntime( 9608): at com.petsea.c.a(Unknown Source) E/AndroidRuntime( 9608): at com.petsea.c.a(Unknown Source) E/AndroidRuntime( 9608): at com.petsea.h.a(Unknown Source) E/AndroidRuntime( 9608): at com.petsea.h.onPostExecute(Unknown Source) E/AndroidRuntime( 9608): at android.os.AsyncTask.finish(AsyncTask.java:631) E/AndroidRuntime( 9608): at android.os.AsyncTask.access$600(AsyncTask.java:177) E/AndroidRuntime( 9608): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:644) E/AndroidRuntime( 9608): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 9608): at android.os.Looper.loop(Looper.java:137) E/AndroidRuntime( 9608): at android.app.ActivityThread.main(ActivityThread.java:5041) E/AndroidRuntime( 9608): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 9608): at java.lang.reflect.Method.invoke(Method.java:511) E/AndroidRuntime( 9608): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) E/AndroidRuntime( 9608): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) E/AndroidRuntime( 9608): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 9608): Caused by: java.lang.ExceptionInInitializerError E/AndroidRuntime( 9608): at a.a.b.l.<clinit>(Unknown Source) E/AndroidRuntime( 9608): ... 22 more
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。
3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
# This is a configuration file for ProGuard. # http://proguard.sourceforge.net/index.html#manual/usage.html -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -verbose # Optimization is turned off by default. Dex does not like code run # through the ProGuard optimize and preverify steps (and performs some # of these optimizations on its own). -dontoptimize -dontpreverify # Note that if you want to enable optimization, you cannot just # include optimization flags in your own project configuration file; # instead you will need to point to the # "proguard-android-optimize.txt" file instead of this one from your # project.properties file. -keepattributes *Annotation* -keep public class com.google.vending.licensing.ILicensingService -keep public class com.android.vending.licensing.ILicensingService # For native methods, see http://proguard.sourceforge.net/manual/examples.html#native -keepclasseswithmembernames class * { native <methods>; } # keep setters in Views so that animations can still work. # see http://proguard.sourceforge.net/manual/examples.html#beans -keepclassmembers public class * extends android.view.View { void set*(***); *** get*(); } # We want to keep methods in Activity that could be used in the XML attribute onClick -keepclassmembers class * extends android.app.Activity { public void *(android.view.View); } # For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); } -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; } -keepclassmembers class **.R$* { public static <fields>; } # The support library contains references to newer platform versions. # Don't warn about those in case this app is linking against an older # platform version. We know about them, and they are safe. -dontwarn android.support.** -keep class org.jsoup.**
