Android Obfuscation Code and example _android

To prevent the results of their work from being stolen, confusing code can effectively prevent being decompile, the following is a summary of the following confusing code steps:

1. You may have noticed that a new project would see a file like this on the bottom of the project, which is important for confusing code, and if you accidentally delete it, it's okay, copy one from somewhere else proguard-project.txt.

2. The most important thing is to add a confusing statement to the Proguard-project.txt:

A. Declare all your jar packs, for example:

-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. Make a statement that you don't need to be confused because some classes are confusing and cause the program to compile and not pass, as follows:

-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

--These are the classes in the API, and it's best to avoid confusion.

Some very special, such as Baidu Map, you need to add the following statement:

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

According to my experience, the general model is best to avoid confusion (model does not matter, not confused and not much relationship) such as:

-keep class com.bank.pingan.model.** {*;}

Here's a statement about avoiding confusion about Umeng sharing statistics.

-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. The above work completes, confuses the work to complete the half, finally needs to do is in the Project.Properties file adds your confusing document to affirm, as follows:
Proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

4. OK, the last step, the signature package test, if there is a problem, carefully look at the log may be a class can not be confused, then you have to add to the Proguard-project.txt file

-------above is the whole process of confusing code.

Finally, paste all the Proguard-project.txt code:

# to enable Proguard in your project, edit Project.Properties # to define the Proguard.config property as described in T 
Hat file. 
# ADD Project specific Proguard rules here. 
# By default, the flags in this file are appended to flags specified # in ${sdk.dir}/tools/proguard/proguard-android.txt 
# You can edit the ' include path and order by changing the ' Proguard # include in Project.Properties. # for more details, and # http://developer.android.com/guide/developing/tools/proguard.html # ADD any project spec Ific Keep options here: # If your project uses WebView with JS, uncomment the following # and specify the fully Qualif

1. Project-dependent JAR declaration:

The following is an instance of sending a message

-libraryjars.. /klowerbase/libs/mail-activation.jar
-libraryjars.. /klowerbase/libs/mail-additionnal.jar
-libraryjars.. /klowerbase/libs/mail.jar

2. Resolve mail sent by the times of abnormal

 -keep class javax.mail.**{*;} 
 -keep class com.sun.mail.**{*;} 
-keep class javax.activation.**{*;} 
-keep class org.apache.harmony.**{*;} 

#解决: Can ' t find referenced class Java.beans.Beans 
-dontwarn org.apache.commons.collections.BeanMap 
-dontwarn java.beans.** 
#解决: Can ' t find referenced class JAVAX.SECURITY.SASL.SASL 

Through this article I hope to help the Android development application using confusing code friends, thank you for your support for this site!
