Android Obfuscation code details and examples

Android Obfuscation Code details and examples

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 ;

}

-keepclasseswithmembernames class * {

Public (Android.content.Context, Android.util.AttributeSet);

}

-keepclasseswithmembernames class * {

Public (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 (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:
