Obfuscation packaging specification for Android applications

Obfuscation Packaging specification for Android applications

1. Add the following proguard.config=proguard.cfg to the project file project.properties as follows:

Target=android-8

Proguard.config=proguard.cfg

This configuration is used by Eclipse to generate the proguard.cfg file in the project catalog , but this can only confuse projects that do not contain third-party packages.

third party Package cause the packaging to be unsuccessful, Or packaging success can not run the situation

2. Engineering confusion with third-party libraries, first to look at the official documentation of the reference library, usually gives a confusing scenario, because sometimes a third-party library might not have only one jar package, and the third-party library itself may also use other jars Bag, it's a waste of time to find a separate mix.

3. Common third-party library obfuscation process:

1. First add -dontwarn// without output warning , increase the success rate of confusion

2. remove the warning from the package name of the corresponding third-party library by using the same method

-dontwarn com.slidingmenu.lib.app.**

-dontwarn com.actionbarsherlock.app.**

-dontwarn android.support.v4.**

-dontwarn com.slidingmenu.lib.**

-dontwarn cn.sharesdk.**

3. specify the path of the Lib package in the project,,,-libraryjars followed by other class packages to compile in.jar , If there are multiple, With a multi-row

-libraryjars Libs/gson-2.2.2.jar

4. after introduction, specify the entry class to which the project is used,-keep followed by the entry class for the project

-keep class universal-image-loader-1.8.4-with-sources.** {*;}

-keep interface universal-image-loader-1.8.4-with-sources.** {*;}

-keep class locksdk_3.3.** {*;}

-keep interface locksdk_3.3.** {*;}

-keep class mobileprobe.jar.** {*;}

-keep interface mobileprobe.jar.** {*;}

-keep class Android.net.http.SslError

-keep class android.webkit.**{*;}

-keep class cn.sharesdk.**{*;}

-keep class com.sina.**{*;}

Keep is telling Proguard not to confuse the class inside this bag.

5. Some special packages need attention

If you add a android.support bag, then add

-libraryjars Libs/android-support-v4.jar

-dontwarn android.support.v4.**

-keep class android.support.v4.** {;}

If you add a gson bag, then add

-libraryjars Libs/gson-2.2.2.jar

-keep class Sun.misc.Unsafe {*;}

-keep class com.google.gson.stream.* {;}

-keep class Com.google.gson.examples.android.model.* {;}

-keep class Com.google.gson.* {*;}

If the project contains entities referencing interfaces , then add

-keep public class * Implements java.io.serializable{

public protected Private *;

}

IfEntity with set value injection in ProjectWords,May be in the packaging run without error, For example, NULL pointer exception, or reflection when the error is not cannot get or set

-keep public class MyPackage. Mybean {public void Setmyproperty (int.); public int getmyproperty ();}

4. Finally, let's take a look at the process of confusion

-libraryjars Libs/android-support-v4.jar

-dontwarn android.support.v4.**

-keep class android.support.v4.** {;}

Explain:

-libraryjarsindicateLibThe path of the package in the project，and-dontwarn android.support.v4.**and the-keep class android.support.v4.** {;}，These two parameters are used To keep classes in third-party libraries-dontwarnand the-keepto use together means to keep android.support.v4.**  { ; }, The presence of an acceptable warning affects the operation of the program.

Note: confusing the basic process, that is, different third-party libraries are similar, you can use this method to deal with!!!
