Android Code obfuscation notes

The obfuscation apk is hard to understand, such as the package name Class name in the anti-compilation code.

Use code obfuscation, enable the obfuscation, edit the relevant files, and then package the signature on it;

------------

In the 2.3 version, the project has this file proguard.cfg (no can be added manually)

Add a sentence: proguard.config=proguard.cfg

Contents of the Proguard.cfg file:

-optimizationpasses 5- Dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontpreverify-verbose-optimizations!code/ Simplification/arithmetic,!field/*,!class/merging/*-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 Androi D.content.broadcastreceiver-keep public class * extends Android.content.contentprovider-keep public class Com.android.vending.licensing.ilicensingservice-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 *;} 

-------------------------

In the version after 4.0, the files in the project are Project.Properties and Proguard-project.txt.

Open Project.Properties and uncomment the following line of code:

Proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

The default settings are not optimized, and you can use the following settings to add code optimization features:
#proguard. Config=${sdk.dir}/tools/proguard/proguard-android-optimize.txt:proguard-project.txt

-------------------------------------------------------

Some editing rules for proguard-project.txt files:

-libraryjars Libs/android-support-v4.jar

-libraryjars Libs loading third-party jar packages

-ignorewarnings Removing warnings from your code

-keep class com.xxx.xxx.**

-keep preserving non-confusing classes

Public methods of this class are reserved and not confused.
-keep class com.xx.xx.test{
public *;
}

Protecting the specified class files and members of a class

-keep class * Implements Android.os.Parcelable {

public static final Android.os.parcelable$creator *;
}

----------------------------------------------------

To package a signature with the Eclipse tool:

In Eclipse, select Project, right-click Menu--Android Tools

---> Export signed application Package ... With RSA digital signature

---> Export Unsigned application Package ... With no digital signature

Choose a way to follow the wizard, and the resulting apk is a confusing process.
