2-step code obfuscation and 2-step code obfuscation

2-step code obfuscation and 2-step code obfuscation

[Step 1 ]:

Modify build. gradle under module
BuildTypes {
Release {
// Whether to confuse
MinifyEnabled true
// Location of the obfuscated File
// Proguard is a free tool for compressing, optimizing, and confusing Java bytecode files
ProguardFiles getDefaultProguardFile('proguard-android.txt '), 'proguard-rules. Pro'
}
}

[Step 2 ]:

Add in proguard-rules.pro:
# Specify the code compression level
-Optimizationpasses 5

# Case insensitive
-Dontusemixedcaseclassnames

# Do not ignore non-public library classes
-Dontskipnonpubliclibraryclasses

# Optimize input class files
-Dontoptimize

# Pre-check
-Dontpreverify

# Whether logs are recorded during Obfuscation
-Verbose

# Obfuscation algorithm
-Optimizations! Code/simplification/arithmetic ,! Field /*,! Class/merging /*

# Protection Annotation
-Keepattributes * Annotation *

# Keep classes that are not obfuscated
-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 com. android. vending. licensing. ILicensingService
# If a v4 package is referenced, you can add the following line.
-Keep public class * extends android. support. v4.app. Fragment

 

# Ignore warning
-Ignorewarning

# Record the generated log data, which is output in the root directory of the project during gradle build ##

# Internal structure of all classes in the apk package
-Dump class_files.txt
# Unobfuscated classes and members
-Printseeds seeds.txt
# List codes deleted from the apk
-Printusage unused.txt
# Mappings before and after Obfuscation
-Printmapping mapping.txt
