Android Studio obfuscation packaging and common third-party dependent obfuscation configuration

First, enable obfuscation in build.gradle, that is, minifyEnabled true. My build.gradle is as follows:

def releaseTime() {
    return new Date().format("yyyy.MM.dd", TimeZone.getTimeZone("UTC"))
}

android {
    .... 

    buildTypes {
        release {
            // confusion
            minifyEnabled true
            // Zialign optimization
            zipAlignEnabled true
            // Remove useless resource files
            shrinkResources true
            // The former part represents the obfuscation file of the system's default android program. This file already contains the basic obfuscation declaration. The latter one is its own definition obfuscation file
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

            applicationVariants.all { variant ->
                variant.outputs.each { output ->
                    def outputFile = output.outputFile
                    if (outputFile != null && outputFile.name.endsWith('.apk')) {
                        // The output APK name is appname-1.0-beta1-xx xx-xx-xx.apk
                        def fileName = "app-${defaultConfig.versionName}-beta1-${releaseTime()}.apk"
                        output.outputFile = new File(outputFile.parent, fileName)
                    }
                }
            }
        }
    }
    ....
}

proguard is written in the above notes- Android . txt file, which is the default obfuscation file of the system, is in the directory of.. / sdk/tools/proguard /. It contains the most basic obfuscation of android, which generally does not need to be changed. What we need to configure is the proguard-rules.pro file under app in the project. Here we provide a obfuscation template.

#############################################
#
# For the addition of some basic instructions
#
#############################################
# Code obfuscation compression ratio, between 0 and 7, default to 5, generally not modified
-optimizationpasses 5

# Do not use case mixing when mixing. The mixed class name is lowercase
-dontusemixedcaseclassnames

# Specifies that classes that do not ignore non-public Libraries
-dontskipnonpubliclibraryclasses

# This sentence can confuse our project and generate a mapping file
# Include the mapping relationship of class name after class name - > obfuscation
-verbose

# Specifies not to ignore class members of non-public Libraries
-dontskipnonpubliclibraryclassmembers

# Preverify is one of the four steps of proguard without pre verification. Android does not need preverify. Removing this step can speed up confusion.
-dontpreverify

# Keep annotations unambiguous
-keepattributes *Annotation*,InnerClasses

# Avoid confusing generics
-keepattributes Signature

# Keep line number when throwing exception
-keepattributes SourceFile,LineNumberTable

# Specify that obfuscation is the algorithm used, followed by a filter
# This filter is an algorithm recommended by Google, which is usually unchanged
-optimizations !code/simplification/cast,!field/*,!class/merging/*


#############################################
#
# Some common parts in Android development that need to be preserved
#
#############################################

# Keep the four major components we use, custom Application and so on, and these classes will not be confused
# Because these subclasses may be called externally
-keep public class * extends android.app.Activity

# The method parameter retained in Activity is the view method,
# In this way, the onClick we wrote in the layout will not be affected
-keepclassmembers class * extends android.app.Activity{
    public void *(android.view.View);
}

# Keep enumeration classes from being confused
-keepclassmembers enum * {
    public static **[] values();

# Keep our custom controls (inherited from View) from being confused
-keep public class * extends android.view.View{

    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);

# Keep the Parcelable serialization class from being confused
-keep class * implements android.os.Parcelable {

# Keep Serializable serialized classes unambiguous

    public void *(android.webkit.webView, jav.lang.String);

# Remove the code of log class to print logs of all levels. When you print a formal package, it can be used as a log forbidden function. Here, it can be used as a log forbidden function
# Remember that - dontoptimize must not be added to proguard-android.txt to work
# Another implementation scheme is to control through the variables of BuildConfig.DEBUG
