要使用ProGuard进行代码混淆,首先需要在项目的build.gradle文件中添加ProGuard插件的依赖:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.0'
        classpath 'com.android.tools.build:gradle:7.0.3'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'com.github.dcendents.android-maven'
apply plugin: 'com.github.triplet.play'
apply plugin: 'com.github.ben-manes.versions'
apply plugin: 'com.jfrog.artifactory'
apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

def koin_version = '3.1.2'
def retrofit_version = '2.9.0'
def coroutine_version = '1.5.1'
def lifecycle_version = '2.3.1'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"
    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation "androidx.core:core-ktx:1.6.0"
    implementation "androidx.appcompat:appcompat:1.3.0"
    implementation "com.google.android.material:material:1.4.0"
    implementation "androidx.constraintlayout:constraintlayout:2.1.2"
    testImplementation "junit:junit:4.13.2"
    androidTestImplementation "androidx.test.ext:junit:1.1.3"
    androidTestImplementation "androidx.test.espresso:espresso-core:3.4.0"
    implementation "org.koin:koin-android:$koin_version"
    implementation "org.koin:koin-androidx-viewmodel:$koin_version"
    implementation "com.squareup.retrofit2:retrofit:$retrofit_version"
    implementation "com.squareup.retrofit2:converter-gson:$retrofit_version"
    implementation "com.jakewharton.retrofit:retrofit2-kotlin-coroutines-adapter:0.9.2"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$coroutine_version"
    implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
    implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"
}

然后在项目根目录下创建一个proguard-rules.pro文件,用于配置ProGuard混淆规则。根据项目的具体情况,可以在该文件中添加需要保留不混淆的类、方法等。

最后,在Android Studio中点击菜单栏的Build -> Generate Signed Bundle/APK,选择要发布的APK类型,并在下一步中勾选“Run ProGuard”选项,然后点击“Finish”进行代码混淆。

在进行代码混淆时,需要注意确保混淆规则的准确性,避免混淆导致应用功能出现问题。建议在进行混淆后,对混淆后的代码进行测试,确保应用的正常运行。
