要使用ProGuard進行代碼混淆,首先需要在項目的build.gradle文件中添加ProGuard插件的依賴:
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"
}
然后在項目根目錄下創建一個proguard-rules.pro文件,用于配置ProGuard混淆規則。根據項目的具體情況,可以在該文件中添加需要保留不混淆的類、方法等。
最后,在Android Studio中點擊菜單欄的Build -> Generate Signed Bundle/APK,選擇要發布的APK類型,并在下一步中勾選“Run ProGuard”選項,然后點擊“Finish”進行代碼混淆。
在進行代碼混淆時,需要注意確保混淆規則的準確性,避免混淆導致應用功能出現問題。建議在進行混淆后,對混淆后的代碼進行測試,確保應用的正常運行。
