Các vấn đề về Proguard với Gradle 3.0.0

Question

Tôi đang cố gắng tạo APK bằng ProGuard và phiên bản Gradle 3.0.0 mới. Tôi nhận được rất nhiều cảnh báo về các lớp học mà tôi nghĩ rằng tôi bỏ qua trong tập tin cấu hình ProGuard của tôi. Các cấu hình tương tự hoạt động tốt với Gradle 2.3.3 nhưng dường như phá vỡ trên 3.0.0. Các cảnh báo rất nhiều, hầu như không đọc được cấu hình ProGuard.

build.gradle My

buildscript { 
    repositories { 
     mavenCentral() 
     jcenter() 
     google() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.3' 
     classpath 'com.google.gms:google-services:3.0.0' 
     classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5' 
     classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2' 


    } 

} 


allprojects { 
    repositories { 
     jcenter() 
     maven { 
      url 'https://jitpack.io' 
     } 
     maven { 
      url 'https://maven.google.com' 
     } 

    } 
} 
android{ 
buildTypes { 
     release { 
      minifyEnabled true 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 
        'proguard-rules.pro' 
      signingConfig signingConfigs.release 
      lintOptions { 
       disable 'MissingTranslation' 
      } 

     } 




compileSdkVersion 27 
buildToolsVersion "27.0.1" 
defaultConfig { 
minSdkVersion 16 
targetSdkVersion 27 
testInstrumentationRunner

}

Answer 1

Tôi đã nâng cấp lên phiên bản 3.0.1 và hầu hết các cảnh báo đã biến mất. Nếu bạn vẫn còn trên 3.0.0 thì hãy sử dụng điều này trong tập tin bảo vệ của bạn

-dontwarn android.** 

Không lý tưởng nhưng nó hoạt động.

Answer 2

Thêm bên dưới mã trong android thẻ

lintOptions { 
     // set to true to turn off analysis progress reporting by lint 
     quiet true 
     // if true, stop the gradle build if errors are found 
     abortOnError false 
     // if true, only report errors 
     ignoreWarnings true 
    } 

Answer 3

Nó có thể giúp bạn Enabling ProGuard for local library modules no longer affects the library's code. Instead, you should run ProGuard on the app module that consumes the library. https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

Answer 4

tôi đã cùng một vấn đề, mặc dù trường hợp của tôi là loại độc đáo, đây là giải pháp của tôi :

Sau khi nâng cấp lên phiên bản 3.0.1 mới (com.android.tools.build:gradle:3.0.1), tôi thấy ít cảnh báo hơn (ban đầu tôi có> 3000 cảnh báo). Nguồn gốc của vấn đề của tôi là tôi đã sử dụng thư viện có phụ thuộc vào toàn bộ khung công tác android (Điều này: https://github.com/tony19/logback-android, số phát hành #73).

Tôi cũng đã xem xét các phụ thuộc (./gradlew app:dependenices), bởi vì tôi có các thư viện phụ thuộc vào ứng dụng http apache cũ, cũng gây ra một số cảnh báo. Tôi cũng phải loại bỏ chúng.
