使用 Proguard 时出错

Question

我正在尝试在我的应用程序中实现 proguard，但我无法做到。我已经启用了 minifyEnabled 和 shrinkResources。这是我的 build.gradle 文件：

buildscript {

    maven { url 'https://maven.fabric.io/public' }

Answer 1

首先纠正你的 debug 和 release 部分。

 buildTypes
 {
    debug {
     shrinkResources true // This must be first 
     minifyEnabled true   // This must be after shrinkResources 
      proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }
    release {
     shrinkResources true // This must be first 
     minifyEnabled true   // This must be after shrinkResources 
      proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }

 }

Answer 2

将每个依赖项的例外添加到 proguard-rules.pro 文件中。不过，某些依赖项不需要 proguard 规则。

例如，因为你使用 retrofit ，你需要添加这个：

# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on RoboVM on iOS. Will not be used at runtime.
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions

到你的 proguard 文件
