Question

我们将一个工件编译为AAR并存储在Maven存储库中。我们的工件可以添加为依赖

android {
   compileSdkVersion 23
   buildToolsVersion "23.0.2"

   defaultConfig {
       ...
       consumerProguardFiles 'proguard-rules.pro'
   }
}

我们在 build.gradle 脚本中有以下设置。

# Common
-dontoptimize
-dontobfuscate
-dontpreverify
-optimizations !code/allocation/variable
-keep public class * {
    public protected *;
}

# attributes
-keepattributes InnerClasses, Signature, *Annotation*, Exceptions

# java
-dontwarn javax.naming.**
-dontwarn java.lang.invoke**
-dontwarn java.nio.file.Files
-dontwarn java.nio.file.Path
-dontwarn java.nio.file.OpenOption
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

# retrofit
-keep class com.squareup.okhttp.** { *; }
-keep interface com.squareup.okhttp.** { *; }
-dontwarn com.squareup.okhttp.**
-dontwarn rx.**
-dontwarn retrofit.**
-keep class retrofit.** { *; }
-keepclasseswithmembers class * {
    @retrofit.http.* <methods>;
}

# gson
-keep class sun.misc.Unsafe { *; }
-keep class com.google.gson.stream.** { *; }

# otto
-keepclassmembers class ** {
    @com.squareup.otto.Subscribe public *;
    @com.squareup.otto.Produce public *;
}

# google play services
-keep public class com.google.android.gms.* { public *; }
-dontwarn com.google.android.gms.**

# support
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

文件 proguard-rules.pro 包含以下规则

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
       ...
       proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

我们正在尝试将库作为依赖项添加到包含 build.gradle 以下设置的应用

buildTypes {
    release {
        minifyEnabled true
    }

    debug {
        minifyEnabled true
    }
}

和

dependencies {
   compile fileTree(include: ['*.jar'], dir: 'libs')
   testCompile 'junit:junit:4.12'
   compile 'com.android.support:appcompat-v7:23.1.1'
   compile ('com.ourcompany:sdk:2.1.16@aar') {
      transitive = true
   }
   compile 'com.google.android.gms:play-services-location:+'
   compile 'com.google.android.gms:play-services-maps:+'
}

和

我们已经检查过我们的AAR工件中存在 proguard.txt 。我们在两种环境中测试了这种集成：

Android Studio 1.5.1结束构建过程，结果如下：第一次构建：

:app:packageDebug FAILED
Error:Execution failed for task ':app:packageDebug'.
> Unable to compute hash of D:\Workspace\AppAndroid\TestApp\app\build\intermediates\classes-proguard\debug\classes.jar

第二次构建，只是：

成功构建完成但在运行时我们遇到了由代码混淆引起的NullPointerException。

我们还尝试通过 gradlew构建项目：app：clean：app：assembleDebug 最后以

结束

非常感谢您的帮助！提前谢谢！

Answer 1

我们清除了所有缓存，从头开始重新创建项目，现在它工作正常。

尽管可用proguard.txt禁止混淆，但AAR依赖性仍然是模糊的
