评估指令时Proguard错误 [英] Proguard error while evaluating instruction

问题描述

我将android项目升级到24 SDK版本.

I upgrade my android project to 24 SDK version.

但是在Proguard的构建路径中出现错误:

But I got error in Proguard path of build:

Unexpected error while evaluating instruction:
  Class       = [com/google/android/gms/iid/zzd]
  Method      = [zzeC(Ljava/lang/String;)V]
  Instruction = [11] invokevirtual #50
  Exception   = [java.lang.ArrayIndexOutOfBoundsException] (1)
Unexpected error while performing partial evaluation:
  Class       = [com/google/android/gms/iid/zzd]
  Method      = [zzeC(Ljava/lang/String;)V]
  Exception   = [java.lang.ArrayIndexOutOfBoundsException] (1)
Warning: Exception while processing task java.io.IOException: java.lang.ArrayIndexOutOfBoundsException: 1
:PC:transformClassesAndResourcesWithProguardForDebug FAILED

FAILURE: Build failed with an exception.

我的proguard.cfg文件:

My proguard.cfg file:

-printusage /build/proguard-usage.txt

-keep class com.android.** {*;}
-keepclassmembers class com.android.** { *; }

-keep class okio.** {*;}
-keepclassmembers class okio.** { *; }

项目中的Build.gradle:

Build.gradle in project:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

在应用程序中构建.gradle:

Build.gradle in app:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
    }
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        minSdkVersion 11
        targetSdkVersion 24
        signingConfig signingConfigs.release
    }

    buildTypes {
        debug {
            debuggable true
            minifyEnabled true
            signingConfig signingConfigs.release
            proguardFile 'proguard.cfg'
        }
        release {
            debuggable true
            minifyEnabled true
            signingConfig signingConfigs.release
            proguardFile 'proguard.cfg'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.google.android.gms:play-services-gcm:9.0.0'
    compile 'com.android.support:support-v4:24.0.0'
    compile 'com.android.support:appcompat-v7:24.0.0'
}

此配置可在22个android SDK上正常工作，但更新到24个后出现错误.

This configs work fine on 22 android SDK, but after update to 24 got error.

我尝试添加下一个，但不成功:

I try add next but not success:

-keep class com.google.android.gms.analytics.**
-keep class com.google.analytics.tracking.**
-dontwarn com.google.android.gms.analytics.**
-dontwarn com.google.analytics.tracking.**

我的错误是什么，如何解决?

What is my error and what is a solution?

推荐答案

我最终得到了以下proguard选项:

I ended up with the following proguard options:

# WORKAROUND for building project with GMS (google play services) 
-keep class com.google.android.gms.iid.zzd { *; }
-keep class android.support.v4.content.ContextCompat { *; }
