Android DexGuard：从混淆中排除Crashlytics

Question

当我关闭DexGuard时，我的应用程序可以与Crashlytics完美运行。但是，当我添加以下配置以混淆代码时，应用程序在启动时会出现黑屏。

下面是构建的相关部分。格拉德尔

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'dexguard'

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

dependencies {
   compile fileTree(dir: 'libs', include: '*.jar')
   compile project(':MyProject')
   compile('commons-validator:commons-validator:1.4.0') {
      exclude group: 'commons-logging', module: 'commons-logging'
   }

   compile project(':android-maps-extensions')
   compile('com.crashlytics.sdk.android:crashlytics:2.5.1@aar') {
      transitive = true;
   }
}

android {
   publishNonDefault true
   compileSdkVersion 23
   buildToolsVersion "23"
   compileOptions {
      encoding "windows-1254"
   }

   defaultConfig {
    applicationId "com.x.y"
    minSdkVersion 16
    targetSdkVersion 22
    multiDexEnabled true
   }
   lintOptions {
      abortOnError false
      checkReleaseBuilds false
   }

   dexOptions{
      incremental true
      javaMaxHeapSize "4g"
      jumboMode  true
   }

   android.enforceUniquePackageName = false

   buildTypes {
      debug {
         minifyEnabled false
       }
       release {
          minifyEnabled true
          proguardFiles getDefaultDexGuardFile('dexguard-release.pro'),'dexguard-project.txt'
       }
   }
}

基本建设。渐变文件：

buildscript {
   repositories {
      flatDir dirs: System.getenv('DEXGUARD_LIB')
      jcenter()
      maven { url 'https://maven.fabric.io/public' }
   }

   dependencies {
      classpath ':dexguard'
      classpath 'com.android.tools.build:gradle:1.2.3'
      classpath 'io.fabric.tools:gradle:1.+'
   }
}

dexguard项目的相关部分。txt文件：

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-multidex

-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**

Logcat控制台输出：

Could not find method com.crashlytics.android.Crashlytics.getInstance, referenced from method com.x.y.application.MyApplication.ʻ
Could not find method com.crashlytics.android.Crashlytics.getInstance, referenced from method com.x.y.application.MyApplication.ˏ

我在用Crashlytics做什么。getInstance：

Crashlytics.getInstance().core.setString("ENVIRONMENT", "TEST");

我在生成日志中没有看到任何警告或错误。有人知道问题的原因吗？

提前谢谢！

您是否尝试过在dexGuard之后应用io.fabric？

我有一个应用程序与dexGuard和crashlytics和Crashlytics.get实例（）。core.set字符串（环境，BuildConfig。BUILD_TYPE）；不会导致错误。我使用相同的-保持和-dontwarn配置。
