Question

当R8与现有的proguard配置一起启用时，我在发布版本中得到了RuntimeException。顺利检查了"Failure to verify dex file Out-of-order annotation_element name_idx"，我还没有在任何地方设置-overloadaggressively。还尝试根据"Android/java: Transition / Migration from ProGuard to R8?"在禁用ProGuard的情况下仍然无法使用。

构建环境如下：

Android Studio : 3.4.1
com.android.tools.build:gradle:3.4.1

android.enableR8=true
android.enableD8=true
android.enableDesugar=true

崩溃日志：

Answer 1

在Proguard以前可以正常工作的情况下，我为此苦苦挣扎了一段时间，但是当R8作为默认代码收缩器引入时，它从我的应用程序中剥离了所需的资源。我终于恢复到使用行如下的老派Proguard了：

在gradle.properties中添加：
android.enableR8 = false

在build.gradle中添加：
useProguard = true

修改两个文件很重要，否则R8将在Android Studio 3.4+中自动启用

Answer 2

R8和D8中都存在此问题，https://issuetracker.google.com/136549275中对此进行了跟踪。

问题解决后，我将更新此答案。

使用现有的Proguard设置启用R8后，应用程序崩溃
