更新到Google Play Services 11.8.0后，ProGuard不工作

Question

将Google Play服务更新到11.8.0（从11.6.2）后，我的构建停止工作。

这就是我得到的：

计算堆栈大小时出现意外错误：Class=[com/google/android/gms/内部/zzao]method=[zzf（Ljava/lang/String；）J]Exc0019=[java.lang.IllegalArgumentExc0019]（堆栈大小在[com/google/android/gms/内部/中的[23]invokestatic#146指令后变为负数zzao.zzf（Ljava/lang/String；）J]）失败：构建失败，有一个异常。

我正在使用Android Studio 3.0.1和Gradle 4.4.1

Answer 1

我也有类似的问题。正如本文中所建议的，您只需要在构建中添加这些行。gradle文件：

...
release {
   debuggable false
   useProguard true
   ...
}
...

我也不得不删除亲后卫优化更换：

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

通过

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

Answer 2

你不需要完全禁用优化，只需要对问题类进行优化。我也有同样的问题，通过在proguard规则中添加以下内容来解决。专业文件：

-keep class com.google.android.gms.internal.** { *; }
