我在启用 ProGuard 时遇到了同样的问题.按照关于此链接的建议，我通过更新我的 proguard 解决了这个问题手动.这些步骤相当容易遵循，他们解决了问题.希望这对您有所帮助.

I had the same issue when enabling ProGuard. By following the advice on this link, I fixed the issue by updating my proguard manually. The steps are fairly easy to follow and they fixed the problem. Hope this helps you.

1. 从以下位置下载 ProGuard zip 文件:https://sourceforge.net/projects/proguard/files/.在撰写本文时，ProGuard 的最新版本是 5.3.
2. ProGuard 没有安装程序，因此您需要解压缩文件并将 proguard 文件夹结构复制到以下步骤中指定的位置.
3. 启动 SDK 管理器并注意左上角菜单选项下的路径.就我而言，这是 C:UsersSaharAppDataLocalAndroidandroid-sdk.proguard 文件夹位于此路径的工具文件夹中(在我的例子中是 C:UsersSaharAppDataLocalAndroidandroid-sdk oolsproguard).
4. 关闭所有可能访问 SDK 的开发环境，并将 proguard 文件夹重命名为 proguard.old.
5. 将新版本的 proguard 文件夹复制到 tools 文件夹中，并在必要时将其重命名为 proguard(在我的情况下，复制的文件夹是从 proguard5.3 重命名的).
6. 最后将配置文件从 proguard.old 文件夹复制到新文件夹中.就我而言，这些是:-proguard-android.txt、proguard-android-optimize.txt 和 proguard-project.txt.
7. 在启用 ProGuard 的情况下清理和重建您的项目.

1. Download the ProGuard zip file available from: https://sourceforge.net/projects/proguard/files/. At time of writing the latest version of ProGuard was 5.3.
2. ProGuard does not have a setup program, so you will need to unzip the file and copy the proguard folder structure into the location identified in the steps below.
3. Launch the SDK Manager and note the path in the top left under the menu options. In my case this was C:UsersSaharAppDataLocalAndroidandroid-sdk. The proguard folder is located in the tools folder of this path (in my case this was C:UsersSaharAppDataLocalAndroidandroid-sdk oolsproguard).
4. Close any development environments that might be accessing the SDK and rename the proguard folder to proguard.old.
5. Copy the proguard folder of the new version into the tools folder and rename it to proguard if necessary (in my case the copied folder was renamed from proguard5.3).
6. Finally copy the configuration files from the proguard.old folder to the new folder. In my case these were:- proguard-android.txt, proguard-android-optimize.txt and proguard-project.txt.
7. Clean and rebuild your project with ProGuard enabled.
