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确定的位置.
3. 启动SDK Manager，并注意菜单选项下左上角的路径.在我的情况下，这是C:\ Users \ Sahar \ AppData \ Local \ Android \ android-sdk. proguard文件夹位于该路径的工具文件夹中(在我的情况下为C:\ Users \ Sahar \ AppData \ Local \ Android \ android-sdk \ tools \ proguard).
4. 关闭所有可能正在访问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，并在必要时将其重命名为proguard(在我的情况下，复制的文件夹已从proguard5.3重命名).
6. 最后将配置文件从proguard.old文件夹复制到新文件夹.就我而言，这些是: proguard-android.txt，proguard-android-optimize.txt和proguard-project.txt.
7. 在启用ProGuard的情况下清理并重建项目.

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:\Users\Sahar\AppData\Local\Android\android-sdk. The proguard folder is located in the tools folder of this path (in my case this was C:\Users\Sahar\AppData\Local\Android\android-sdk\tools\proguard).
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.
