由于这些错误，我无法创建发布 APK。但我能够测试我的应用程序并成功创建调试 APK。然后我尝试创建我的旧版本代码的发布 APK，当时没有任何问题，但我仍然遇到同样的错误。
这是我的 build.gradle（应用程序）文件：

不知道为什么，但如果我将 minifyEnabled 和 shrinkResources 都设置为 false，我就能够成功创建发布 APK。但是这样应用大小就不会优化了。
我尝试在 proguard-rules.pro 中使用 -dontwarn org.xmlpull.v1.** 或 -ignorewarnings 忽略警告并且我能够生成发布 APK，但是当我启动应用程序时，它崩溃。这是崩溃的相关堆栈跟踪：

如第一个错误中所述，包 org.xmlpull.v1 存在一些问题
所以从 proguard 中忽略它们。将此规则添加到您的混淆器
-keep class org.xmlpull.v1.** { *; }
您不了解 Proguard 规则。请检查 this link 以了解 Proguard 规则。
无论您使用什么，所有 class 文件都将默认缩小。如果您正在使用任何库，您有责任通过在 proguard 规则文件中提及来保留这些 classes。
在 proguard 文件中尝试这一行
-dontwarn org.xmlpull.v1.**
