Android 应用程序在设置 minifyEnabled true 时崩溃

Question

启用 minifyEnabled true 时应用程序崩溃。当我将其设置为错误时，应用程序开始正常工作。我需要在我的 pro-guard 文件中添加一些内容吗？我无法弄清楚导致应用程序崩溃的原因。

Gradle 代码如下：

debug {
            manifestPlaceholders = [crashlyticsApiKey: '', mapApiKey: '']
            // Enables code shrinking, obfuscation, and optimization for only
            debuggable true
            // your project's release build type.
            minifyEnabled true
            // Enables resource shrinking, which is performed by the
            // Android Gradle plugin.
            shrinkResources true

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

            buildConfigField "String", "BASE_URL", '"http://"'
            signingConfig signingConfigs.debug
        }

Logcat 输出：

        Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

请告知我的代码有什么问题。

谢谢

错误堆栈表明： 原因：java.lang.IllegalStateException：无法读取资源实体-xhtml.properties。确保为 l.b.g.i 复制资源

我认为这是因为资源/类 l.b.g.i 被 ProGuard 排除在外。您可能希望使用 mappings.txt 文件（包含实际类/方法名称与其由 proGuard 生成的随机名称之间的映射）来解码实际资源名称，然后强制 Proguard 保留它，类似于此示例 https://stackoverflow.com/a/5866755/1992013 希望这有帮助！
