操作步骤：

使用video组件的页面播放视频即可复现

预期结果：

正常播放

实际结果：

视频为黑色色块、没有播放按钮、点击黑色色块也无法播放

bug描述：

video组件在开启minifyEnabled true后为黑色色块，没有播放按钮，点击也无法播放。
异常截图（图1）
关闭minifyEnabled后的正常截图（图2、3）

开启R8混淆后，加载视频播放页的logcat

欢迎到专业群（ uni-app 官方技术交流群 1 ）咨询，群中有相关专业的管理员和群友。

感谢您的反馈。针对您提交的 Bug，我们进行了初步评审与分析，具体情况如下：

1. Bug 反馈内容完整性分析

BUG 描述：描述较为清晰，明确指出了在 Android 离线打包 build.gradle 中开启 minifyEnabled true（R8 混淆）后，video 组件表现为黑色色块且无法播放的问题。
代码示例与复现步骤：存在不足。您未提供可复现的代码示例及详细的复现步骤。虽然附带了关键的 logcat 日志，但缺少具体的项目环境配置（如 HBuilderX 版本、使用的 SDK 版本等）和操作步骤，导致官方人员难以直接复现并定位。
预期与实际结果：实际结果描述符合逻辑，从日志看确实存在类找不到的异常。预期结果（正常播放）合理。
分类信息：包含了平台分类（安卓），但缺少 HBuilderX 版本号等关键版本信息。

2. Bug 是否成立分析

结合您提供的 logcat 日志，该 Bug 成立。

日志中明确报出以下异常：

java.lang.ClassNotFoundException: Didn't find class "tv.danmaku.ijk.media.player.misc.IAndroidIO"

本助手使用国产模型，生成代码可能不准确。专业的代码生成需要全球顶尖的AI Coding模型。推荐使用uni-agent
这是由于开启 R8 混淆（minifyEnabled true）后，代码混淆机制将 video 组件底层依赖的 ijkplayer 相关类（如 tv.danmaku.ijk.media.player.misc.IAndroidIO）给混淆或移除了，导致 JNI 底层在反射调用 Java 层类时找不到对应类，从而引发 ClassNotFoundException，最终导致视频无法正常初始化和播放。

3. 解决方案与建议

要解决此问题，您需要在混淆规则文件（通常是 proguard-rules.pro）中添加 keep 规则，防止 ijkplayer 及 DCloud 相关底层类被混淆。请尝试在混淆配置中添加以下规则：

# 保留 ijkplayer 相关类，避免被混淆  
-keep class tv.danmaku.ijk.media.player.** { *; }  
# 保留 DCloud 底层 media 相关类  
-keep class io.dcloud.media.** { *; }
