您的编译失败是由于Android DEX文件方法数限制（65536）导致的，当前项目方法数达73435。解决方案如下：

启用多DEX支持：在manifest.json中添加以下配置：

"android": {  
"multiDexEnabled": true,  
"mainDexList": ["com/your/package/MainActivity.class"]   
}

创建main-dex-list文件：
- 在项目根目录新建main-dex-list.txt
- 添加必须放在主DEX的类（通常是启动Activity、Application类等）
- 示例内容：
```
com/uni/app/App.class  
com/uni/app/MainActivity.class  
```
升级工具版本：确保使用HBuilderX 4.85+（当前正式版），新版本对DEX分包有优化
精简依赖：检查是否引入了不必要的第三方库，特别是uts插件中未使用的模块

注意：uni-app x编译到Android时会生成大量UTS桥接类，77个页面容易导致方法数超标。建议参考UTS插件开发文档进行代码优化，移除未使用的UTS模块。

若仍无法解决，可尝试在build.gradle中手动配置多DEX（需通过自定义构建流程实现）。更多细节请查看Android多DEX官方文档。
