Delphi 12升级后Android 13应用启动Foreground Service崩溃求助

问题背景 #

应用在升级到Delphi 12前运行完全正常，升级后启动Foreground Service时直接崩溃，相关Android关键日志如下：

核心日志信息 #

// TAndroidHelper.Context.startService(GetIntent('com.embarcadero.services.SARTrackService'));

问题原因分析 #

从日志的核心错误点可以明确：

• JNI在注册本地方法时失败，系统提示找不到com.embarcadero.services.SARTrackServiceProxyInterface.dispatchToNative方法
• 但日志中显示该接口实际存在的是dispatchToNative2（带后缀2）的同名方法

这说明Delphi 12在生成Android服务代理类时，对JNI交互的方法命名做了变更，而旧项目的相关代码未同步适配：

1. Delphi 12重构了服务与Native层交互的逻辑，将原dispatchToNative方法重命名为dispatchToNative2
2. 项目升级后，自动生成的Java代理类（如SARTrackServiceProxyInterface）已更新为新方法名，但JNI注册逻辑仍在尝试绑定旧方法名，导致方法找不到的错误，最终触发应用崩溃
3. 也有可能是Delphi 12的RTL（运行时库）中服务代理的实现逻辑发生了变化，旧项目的服务代码未适配这种底层变更
