无法启动服务意图 {cmp=insurancereminder.insurancereminder/insurancereminder.ReminderService (has extras) not found

Question

我正在尝试开发一个提醒应用程序，但在启动 Intent 服务时遇到问题我在 manifest.xml 中添加了必需的标签，但我仍然收到错误消息 无法启动服务意图 {cmp=insurancereminder.insurancereminder/insurancereminder.ReminderService（有附加功能）未找到。有人可以帮忙解决这个问题吗？

您无需手动编辑AndroidManifest.xml 文件。一切都应该使用[Activity]、[Intent] 和[Service] 标志注册。
