如何使android前台服务通知在中文ROM中具有粘性?
我试着在后台使用前台服务运行这项服务,除了维梧、oppo、oneplus等中国设备外,它在所有设备上都能正常工作。这些设备会在应用程序从最近列表中删除后立即删除该服务 甚至前台通知也不是粘性的。它可以游泳。然而,我想在它被清除后再次显示通知,有什么办法吗 例如,我在IDM(Internet下载管理器)等应用程序中看到,当下载任何文件时,通知仍然可见。即使被清除,通知也会再次弹出 如何获得这种类型的功能 我的代码: MainActivity.java如何使android前台服务通知在中文ROM中具有粘性?,android,foreground-service,notification-channel,foregroundnotification,Android,Foreground Service,Notification Channel,Foregroundnotification,我试着在后台使用前台服务运行这项服务,除了维梧、oppo、oneplus等中国设备外,它在所有设备上都能正常工作。这些设备会在应用程序从最近列表中删除后立即删除该服务 甚至前台通知也不是粘性的。它可以游泳。然而,我想在它被清除后再次显示通知,有什么办法吗 例如,我在IDM(Internet下载管理器)等应用程序中看到,当下载任何文件时,通知仍然可见。即使被清除,通知也会再次弹出 如何获得这种类型的功能 我的代码: MainActivity.java @Override prot
