Java 服务类中的持续通知导致手机冻结
目前,我有一个服务类,可以在选定的时间内锁定应用程序。我试图在正在进行的通知中显示用户的剩余时间 然而,问题是,当我在手机上运行它时,它变得非常滞后,整个通知栏都被屏蔽了 我做过研究,但到目前为止运气不好 并尝试对通知使用未弃用的方法;然而,当我使用NotificationBuilder时,我的手机会断断续续。没有日志报告。我不知道该怎么办 这是我的服务课:Java 服务类中的持续通知导致手机冻结,java,android,android-service,android-notifications,Java,Android,Android Service,Android Notifications,目前,我有一个服务类,可以在选定的时间内锁定应用程序。我试图在正在进行的通知中显示用户的剩余时间 然而,问题是,当我在手机上运行它时,它变得非常滞后,整个通知栏都被屏蔽了 我做过研究,但到目前为止运气不好 并尝试对通知使用未弃用的方法;然而,当我使用NotificationBuilder时,我的手机会断断续续。没有日志报告。我不知道该怎么办 这是我的服务课: package com.ibc.android.demo.appslist.app; import android.app.Acti
