如果针对 Android 8.0 的应用尝试在不允许其创建后台服务的情况下使用 startService() 函数，则该函数将引发一个 IllegalStateException。

新的 Context.startForegroundService() 函数将启动一个前台服务。现在，即使应用在后台运行，系统也允许其调用 Context.startForegroundService()。不过，应用必须在创建服务后的五秒内调用该服务的 startForeground() 函数

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

android 11startForegroundService无法启动其他应用service

添加权限 <uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>
