2 原因分析
Android go 不再允许后台service直接通过startService方式去启动， 具体行为变更如下：
如果针对 Android go 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。
3 解决方法
注意点：要修改对应的启动的类
我们这里要修改这里。
