    错误原因:

    • 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。
    • 如需了解详细信息,请参阅后台执行限制

    解决方案:

    在 原来启动service的地方,把startService();替换为下面的代码。

    Intent intent = new Intent(context, MyService.class);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        context.startForegroundService(intent);
    } else {
       context.startService(intent);
    }
    

    并且在service的类里面加入(若加入上面代码后正常运行可忽略此内容)

    @Override
    public void onCreate() {
        super.onCreate();
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
           startForeground(1,new Notification()); 
    }
