SetEventLatestInfo does not work when the project goal is raised

The Notification_quote.java file works fine when the project target is under 13. The Sdk target is no longer 26. But it gives an error. and could not run. I'm sending Notification_quote.java in the attachment. I'd appreciate it if you could help me run this. Thanks. I'm just learning coding. Someone who can tell me how to update will save me from a big problem. :)

public Notification_Quote()
{
    getQuote = null;
}

private boolean isServiceRunning(String s, Context context)
{
    boolean flag1 = false;
    Iterator iterator = ((ActivityManager)context.getSystemService("activity")).getRunningAppProcesses().iterator();
    do
    {
        do
        {
            if (!iterator.hasNext())
            {
                return flag1;
            }
        } while (!((android.app.ActivityManager.RunningAppProcessInfo)iterator.next()).processName.equals(s));
        flag1 = true;
    } while (true);
}
