### 解决无法发送系统通知问题 ###

在安卓8.0以上,需要开辟一个通道才能发送系统通知

private final String ID = "channel_001";
    private final String NAME = "name";
    
    @OnClick(R.id.btn_send_notifity)
        public void onViewClicked() {
        
    
            //通知管理器
            NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    
            if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        
                //开辟一个通道
                NotificationChannel mChannel = new NotificationChannel(ID, NAME, NotificationManager.IMPORTANCE_LOW);
                notificationManager.createNotificationChannel(mChannel);
                Notification.Builder builder = new Notification.Builder(this);
                //设置属性
                builder.setSmallIcon(R.mipmap.ic_launcher);
                builder.setContentTitle("标题");
                builder.setContentText("我是内容");
                //这个要和创建通道的ID一致
                builder.setChannelId(ID);
    
                //创建对象,发送的就是这个对象
                Notification build = builder.build();
                notificationManager.notify(1,build);
            }
