Android之解决Android8.0手机(Notification)收不到自定义消息通知以及其它手机得到数据不同步

1 问题

app,自定义消息通知的时候,在Android8.0手机上收不到通知

 

 

 

 

2 解决办法

NotificationManager需要创建NotificationChannel,然后调用createNotificationChannel把NotificationChannel传递进去,并且通过setChannelId设置相应的id

 

 

 

3  普通样本代码实现

    private static final String ID = "PUSH_NOTIFY_ID";
    private static final String NAME = "PUSH_NOTIFY_NAME";
    public int id = 0; 
    public NotificationManager manager;
    public void showMessage() {
        manager = (NotificationManager) mContext.getSystemService(mContext.NOTIFICATION_SERVICE);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(mContext);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel mChannel = new NotificationChannel(ID, NAME, NotificationManager.IMPORTANCE_LOW);
            manager.createNotificationChannel(mChannel);
            builder.setChannelId(ID);
        }
