Android通知适配8.0

很久以前写了一个通知的工具类，前两天拿来用，适配8.0的时候出了问题

爆了一个错误：

NotificationService: No Channel found for pkg=xxx.xxx.xxx, channelId=12345, id=12345, tag=null, opPkg=xxx.xxx.xxx, callingUid=10085, userId=0, incomingUserId=0, notificationUid=10085, notification=Notification…

突然想起来谷歌在8.0的时候对通知做了一些限制，于是去搜了一下资料

原来是要添加一个通道，绑定id

NotificationChannel channel = new NotificationChannel(id, name,NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(channel);

之前的创建方式已经被表示为过时

builder = new Notification.Builder(context);

新的创建方法要把id加里面

builder = new Notification.Builder(context, id);

于是公共方法就成了

/**
 * 普通的Notification
 */
public void postNotification() {
    Notification.Builder builder;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationChannel channel = new NotificationChannel(id, name,NotificationManager.IMPORTANCE_HIGH);
        notificationManager.createNotificationChannel(channel);
        builder = new Notification.Builder(context, id);
    }else {
        builder = new Notification.Builder(context);
    }
    //需要跳转指定的页面
    Intent intent = new Intent(context, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(pendingIntent);

    builder.setTicker("new message")
            .setSmallIcon(R.drawable.ic_launcher_background)
            .setContentTitle("标题")
            .setContentText("内容")
            .setContentIntent(pendingIntent);
activity
    notificationManager.notify(1,builder.build());
}

在activity中调用

notiUtil = new NotificationUtils(this);
notiUtil.postNotification();
