NotificationCompat with API 26

Question

I dont see any information about how to use NotificationCompat with Android O's Notification Channels

I do see a new Constructor that takes a channelId but how to take a Compat notification and use it in a NotificationChannel since createNotificationChannel takes a NotificationChannel object

Answer 1

Create the NotificationChannel only if API >= 26

public void initChannels(Context context) {     if (Build.VERSION.SDK_INT < 26) {         return;     }     NotificationManager notificationManager =             (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);     NotificationChannel channel = new NotificationChannel("default",                                                           "Channel name",                                                           NotificationManager.IMPORTANCE_DEFAULT);     channel.setDescription("Channel description");     notificationManager.createNotificationChannel(channel); } 

And then just use:

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context, "default"); 

So your notifications are working with both API 26 (with channel) and below (without).
