Android Notification推送學習

// 建立Notification相容版(compat)建構器
	            NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this,"channelid1");

   // 設定Notification點選打開Activity
   Intent intent = new Intent(MainActivity.this, MainActivity.class);
   PendingIntent pending = PendingIntent.getActivity(MainActivity.this,0, intent,0);

   builder.setSmallIcon(R.mipmap.ic_launcher_round);
   builder.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher_round))
           .setContentTitle("測試消息通知")
           .setContentText("消息通知内容，第一次不容易啊！")
           .setAutoCancel(true)
           .setDefaults(Notification.DEFAULT_SOUND)
           .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
           .setContentIntent(pending)
           .setFullScreenIntent(pending, true);

   // 建立Notification管理器
   NotificationManagerCompat manager = NotificationManagerCompat.from(MainActivity.this);

   // 執行消息通知
   manager.notify(10,builder.build());
