通过从数据库中获取Google云消息传递

Question

I'm working on getting news from server into the android application. Now I'm thinking of getting push notification using google cloud messaging. What I'm trying in my application is

1. Check regularly in server if there are any new data added to database.
2. if yes then make a push notification.

I'm not seeing any tutorial which does this thing. I only found android code. Please help me on this. I'm newbie to this concept.

Thanks.

Answer 1

You have to options for this:

1.. To contact your server from the app periodically and check if there are any new notifications. If so you get the data and show it to the user.

-You can do this by scheduling an alarm, maybe once a day, that starts a service that does the server checking and notifying the user. (this can be an ok solution if you know that new notifications will appear at fixed time intervals, i used it for an app that has show weekly news each Friday at noon)

2.. Google Cloud Messaging for Android

Google Cloud Messaging for Android (GCM) is a service that allows you to send data from your server to your users' Android-powered device, and also to receive messages from devices on the same connection. The GCM service handles all aspects of queueing of messages and delivery to the target Android application running on the target device. GCM is completely free no matter how big your messaging needs are, and there are no quotas.

I would recommend this if you want to be able to send notifications to users at any given time.

You have nice tutorials on developer.android, its safe and reliable and you will have complete control over the process.

I am currently working on implementing option 2, so i can update my experience on it once its done.

and here is an implementation tutorial on this one: http://www.vogella.com/articles/AndroidCloudToDeviceMessaging/article.html
