如何使用电话号码将通知从Android应用发送到另一个Android设备？

Question

I am developing an android application and i need to send a notification from the app to a phone number (another device).

Can anyone tell me how can i implement this? any methods or API i can use?

Thank you in advance

Answer 1

I don't think you can do it without developing server-side software that Android devices will connect to. In your server-side software you can use FCM(Firebase Cloud Messaging) or any other framework/library to send notifications to one or group of devices.

Problem is that you need to have connection to the other device and you can't know if that device is connected to internet and even if it is you don't know the address of that device. 99.99% that you need server-side software.

Answer 2

the easiest way (but the most expensive i guess) is to have the first device send a request to a server (whose backend you have to build, eg. php) that will send a push notification to the second device via Google Cloud messaging service.

that's not so easy because the second device to receive the notification must register at GCM and the first device must identificate the id of this device (the common way is to have a common id like username)

Answer 3

There is on possibility without using server side code, Send SMS to the second Phone and read the SMS in second phone and display your notification in second phone. It will cost the SMS charges in both phones.

Answer 4

Create an API that communicates with the users of the application this will be able to send updates to the registered users at real-time. http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/
