This is an android application that showcases how to implement a realtime counter using Pusher. It has a single Activity which contains a button and a count TextView. You would see the count update in realtime as you and other users tap on the button. See here for a tutorial on how this project works.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
You need to have the following before you can setup and test this project on your local machine:
- A free Pusher account
- Android Studio version 2.3 or above
- Android MinSdkVersion: 19
- Android TargetSdkVersion: 26
- Create an app on Pusher and copy your app key.
- Start the server at https://github.com/perfectmak/kotlin-realtime-counter-server-pusher.
- Clone this repository and open it with Android Studio.
- You would need to update the SERVER_URL and PUSHER_API_KEY static variables in the MainActivity.kt file to match the those of your server and pusher setup.
- Build the project and run it.
To test it out, ensure that the realtime server is running and the Android application’s SERVER_URL is updated accordingly.
Now, run the application on multiple devices. You would notice that as you click on the button, the count increases in realtime across all the devices
