When a new post event is received, the list of post items 7 | get updated in realtime. 8 | 9 | 10 | ## Requirements 11 | - [A free Pusher account](https://pusher.com) 12 | - [Android Studio](https://developer.android.com/studio/index.html) version 2.3 or above 13 | - MinSdkVersion: 19 14 | - TargetSdkVersion: 26 15 | 16 | ## Setup Instructions 17 | 1. Create an app on Pusher and copy your app key. 18 | 2. Clone this repository and open it with Android Studio. 19 | 3. You would need to update the PUSHER_API_KEY static variables in the PusherPostDataSource.kt file to match those of your pusher setup. 20 | 4. Build the project and run it. 21 | 22 | ## Testing Instructions 23 | There are two possible ways to test this application: 24 | 25 | First (the easiest way), head over to the Debug Console of the Pusher application you created and 26 | push new post events from the Event Creator. 27 | 28 | Second way is to write a Server that would push new post events using the Pusher server libraries. 29 |
