## Prerequisites

The following prerequisites are required to use the SDK:

* Android 21+
* Latest version of Android Studio (recommended)
* Java Development Kit (JDK) 17

## Setup

1. Clone app source code locally from [this Github](https://github.com/AnchorFreePartner/hydrasdk-demo-android).
2. Launch [Android Studio](https://developer.android.com/studio) and navigate to the folder containing the recently downloaded project from Github. Once the project is open, you need to sync the project with the Gradle files. To do this, follow these steps:
   1. Click on the `File` menu in the top menu bar. From the dropdown menu, select `Sync Project with Gradle Files`. Wait for the syncing process to complete. Android Studio will download any missing dependencies and build the project.
   2. Click on the `Run` menu in the top menu bar. From the dropdown menu, select `Run 'app'`. Wait for the process to complete. It should launch Android emulator and open the demo app.

7. You are ready to connect to the VPN. To initiate the VPN connection process in the demo app:
   * Click the "init" button. No visible change will occur, which is expected behavior.
   * Click the "LOGIN" button. The app should now display a "Logged in" message, indicating successful authentication.
   * Click the "Connect" button. The app will establish the VPN connection, and display a "Connected" message upon success.
8. Your device is now connected to the VPN. To verify the connection:
   * Open the Chrome browser on your Android device.
   * Navigate to whatsmyip.com.
   * Observe that the IP address displayed is different from your device's actual IP address, confirming that traffic is being routed through the VPN.
9. To terminate the VPN connection when finished, click the "DISCONNECT" button in the demo app. This will sever the connection and restore direct network access.
