Travel Mobile App

    Pre-requisites

    While you can use any IDE of your choice suited for Java development, in this tutorial we will be working with IntelliJ IDEA. All instructions in the workshop assume this IDE.

    • IntelliJ IDEA 2019 or above downloadable from Jetbrains Developer site. The Community version is sufficient for our purposes.

    • JDK 8

    Windows Users : If you are developing on Windows, you must use a Windows 10 machine. Also, note that if you choose the Manual or Docker installation mode, you should also have administrative privileges on the Windows box so you can authorize the installation and running of the required executables.

    Travel Sample Mobile App

    • Clone the "master" branch of the Travel Sample app from GitHub. We are doing a shallow pull with depth as 1 to speed the cloning process.

      git clone -b master --depth 1 https://github.com/couchbaselabs/mobile-travel-sample.git

    • Open java/TravelSample/build.gradle using IntelliJ IDEA.

    Configure App to connect to Backend

    You will have to update the URLs specified in the app to connect to the backend If you haven’t done so already, complete the steps outlined in the "Backend Installation" to install your Couchbase Server, Sync Gateway and Python web backend app.

    Updating the web backend URL

    Open the file TryCb.java in net folder. You must update the WEB_APP_ENDPOINT constant which points to the Python Web Server.

    Now, the URLs that you specify will vary depending on the installation option that you chose for deploying your backend

    +

    • Manual

    • Docker

    • Cloud

     public static final String WEB_APP_ENDPOINT = "http://127.0.0.1:8080/api/";
     public static final String WEB_APP_ENDPOINT = "http://127.0.0.1:8080/api/";
    // Replace the hostname with the IP Address of the RightScale instance.
// The example states `54.148.83.39` but yours will be different.
 public static final String WEB_APP_ENDPOINT = "http://54.148.83.39:8080/api/";

    Updating the Sync Gateway URL

    Next, you will update the Sync Gateway endpoint.

    Open the file ReplicatorManager.java in db folder You must update the SGW_ENDPOINT constant.

    Now, the URLs that you specify will vary depending on the installation option that you chose for deploying your backend

    +

    • Manual

    • Docker

    • Cloud

    public static final String SGW_ENDPOINT = "ws://127.0.0.1:4984/travel-sample";
    public static final String SGW_ENDPOINT = "ws://127.0.0.1:4984/travel-sample";
    // Replace the hostname with the IP Address of the RightScale instance.
// The example states `54.148.83.39` but yours will be different.
public static final String SGW_ENDPOINT = "ws://54.148.83.39:4984/travel-sample";

    Try it Out

    • Build and run the project (preferrably in Debug mode)
