Large amounts of data are added and removed often, and we would like the changes to be available to consumers in realtime. In this tutorial, we will be utilizing the Pusher Android SDK's client-side library to quickly and easily build a realtime data table.

This will send a POST request to our server. Once our server receives the POST request, it will render the data to all connected clients, which will show the data on their tables in realtime. In the build.

Sync the gradle project. However, you can find your Pusher credentials when you create an app after signing up for a free account. Be sure to keep them handy for when we start adding some realtime features. Next we define some custom button styles and layout styles to give our app the desired user interface as can be seen in the snapshots earlier posted.

So create two new drawable files called buttonstyle. These files only add round shapes to the EditText fields and LinearLayout. Hence, you could decide not to add my designs to your own work. However, to run the app with my designs and avert any xml errors, simply copy these files from the gist we attached above and paste in your own drawable files or simply delete every occurrence of buttonstyle. Your app will work just fine either way.

Then open the MainActivity. This allows us to get the text from them:. Basically, this table is temporarily serving as a mock up for our application at this point. At this point the client is set up to send the input to the server. At this point we will integrate Pusher at the back end. Pusher is a simple hosted API for quickly, easily and securely implementing realtime two-way functionality on web and mobile apps.

Generate your table-backend with:. Now install the Pusher Node library with:. Now we initialize the Pusher object in our app. Next we create the endpoint that receives JSON from the client.
