Create an app

This section tells how to create a simple app with the App builder, install it on the mobile devices and receive the data from the mobile users. As an example, it describes a simple app that asks the user to enter their name and sends transaction to the Reslink server.

To create the app:

1. Open the App builder applet.

   
2. Switch to the App settings tab, click Create and fill in the fields:

   • App ID — A global ID of the Reslink application. It has to be unique across different companies to ensure that the user can have several apps installed.
   • App name — Name of the application shown in the device (max length 20 characters).
   • App icon — App icon shown in the list of apps on the device main screen. It must be a square image in the PNG format.
   • App description — Description of the app shown, for example, in the device's notications.
   • App logo — App logo shown on the login screen and in the app. It must be a square image in the PNG format.

   Note: Changing the App ID, App name and App icon fields later will require re-installing the app. Other fields can be changed without re-installing the app.

   

3. Switch to the Menu designer tab to build the app menu. Add the nodes for the app. For example, a string field where the user can enter their name. Click the new node button and define the node properties:

   • Label — Node label displayed in the app interface.
   • ID — Node ID that is used to identify the node in transactions.
   • Type — Type of node (see the Node reference section). Choose "String" to let the user enter a text string.
   

4. Click Save to save the changes.

Now the app is ready. You can install it on the mobile device and debug.
