Example

In this example, we will open a file that we chose from a file explorer app using a fileChooser function.

Note: This example will only work if the user has a file on their device with the suitable app to open the file.

Steps

1. Drag a button component to a page in the mobile designer, select the component and on the event press drag the fileChooser function to the event flow.

   
2. Inside the fileChooser function yes callback add the open function and fill in the parameter with input as the param type for file.

   

Result

1. Open the installed app on a device and press the button, it should open up the file explorer app so we can choose from there.

   
2. If the file and the suitable apps for opening that file exists, user should be able to see the popup where they can choose which app that they want to use for opening the file. Note: If there's only one app in the user device that's suitable for opening the file or the user had chosen a default app for opening that file type, it will automatically open that app without showing the app chooser popup.

   
3. Check the file content using previously selected suitable app.
