How to prevent app crash id image file not exist on server?

Getting Started Newbie Questions
#1

I am retrieving picture files from my server by downloading the file first to the device and then showing it. But if the file is not there then it crashes. How can I not have the app crash if the file is not there to download?

Thanks,

Warren

It’s hard to say without seeing how you are downloading the files, but you can use event.isError in your listener function: https://docs.coronalabs.com/api/library/network/download.html#download-and-display-remote-image
