I am planning to create a web based server that has additional content for my application. It is likely that this content will be sent in either XML or JSON format. How can I download content from the server and place it in a file on the device the app is on ?

Hello John,

Various things to consider here. The concept of "Download" is not something affordable for HTML apps. HTML apps can't download nor deal with the user's file system, which is reasonable, because, in other way, supose that an webpage can access to your file system... not very good, don't you?

If we have some JSON file in a server... we can just read it using an HttpClient control. If we want to save something in the client side, we can use cookies or the app's local storage, and we have actions to do this already included in App Builder like "SetOption" and "GetOption".

So we can't download files? If our app are compiled with Apache Cordova, yes, we can download files. We have actions like "FileWrite" and an specific action "FileDownload", that we can use. This actions relies in the File and File Transfer Apache Cordova plugins.

There are samples for all of these actions, so you can take a look at it, but, remember that these actions requires that our app must be compiled with Apache Cordova in order to properly work: in other words, that actions can't work in a browser without Apache Cordova.

Hi David,

Thanks for your reply. The app will be compiled using Apache Cordova. What are the names of the sample apps that you mention ?

Best Wishes
