Hi everyone,
I’m currently working on a mobile app project using ODC (OutSystems Developer Cloud). After click file name in the UI, I need to download files (jpg, xlsx, etc.) that are returned from a Server Action in binary (base64) format.
I’m using File Transfer Plugin/WriteFile to create a local file and then use the returned URI. Along with that, I use File Viewer Plugin/OpenDocumentFromLocalPath with returned URI to preview the file, where Forge provides options for users to download. Currently working perfectly.
However, I now have a new requirement:
I want the file to start downloading immediately when the user clicks the file name
I do not want to open the preview screen
What I’ve tried so far:
Download Manager Plugin, but it doesn’t seem to work properly on iOS
FileTransferPlugin / DownloadFile, but it keeps throwing variable-related errors
Has anyone faced this issue before or knows how to handle this scenario?
Thanks in advance for your help.
You can use js to create a link then click on the link to download the file. Please refer to the js sample below
Hi Shingo, I think JS does not work on mobile application
Hi @Alan Nguyen
On mobile (especially iOS), files are not downloaded in the traditional sense like desktop browsers. The OS usually requires either:
For your requirement (download immediately without preview), instead of trying to skip interaction completely, change flow to:
If your goal is zero user interaction, I think it's not realistically supported on iOS due to security restrictions.
