Hyperlink to Local Image on Android Device

Question

Hi,

I am using Field Maps on an Android tablet running Android 14 and 15. Is it possible to create a hyperlink to an image stored locally on the device? I need a way to link to an image on the SD card, such as:

/storage/3937-3362/Pictures/foo_location1.tif

then open it with a viewer

Thanks for your help.

Thank you for replying. I created a small web server to access local images, but with Android’s upcoming changes to the security model, this approach will no longer be supported. I’m looking for an alternative method to reference local files directly—ideally from within the same sandboxed storage area, for example: file:\field_maps\images\IMAGE1.TIF.

I also experimented with using attachments, but there appears to be a rendering issue with larger image files. As the file size increases, the images become distorted, making this option unsuitable for my use case.

Thanks for your help.

I tried this many years ago and Android changes that path per device so its never static. Esp SD card they name it some serial like RY55HHJ/files.   Some security issue.

In 123 we build the help images right into the form.  Not sure if Field Maps has that.
