Hello everybody, I have a mobile application for Android and I have a problem displaying images in a datawindow object with a tableblob object, when I'm designing the datawindow object in the preview, the images show fine, but when I deploy the app and test it the images are in blank.


I attach 2 images, one with the preview working fine and the second one of the mobile app with the images in blank.


I hope you can help me thank you.

Sorry, I don’t have experience with MySQL. Let’s see what other people say.

in your select statement add a computed column called imagefile. It will just be a blank space (select ' ' imagefile, ... from tablename ...)

then select each blob file you want to display, and save it as a file and store the full path in the datawindow : yourdw.setitem( row, 'imagefile', ls_blobfilename)

you can use bitmap function to display it in another compute field, or use the display as picture option for your column (see "bitmapname" NOT "display as picture" in help because having it consistent with the name on the actual datawindow editor would make too much sense. )
