I need a workaround for the following task: I have a JPG (of whatever) picture on my sd card, and I need to send it to another device in the background. How should I do that? Best way (in theory) would be via MMS, but after a lof of searching, I can say that there is no official and trustful (and working) way to do that in the background.
Any ideas, samples, even proofs that it can be done are welcomed! All that matters is that a remote device must have access to that image.
Maybe I explained badly my needs. An important thing I missed is that the same person has access to both device. I solved it by uploading the image to google drive.
