Hi Francisco, I have been trying to upload video/audio files using the code you shared but I am getting below error at line "conex.getInputStream()". However, when I checked the google photos album, the entry for this video is there but it says "Your video will be ready soon" for past 6-7 hours. Can you please advise if you faced this issue and help me fix this. Thanks.
