How to save a photo to phone using media api

[gazzafish]

For the life of me I cannot get the media api to save a photo to the phone under a predefined name. I am testing on Android and every time the picture gets saved in /storage/emulated/0/Pictures directory and is named “Picture1.jpg”, “Picture2.jpg” etc… I really want to select the directory it gets saved too and save it as “currentdate_currenttime.jpg”?

Hi @gazzafish,

Are you having issues with the “display.save()” call on line 76 of the posted code? There’s definitely a syntax error in that: you tell it to save “photoGroup:insert” which isn’t a reference to the photo object or the group. That would be the first thing to correct.

Take care,

Brent
