Just can't seem to save snapshot to Android device...

in Android Processing • 7 months ago

Hi,

Can anyone help?

I’m having real problems saving a snapshot of my display window to the DCIM folder on the Samsung Galaxy 2 tablet I’m working on…

It hasn’t got an SD card in but I’ve found the path to the gallery file: //storage//sdcard0/DCIM/Camera/myImage.jpg

I’ve looked through all the relevant forum posts I could find and followed the suggestions on the most relevant one – here…

I’ve set ‘WRITE_EXTERNAL_STORAGE’ in the Android sketch permissions… and tried out every variation of rolher’s and ak_eric’s suggestion of: save("//sdcard//DCIM/Camera/myImage.png") that seemed sensible…

I thought at first that it might be ‘doubling’ of the 2^nd forward slash but no good and I’ve seen the same format elsewhere so can’t be a typo…

I’ve tried using the ‘sdcard0’ that my device says and including ‘storage’ at the root, to try to mirror the path it reports…

The sketch is still running ok but, hard as I look, I just can’t find any saved image on my device….

Anybody any ideas? Any advice gratefully received...

Sorry if I’ve missed something obvious….

Cheers

Tom

Do you mean that the image is saved on your Samsung device, but when you use the Samsung gallery (image) viewer, the image does not show up? Because you have to tell Android to update the picture database, before it shows up in the gallery viewer. I don't have an example at the moment, but i think you can find the answer on Stackoverflow.com.

Cheers for that, el_dippo,

I'm assuming that it's saving somewhere as it's running fine not throwing any 'unknown path' type errors, but I can't find it in the Gallery - or even in what appears to be the system files...

From what you say, is it possible that it's being cached somewhere until the picture database gets updated?

Thanks for the SO heads up - I've looked on there before but usually found it a bit above my head...

Looked there briefly but couldn't see anything relevant...

I'll have another look now, looking for 'updating picture database' etc - but if you think of anything, find anything I'd be really grateful

Cheers for your help

I find it wierd that it does not show up in the file explorer. Do you use the file explorer from Windows/Mac/Linux? Because i know that there are a few file explorers on Android that work not correctly.
