Saves Image as png with 0bytes.

[DeMoN100]

I tried using this to save a photo from the vector camera app in f-droid. The photo is actually a .jpg but save on device tries to save it as a png and the file comes up 0 bytes.

I imagine you may have already found a work-around/solution, but if not could you confirm the vector camera image MIME type

area of interest for anyone with time to debug this issue.

I was able to reproduce the issue. The MIME type is image/png, unfortunately I was not able to figure out why an empty file is being sent from vector camera app, a similar app is having the same issue.

Here's my logcat output

Added wontfix label since issue appears to be originating from the Vector Camera app itself.

[dozingcat]

Yes, this was a bug in Vector Camera which should be fixed with dozingcat/VectorCamera#58. The problem was setting FLAG_ACTIVITY_NO_HISTORY in the sharing intent, which prevented save-on-device from being notified after the user had selected the save file location, which resulted in an empty file.

Sorry about that and thanks for letting me know!
