Android New Image has strange numbers on the end of the file name

Question

I\'m writing a camera2 app in android and when I try to save the image, something adds extra numbers on the end of the filename before the \'.jpg\'

I have a feeling

Answer 1

Those random numbers are explicitly generated by createTempFile(), as seen in the source code.

You probably don't want to use temporary files anyway, thus I'd recommend to create normal files:

File image = new File(storageDirectory, imageFileName + ".jpg");
