File length is 0 when recreating file from URI, or original filepath [getExternalFilesDir(String type) vs getFilesDir()]

Question

A little bit of background first: this app takes a picture and uploads to an Azure blob storage.

The picture is stored in a file (internal storage) using getA

Answer 1

Even though I don't have all the information, I'm gonna make the call that the file is missing from the path you've given. The javadoc for length() specifically mentions this case will return 0.

So try checking exists() before you do anything with the file.
