AWS/Android Unable to calculate md5 hash

I'm customising Amazon's S3 Uploader sample program to suit my needs. After a bucket is created, I upload a video to it.

PutObjectRequest por = new PutObjectRequest(buckets.get(0).getName(), Constants.VIDEO_NAME, new java.io.File(filePath));

When I run the line above I get back the exception below:

Unable to calculate MD5 has: /storage/....../bla.mp4: open failed: EACCES (Permission Denied)

Stack Trace:

OS = 4.4/KitKat, Device = Nexus 4

What's going on?

Don't be like me. Check that the file exists before attempting to upload to S3.

From KitKat, you can't read external storage without the permission.

See
