Answer 1

You cannot read exif data from a Stream using the android api. ExifInterface doesn't have a constructor with an InputStream.

However, You can use the metadata-extractor and use the constructor with an InputStream to build an InputStream backed by your byte[] using a ByteArrayInputStream

Answer 2

It is now possible to read EXIF data from streams through the ExifInterface Support Library.

compile "com.android.support:exifinterface:25.1.0"
