# Android-specific MIME type <-> extension mappings
#
# Each line below defines a mapping from one MIME type to the first of the
# listed extensions, and from listed extension back to the MIME type.
# A mapping overrides any previous mapping _from_ that same MIME type or
# extension (put() semantics), unless that MIME type / extension is prefixed with '?'
# (putIfAbsent() semantics).
#
#
###############################################################################
#
# EXAMPLES
#
# A line of the form:
#
#    ?mime ext1 ?ext2 ext3
#
# affects the current mappings along the lines of the following pseudo code:
#
#    mimeToExt.putIfAbsent("mime", "ext1");
#    extToMime.put("ext1", "mime");
#    extToMime.putIfAbsent("ext2", "mime");
#    extToMime.put("ext3", "mime");
#
# The line:
#
#     ?text/plain txt
#
# leaves any earlier mapping for "text/plain" untouched, or maps that MIME type
# to the file extension ".txt" if there is no earlier mapping. The line also
# sets the mapping from file extension ".txt" to be the MIME type "text/plain",
# regardless of whether a previous mapping existed.
#

# File extensions that Android wants to override to point to the given MIME type.
#
# After processing a line of the form:
# ?<mimeType> <extension1> <extension2>
# If <mimeType> was not already mapped to an extension then it will be
# mapped to <extension1>.
# <extension1> and <extension2> are mapped (or remapped) to <mimeType>.

# Optional additions that should not override any previous mapping.

# Special cases where Android has a strong opinion about mappings, so we
# define them very last and make them override in both directions (no "?").
#
# Lines here are of the form:
# <mimeType> <extension1> <extension2> ...
#
# After processing each line,
#   <mimeType> is mapped to <extension1>
#   <extension1>, <extension2>, ... are all mapped to <mimeType>
# This overrides any mappings for this <mimeType> / for these extensions
# that may have been defined earlier.
