The method checks whether the provided AudioFormat can be played
via currently connected output devices w/o SRC or downmixing
by the framework.

The new ACCESS_MEDIA_LOCATION permission is designed to protect
the location metadata of items the caller doesn't own, but we can't
easily perform partial filtering of metadata from returned Cursor
objects based on per-row ownership, so we're forced to outright stop
indexing and returning location metadata via queries.
Apps can still easily obtain location metadata using ExifInterface.

1) Fix the formula for the 'kth frequency' in getFft method:
since the 'fft' array holds n / 2 frequencies ranging from
0 to Fs / 2, the correct formula is k*Fs/n.
Also fix the last frequency index in the table.
2) Move the sample code for calculating magnitudes and phases
from the fft array from 'onFftDataCapture' to 'getFft', provide
a link.
3) Fix the sample code which wasn't taking into account that
fft[0] is the real part of FFT at DC, and fft[1] is the real part
of FFT at Fs / 2. Improve the sample code by linking the variable
names closer to the variable names in the documentation.

available() bytes is counted after the last read position,
after the seek to new position, size should be compared
with the avaliable directly (without adding position).

test: Open .heic files in Downloads/Photos that's either
very small (b/117625929, b/111897855), or with the meta

in ExifInterface.

Since not all KEYCODE_MEDIA_* keycodes return true in isMediaKey(),
the naming can give confusion. This CL renames the method to
isMediaSessionKey() and revises its Javadoc.

An upcoming privacy feature is interesting in knowing the exact
offset and length of specific Exif tags, similar to how the thumbnail
range is already being returned. Detect the case where we've modified
the underlying file, meaning ranges are no longer valid.
Add constructor to accept best-practices File object. Add method to
ask if a given tag has been defined. Add methods to parse additional
timestamp values.
