Flast 1.0.0

Changelog

1.0.0

First release.

A bit-perfect FLAC player for Android: 131 KB installed, roughly 15–20 MB of
RAM, no network access and no dependencies. The interface is written in C and
draws every pixel itself; the Android layer is only what the operating system
makes unavoidable — a foreground service, its notification, and USB device
detection.

Audio

• AAudio in EXCLUSIVE mode with an MMAP buffer, so the file's samples reach
  a USB DAC without resampling, mixing or volume scaling.
• A five-rung fallback ladder (EXCLUSIVE→SHARED, PCM_I32/I16/FLOAT).
  A device that will not grant exclusive mode still plays, and reports
  BIT-PERFECT: NO rather than failing.
• The stream's actual sample rate and channel count are verified after opening,
  so a stream granted at the wrong rate is rejected instead of playing an album
  at the wrong pitch.
• Bit-perfect is evaluated continuously, not once when a track starts, and
  covers sharing mode, MMAP state, output format bit depth, sample rate and
  channel layout. Any resample, up-mix or down-mix reports NO and says so.
• Track changes reuse the open stream, so the indicator does not silently
  degrade partway through an album, and the next track's file is opened while
  the current one is still playing. The silence between two tracks measures
  7–10 ms on the test device; it is not sample-exact gapless, and how large it
  is on other hardware depends on storage speed and the audio HAL.
• Audio device changes (a DAC plugged in or pulled out) pause playback with the
  position kept, and resume from the same point.

Library

• Recursive scan of internal storage and any memory card, in C via
  opendir/readdir. No dependence on a folder named "Music" and no use of
  the media database.
• Results cached between sessions; 658 tracks reload in under a millisecond.
• Browse by track or by album folder. Disc 1, CD 2 and similar folders fold
  into the album above them.
• Playlists as plain text files, one path per line.

Interface

• Two themes, four text sizes, and a bit-perfect indicator that explains itself
  when tapped.
• Playback continues in the background and survives leaving the app.

Platform

• Android 8.0 (API 26) and above — AAudio's own floor.
• armeabi-v7a, arm64-v8a, x86_64, and a universal APK containing all three.
  armeabi-v7a has never been executed on hardware; see README.
• Permissions: audio read access, foreground service, and notifications.
  No internet permission.
