What's new in v1.14 alpha (build 2025.0920.1545)

Description

From the listing uploaded by “appupdater”.

The "Redux" version is still in development and has some bugs, but addresses the issues the "Classic" version has. Calaym is a lightweight, directory/filename orientated music player. Features: - simple interface - integrated search, deleting and sharing (as provided by android/other apps) of songs - fade-in/out and crossfade - update Last.fm and/or Libre.fm if the the proper app ("Last.fm Scrobbler" or "Simple Last.fm Scrobbler") is installed (files should be properly named) - Free, ad-free, open-source - Media scanner / library independent. You can run Calaym without first having to wait for the media scanner to finish. - Lyric support. Be sure the lyric files are UTF-8 lrc files placed next to your music files. Requirements: - Android 2.1 - Music files located in external storage / memory card in folder /Music (Note the capital 'M'). Tips: - Long click the repeat mode button to toggle folder based repeat - You can click on directories / files to quickly switch to folderlist, filelist and player view - You can long-click on files to invoke a popup menu for additional options (sharing / deleting) - Long-click on the duration text to toggle between elapsed and remaining time Permissions: - Storage: modify/delete USB storage contents Allowes to delete songs, creation of .nomedia file for the music folder... - Phone calls: Read phone status and ID Calaym will fade in/out on incoming/outgoing calls
