I\u2019m excited to announce the release of HXAudioPlayer 4.0.0<\/strong>, the latest major update to this Android audio playback library.<\/p>\n

HXAudioPlayer<\/strong> is an Android library designed to make audio playback easier to implement by wrapping Android\u2019s MediaPlayer<\/code> and SoundPool<\/code> APIs behind a simpler interface. It was originally built for games and game-oriented Android apps, where apps often need to manage both background music and short sound effects without manually handling the complexity of multiple MediaPlayer<\/code> and SoundPool<\/code> instances.<\/p>\n

The library provides a straightforward way to play, pause, resume, loop, and manage music and sound effects with less boilerplate. It is currently used in several Y-Corner Android apps, including Dragon Geo<\/strong>, Cid\u2019s Aerial Views<\/strong>, Chrono Maps<\/strong>, Robot Master Database<\/strong>, and Map of the Nocturne<\/strong>.<\/p>\n

Version 4.0.0<\/strong> is the first major update since v3.3.1<\/strong>, which was last updated in May 2018<\/strong>. This release modernizes the library for newer Android versions, adds full support for Android 17 \/ API 37<\/strong>, and removes legacy compatibility support for API 9\u201320<\/strong>, including Android 2.3 through Android 4.4.<\/p>\n

The latest release and full changelog are available here: https:\/\/github.com\/huhx0015\/HXAudioPlayer\/releases\/tag\/v4.0.0<\/a><\/p>\n

The HXAudioPlayer repository is available here: https:\/\/github.com\/huhx0015\/HXAudioPlayer<\/a><\/p>\n

Migrating from HXAudioPlayer 3.x to 4.0.0<\/h2>\n

HXAudioPlayer 4.0.0 is a major release that modernizes the library for current Android versions. Most existing music and sound playback APIs remain familiar, but there are a few important migration notes.<\/p>\n

1. Minimum Android Version<\/h3>\n

HXAudioPlayer now requires Android 5.0 Lollipop \/ API 21 or higher<\/strong>.<\/p>\n

Support has been removed for:<\/p>\n

    \n
  • Android 2.3 Gingerbread<\/li>\n
  • Android 3.x Honeycomb<\/li>\n
  • Android 4.0 Ice Cream Sandwich<\/li>\n
  • Android 4.1\u20134.3 Jelly Bean<\/li>\n
  • Android 4.4 KitKat<\/li>\n<\/ul>\n

     <\/p>\n

    If your app still needs to support API 9\u201320<\/strong>, you should remain on the latest HXAudioPlayer 3.x release.<\/p>\n

    2. Remote Audio Playback<\/h3>\n

    For apps streaming audio from remote URLs, prefer HTTPS<\/strong>.<\/p>\n

    Because modern Android target SDK behavior blocks cleartext traffic by default, http:\/\/<\/code> URLs may fail unless cleartext traffic is explicitly enabled. If HTTP is required, use a scoped networkSecurityConfig<\/code> when possible instead of enabling cleartext traffic globally.<\/p>\n

    3. Legacy SoundPool Compatibility APIs<\/h3>\n

    A few older compatibility APIs remain, but should no longer be relied on for normal usage:<\/p>\n

    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    HXSound<\/span>.<\/span>engines<\/span>(2<\/span>);
    \nHXSound<\/span>.<\/span>reinitialize<\/span>(context<\/span>);<\/div>\n
     <\/div>\n<\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    HXSound.engines(int)<\/code> is now ignored on API 21+, and HXSound.reinitialize(Context)<\/code> is deprecated except for manual reset scenarios.<\/p>\n

    4. Threading Changes<\/h3>\n

    Music playback setup now runs through serialized background executors, making playback setup safer and less likely to block the main thread.<\/p>\n

    Most existing call sites do not need to change. However, if your app assumes playback setup happens immediately after calling play()<\/code> or resume()<\/code>, update that logic to rely on listener callbacks such as onMusicPrepared<\/code>.<\/p>\n

    5. Optional Error Handling<\/h3>\n

    HXMusicListener<\/code> now includes an optional error callback:<\/p>\n

    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    @Override<\/span>
    \npublic<\/span> void<\/span> onMusicError<\/span>(HXMusicItem<\/span> music<\/span>, int<\/span> what<\/span>, int<\/span> extra<\/span>) {
    \n\/\/ Optional: monitor MediaPlayer failures.<\/span>
    \n}<\/div>\n<\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
    \n
     <\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    Existing listener implementations should continue to work because this callback has a default implementation.<\/p>\n

    6. New Convenience APIs<\/h3>\n

    Builder-style playback still works, but v4.0.0 adds simpler helper methods:<\/p>\n

    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    HXMusic<\/span>.<\/span>play<\/span>(context<\/span>, R<\/span>.<\/span>raw<\/span>.<\/span>my_song<\/span>);
    \nHXMusic<\/span>.<\/span>play<\/span>(context<\/span>, R<\/span>.<\/span>raw<\/span>.<\/span>my_song<\/span>, true<\/span>);
    \nHXMusic<\/span>.<\/span>play<\/span>(context<\/span>, “https:\/\/example.com\/song.mp3”<\/span>);
    \nHXMusic<\/span>.<\/span>playGaplessLoop<\/span>(context<\/span>, R<\/span>.<\/span>raw<\/span>.<\/span>my_song<\/span>);
    \nHXSound<\/span>.<\/span>play<\/span>(context<\/span>, R<\/span>.<\/span>raw<\/span>.<\/span>my_sound<\/span>);
    \nHXSound<\/span>.<\/span>play<\/span>(context<\/span>, R<\/span>.<\/span>raw<\/span>.<\/span>my_sound<\/span>, true<\/span>);<\/div>\n<\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    These are optional shortcuts, so you can migrate gradually without rewriting existing builder-based playback code.<\/p>\n

    7. Position Values Use Milliseconds<\/h3>\n

    HXMusicBuilder.at(int)<\/code> expects a value in milliseconds<\/strong>.<\/p>\n

    For example:<\/p>\n

    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    \n
    .at<\/span>(5000<\/span>) \/\/ Starts playback at 5 seconds.<\/span><\/div>\n<\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
    \n
     <\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    If any older code was passing seconds instead of milliseconds, update those values during migration.<\/p>\n","protected":false},"excerpt":{"rendered":"
