Android MediaPlayer背景音樂線程隨機停止

Question

我在玩的時候有一個單一的活動游戲（在登錄和角色選擇之后）。 我的 SFX 聲音池效果很好，但我的背景音樂隨機停止播放。 我嘗試添加 setOnErrorListener，但從未在那里看到任何東西。 我想知道線程是否正在被垃圾收集？

當您在不同的城鎮或荒野時，音樂會發生變化，請在此處檢查：.currentPlayingMusicFilename.equals(shortFilename)，如果您留在同一音樂區。 隨機音樂停止循環。

我在這里和谷歌上閱讀了很多帖子，找不到播放游戲背景音樂的“正確”方式。 我嘗試過 soundpool，但它們超過 1MB，看到很多東西說不提供服務，並且這種方法存在問題。 任何幫助是極大的贊賞。

我將留在“SFX”部分，以防該代碼可以幫助任何人並提供完整的圖片。

public static void playSoundOrMusic(final String shortFilename, final String type, double distanceFactor) {
    String fullFilename = "";

    if (type.equals("SFX")){
        fullFilename = "res/sounds/sfx/" + shortFilename;
    } else if (type.equals("MUSIC")){
        if (mp3MUSICPlayer != null && mp3MUSICPlayer.isPlaying() && !currentPlayingMusicFilename.equals(shortFilename)){
            mp3MUSICPlayer.stop();
        }
        fullFilename = "res/sounds/music/" + shortFilename;
    }

    float volumeManipulation = 1.0f;
    if (type.equals("SFX")){
        int sfxVolume = MyCommandReceiver.GetSharedPreferences().getInt(MyCommandReceiver.GetStringById(R.string.pref_general_sfx_volume_key), 100);
        sfxVolume *= distanceFactor;
        volumeManipulation = (float) (sfxVolume / 100.0);
        //volumeManipulation = (float) (1 - (Math.log(MAX_VOLUME - sfxVolume) / Math.log(MAX_VOLUME)));
        LoggerWrite("v", TAG, "sfxVolume: " + volumeManipulation);
    } else if (type.equals("MUSIC")){
        int musicVolume = MyCommandReceiver.GetSharedPreferences().getInt(MyCommandReceiver.GetStringById(R.string.pref_general_music_volume_key), 100);
        volumeManipulation = (float) (musicVolume / 100.0);
        //volumeManipulation = (float) (1 - (Math.log(MAX_VOLUME - musicVolume) / Math.log(MAX_VOLUME)));
        LoggerWrite("v", TAG, "musicVolume: " + volumeManipulation);

這是我解決這個問題的方法，因為它似乎沒有答案為什么它會隨機死亡。

if (type.equals("MUSIC") && (!currentPlayingMusicFilename.equals(shortFilename) || !mp3MUSICPlayer.isPlaying())){
        new Thread(new Runnable() {
        ...
