问题描述

我正在我的Android版本7.1.1中测试均衡器，但它显示了运行时异常，但在7.0以下版本中可以正常运行.

I am testing equalizer in my Android Version 7.1.1 but it shows a Runtime Exception but It's perfectly working on below version 7.0.

当我尝试初始化均衡器时:

When I try to initialize equalizer :

private static UUID EQUALIZER_UUID;
mp = MediaPlayer.create(this, R.raw.a);
mp.start();
if(hasEqualizer()) {
   equalizer = new Equalizer(0, mp.getAudioSessionId());
   equalizer = equalizerUtil.getEqualizer(mp);
   Log.d("No. of Presets",String.valueOf(equalizer.getNumberOfPresets()));
}

public static boolean hasEqualizer() {
    for (AudioEffect.Descriptor effect : AudioEffect.queryEffects()) {
        if (EQUALIZER_UUID.equals(effect.type)) {
            return true;
        }
    }
    return false;
}

它显示错误:

推荐答案

如果会话ID尚不可用，可能似乎是getAudioSessionId()的问题.在以下链接的线程上查看此响应:

It looks like it might be an issue with getAudioSessionId() if a session ID isn't available yet. See this response on the thread linked below:

这意味着尚未设置.您可以使用 player.setAudioDebugListener侦听正在设置的ID(ID 将会通过onAudioSessionId传递).

That means it hasn't been set yet. You can use player.setAudioDebugListener to listen for the ID being set (the ID will be passed via onAudioSessionId when it is).
