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:
