问题描述
在样品AudioFxDemo.java，配备了SDK，我收到了
In the sample AudioFxDemo.java, provided with the SDK, I get a
java.lang.RuntimeException: Cannot initialize Visualizer engine, error: -4
试图创建android.media.audiofx.Visualizer时
when trying to create the android.media.audiofx.Visualizer
mVisualizer = new Visualizer(mMediaPlayer.getAudioSessionId());
（AudioFxDemo.java:173）。
(AudioFxDemo.java:173).
据我所看到的，在本土code ，（线路266 FF）的错误也试图创建android.media.audiofx.Equalizer时发生：
As far as I can see, the error originates in the native code, (lines 266 ff.) An error also happens when trying to create the android.media.audiofx.Equalizer:
mEqualizer = new Equalizer(0, mMediaPlayer.getAudioSessionId());
（AudioFxDemo.java:98）
(AudioFxDemo.java:98)
我收到了
java.lang.IllegalArgumentException: Effect type: 0bed4300-ddd6-11db-8f34-0002a5d5c51b not supported.
我宣布我的项目如下权限：
I have declared the following permissions for my project:
<uses-permission android:name="android.permission.RECORD_AUDIO"
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
任何想法可能什么错在这里？
Any ideas what might be going wrong here?
这似乎是与API级中的问题。我对姜饼没有问题（API等级10）。我只测试上的虚拟设备。
It seems to be a problem with the API level. I have no problems on Gingerbread (API Level 10). I have only tested on virtual devices.
推荐答案
这似乎是一个问题的模拟器。我已经测试运行的是Android 4.0.3在实际设备上和它的工作就好了。
This seems to be an issue with the Emulator. I have tested on an actual device running Android 4.0.3 and it worked just fine.
