Android的展台（音效）的冰淇淋三明治运行时异常 [英] Android Visualizer (Audio Effects) runtime exception on Ice Cream Sandwich

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<一个错误起源href="http://android.yongbok.net/repository/frameworks/base/media/jni/audioeffect/android_media_Visualizer.cpp"相对=nofollow>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.
