的Soundpool：错误创建AudioTrack [英] SoundPool: Error creating AudioTrack

问题描述

我有一个问题的Soundpool，因为它拒绝与我的.ogg文件的工作。我收到此错误：

I am having a problem With SoundPool as it refuses to work with my .ogg files. I am getting this error:

AudioFlinger无法创建跟踪，状态：-12 的
 错误创建AudioTrack 的

AudioFlinger could not create track, status: -12
Error creating AudioTrack

我发现有关这个和（可能的）一个线程<一个href="http://www.anddev.org/multimedia-problems-f28/soundpool-crashing-with-could-not-create-track-t17028.html#p52455">answer是：

I've found a thread concerning this and the (possible) answer is:

• 确保您使用的.ogg媒体文件与恒定比特率！

这是如此吗？ （有人请确认或取消）
如果是的话 - 要使用的应用程序（Audacity的不支持.OGG自定义导出设置）
如果没有 - ？还有什么可能是错误的。

Is this the case? (someone please confirm or cancel)
If yes - which application to use (Audacity doesn't support .ogg custom export settings).
If not - what else could be wrong?

作为一个方面说明 - 以前我用过的MediaPlayer，但现在我想播放声音并行数

As a side note - before I used MediaPlayer but now I want to play a few sounds parallel.

推荐答案

主要编辑：找到一种方法来修复你的一天！滚动向下跌破!!

我是在同一条船上你。读书之前，我必须让你知道，我无法提供，可以解决这一问题的答案。

I'm in the same boat with you. Before reading, I must let you know that I failed to provide an answer that can fix this problem.

我看过很多很多堆栈溢出有关的Soundpool的话题，但我还没有看到很多的Soundpool问题，这方面与Java code从Android的书：

I have seen many, many Stack Overflow topics regarding SoundPool, but I haven't seen a lot of SoundPool problems with this in regard with Java code from an Android book:

AudioTrack：AudioFlinger无法创建跟踪，状态-12
  的Soundpool：错误创建AudioTrack

AudioTrack: AudioFlinger could not create track, status -12.
SoundPool: Error creating AudioTrack.

这里的code，从这里开始提供安卓4.0游戏开发源$ C ​​$ C（见下文）剪断。你得到的explosion.ogg文件存在（在树干上，找到第4章的/资产的文件夹 - Android的基础）。你必须在你的右边来获取文件点击查看原始文件。

Here's the code snipped from Beginning Android 4 Game Development source code provided here (see below). You get the explosion.ogg file there (in the trunk, find the /asset folder of Chapter 4 - Android Basics). You have to click on "View raw file" on your right to obtain the file.

我所做的只是我直接复制源$ C ​​$ C到Eclipse，并添加从树干中提供的explosion.ogg文件，到我的项目。我执行的Andr​​oid模拟器，试图播放文件，我可以告诉你，我仍然得到上面引述同一logcat中的错误。

All I did was I copied the source code directly into Eclipse, and added the explosion.ogg file provided from the trunk, into my project. I executed Android emulator, tried playing the file, and I can tell you I still get the same Logcat errors quoted above.

一个人提供的视频在Youtube上指出的Soundpool正常工作。下面的视频链接给出。我做了视频指示我code，我抓住我从上面提供的第二个链接得到了相同的explosion.ogg文件。我仍然得到这些错误：

A person provided a video on Youtube stating that SoundPool works normally. Video link is given below. I did what the video instructed me to code, I grabbed the same explosion.ogg file I got from the second link provided above. I still get these errors:

5月3日至一十三号：17：10.143：E / AudioTrack（3370）：AudioFlinger无法创建跟踪，状态：-12
  五月3日至一十三日：17：10.143：E /的Soundpool（3370）：错误创建AudioTrack

03-13 05:17:10.143: E/AudioTrack(3370): AudioFlinger could not create track, status: -12
03-13 05:17:10.143: E/SoundPool(3370): Error creating AudioTrack

我不知道的Soundpool存在由于Android 1.0，在API级别1不应该有任何理由的Soundpool到无法工作，甚至当我有证据证明的Soundpool工作（视频链接，第二一个）。

I do know that SoundPool exists since Android 1.0, at API level 1. There shouldn't be any reason for SoundPool to fail to work, even when I have proof that SoundPool works (the video link, 2nd one).

这些是我的发现，可能会或可能不会帮助别人的一个好办法。总之，你不是一个人在这里。

These are my findings and may or may not help others in a good way. In short, you're not alone here.

编辑：我能够从的Soundpool播放声音

I am able to play sounds from SoundPool.

下面是我的code：

package nttu.edu.test;

import nttu.edu.R;
import android.app.Activity;
import android.media.AudioManager;
import android.media.SoundPool;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;

public class SoundPoolTest extends Activity implements OnClickListener {
    SoundPool soundPool = null;
    int explosionId = 0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView v = new TextView(this);
        v.setOnClickListener(this);
        setContentView(v);
        this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
        v.setText("Click anywhere to play the sound.");
    }

    protected void onResume() {
        super.onResume();
        if (soundPool == null) {
            soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
            explosionId = soundPool.load(this, R.raw.explosion, 1);
        }
    }

    protected void onPause() {
        super.onPause();
        if (soundPool != null) {
            soundPool.release();
            soundPool = null;
        }
    }

    public void onClick(View v) {
        if (explosionId != 0)
            soundPool.play(explosionId, 1, 1, 0, 0, 1);
    }
}

我所做的是围绕重构我的code。我学会了这个技巧从Youtube视频链接，其中评论的作者流逝ErichLancaster的名称的意见之一。所有学分到他家里去。我希望这有助于你。

What I did was refactor my code around. I learned this tip from one of the comments in the Youtube video link, where the author of the comment goes by the name of "ErichLancaster". All credits go to him. I hoped this helped you out.

我还设置了Android模拟器分辨率大小为QVGA，如果它真的很重要与否。

I also set the Android emulator resolution size to QVGA, if it really matters or not.
