AudioFlinger无法创建曲目，状态:-12；创建AudioTrack时出错 [英] AudioFlinger could not create track, status: -12; Error creating AudioTrack
问题描述
我在SoundPool遇到问题，因为它拒绝使用我的.ogg文件.我收到此错误:
AudioFlinger could not create track, status: -12
Error creating AudioTrack
我找到了与此相关的线程以及(可能的)解决方案
主要找到了解决您这一天的方法！向下滚动！！
我和你在同一条船上.在阅读之前，我必须让您知道我没有提供可以解决此问题的答案.
我已经看到很多关于SoundPool的Stack Overflow主题，但是在Android书籍中，关于Java代码，我还没有看到很多SoundPool问题:
AudioTrack:AudioFlinger无法创建轨道，状态为-12.
SoundPool:创建AudioTrack时出错.
这是从此处提供的Beginning Android 4 Game Development源代码中摘录的代码(请参见下文).您可以在其中找到爆炸文件.(在主干中，找到第4章-Android基础知识的/asset文件夹).您必须单击右侧的查看原始文件"以获取文件.
我所做的就是将源代码直接复制到Eclipse，并将从主干提供的explain.ogg文件添加到我的项目中.我执行了Android模拟器，尝试播放了文件，然后告诉您我仍然收到上面引用的相同Logcat错误.
某人在YouTube上提供了一段视频，指出SoundPool正常工作.视频链接如下.我按照视频指示的方式进行了编码，我获取了从上面提供的第二个链接中获得的爆炸文件.我仍然遇到这些错误:
03-13 05:17:10.143:E/AudioTrack(3370):AudioFlinger无法创建曲目，状态:-12
03-13 05:17:10.143:E/SoundPool(3370):创建AudioTrack时出错
我确实知道SoundPool自Android 1.0起就处于API级别1.即使我有证据证明SoundPool可以正常工作(视频链接，第二个)，也应该没有任何理由使SoundPool无法正常工作./p>
这些是我的发现，可能会或可能不会以很好的方式帮助他人.简而言之，您并不孤单.

我能够播放SoundPool中的声音.
这是我的代码:
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);
}
}
我所做的就是重构我的代码.我是从Youtube视频链接中的一条评论中学到的，该评论的作者的名字叫"ErichLancaster".所有的功劳归他所有.我希望这对您有所帮助.
如果确实很重要，我还将Android模拟器的分辨率大小设置为QVGA.
I am having a problem With SoundPool as it refuses to work with my .ogg files. I am getting this error:
AudioFlinger could not create track, status: -12
Error creating AudioTrack
I've found a thread concerning this and the (possible) answer is:
Make sure you use .ogg media files with constant bitrate!
Is this the case? If yes - which application to use (Audacity doesn't support .ogg custom export settings). If not - what else could be wrong?
As a side note - before I used MediaPlayer but now I want to play a few sounds parallel.
MAJOR EDIT: FOUND A WAY TO FIX YOUR DAY!! SCROLL DOWN BELOW!!
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.
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 could not create track, status -12.
SoundPool: Error creating AudioTrack.
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.
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.
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:
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
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).
These are my findings and may or may not help others in a good way. In short, you're not alone here.

EDIT: I am able to play sounds from SoundPool.
Here's my 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);
}
}
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.
I also set the Android emulator resolution size to QVGA, if it really matters or not.
