每当我尝试在monodroid中创建一个新的音频上下文时,它会告诉我openal32.dll丢失;这自然是没有道理的,因为这是monodroid,Openal作为OpenTK的一部分包含在内。如何在monodroid中用OpenAL创建音频上下文?
我只能假设我做错了什么,但我在Windows之前使用过OpenTK/OpenAL,并且使用类似的代码管理得很好。
反正这里是有问题的代码:
public Audio()
{
if (Loaded == false)
{
Loaded = true;
try
{
try {Console.WriteLine ("Current: " + AudioContext.CurrentContext.ToString());} catch { Console.WriteLine ("no current context"); }
try {Console.WriteLine ("Default: " + AudioContext.DefaultDevice);} catch { Console.WriteLine ("no default device"); }
Context = new AudioContext();
ValidContext = true; //we have a valid audio context!
}
catch (Exception ex)
{
Console.WriteLine ("Loading the audio context failed.");
Console.WriteLine (ex.ToString());
Console.WriteLine (ex.Message);
ValidContext = false; //Loading the audio context failed :(
}
}
}
这里是输出:

感谢您的帮助,我将着眼于尝试编译OpenAL。 – Danny 2012-02-28 15:37:53
