插件接收音频文件 [英] plugin to receive Audio file
问题描述
我是相当新的Java和Android和我试图让使用Eclipse统一的Android插件。
I'm fairly new to Java and Android and I'm trying to make an Android plugin for Unity using Eclipse.
我们的目标是让插件播放音频文件，有效地绕过了Unity引擎的音频播放，因为统一项目的移动版本，呼吁音频播放介绍滞后。
The goal is to let the plugin play audio files, effectively bypassing the Unity Engine's audio playback since a mobile build of the unity project introduces lag in calling the audio playback.
我已经看到了它在YouTube上实现的： https://www.youtube.com/watch ？v = NyceOWbr7T4
I've seen it implemented on youtube: https://www.youtube.com/watch?v=NyceOWbr7T4
我想你可以从统一发送一个抽象的文件的插件，问题是，你怎么能跨$ P PT文件到的Soundpool对象（或资源？）$，以便它可以播放？
I figure you can send an abstract file from Unity to the plugin, the question is, how can you interpret the file into a soundpool object (or resource?) so that it can be played?
*音频文件将在Unity项目，但jar文件之外。
*The audio file would be in the Unity project, but outside of the jar file.
推荐答案
所以，我还是没能转发实际的文件（WAV），然后尝试将其转换为的Soundpool。我所做的是不同的东西：
So, I still wasn't able to forward the actual file (wav) then try to convert it to SoundPool. What I did was something different:
-
我把音频文件到StreamingAssets文件夹，这样当项目打包，我还是有机会获得这些原始文件（尽管在Android中，他们的COM pressed成jar文件）。 （就像在Venkat在公理工作室说，我希望我看到的答案越早虽然花了一些时间发现什么StreamingAssets者。）
I put the audio files into the StreamingAssets folder so that when the project is packaged, I still have access to these raw files (although in Android, their compressed into jar files). (Just like Venkat at Axiom Studios said, I wish I saw that answer sooner though, spent some time discovering what StreamingAssets were.)
使用WWW，我能够从jar文件中检索原始文件。这是从Application.streamingAssetsPath。
Using WWW, I was able to retrieve the raw files from the jar files. This is from "Application.streamingAssetsPath".
通过这些文件，我写了他们进入一个新的目录，可以通过使用File.WriteAllBytes插件方便。我用Application.persistentDataPath目录。
With these files, I wrote them into a new directory that can be easily accessible by the plugin using File.WriteAllBytes. I used the "Application.persistentDataPath" directory.
在插件方面，是的Soundpool能够从提供的URL，这是目标目录+文件名获取资源。
In the plugin side, SoundPool is able to get the resource from a provided URL, which is the destination directory + file name.
通过这个过程中，我能够最终完成我要去了，并且在性能上的改进是激烈。而我pretty高兴。
With this process, I was able to ultimately accomplish what I was going for, and the improvement in performance is drastic. And I'm pretty happy with it.
*注：然而，这使得文件的副本从包内直到安装夹（/data/data/com.example.app/files例如）。我敢肯定，你可以选择写如果文件已经存在，只是让你可以有保留原文件供以后使用，或只是删除它们时，应用程序关闭的清理之前提供的支票。
*Note: This however, makes copies of the files from inside the package unto the install folder (/data/data/com.example.app/files for example). I'm sure you can opt to provide a check before writing if the files exists already just so you can leave the files there for future use, or just delete them when the app closes as clean up.
