在Android上使用Jmusic混合音频

Question

I have been working on a music app for android devices for the past few months. I have written a considerable amount of code so far. However, I have been stuck for almost a month on the mixing part of the code. Since Android does not offer a way to mix audio (merge sounds into one file so that they play at the same time) I decided to add the Jmusic library to the project and use it to manipulate audio files. Unfortunately, every time I try to read an audio file from the sdcard , the app crashes. I have been looking for resource online to solve this problem, but I can't find a good one. I am thinking that maybe Android does not support the use of other libraries . Can any of you guys suggest an alternative solution if that's the case. An example code (with explanation) using Java would be greatly appreciated. What I am mainly doing is declaring a float array (data) and reading the audio file as such

     data = Read.Audio("string that holds the path of the file on the sd card");

我认为android不支持javaSE环境。在编译过程之后，android生成了dalvik代码，而java的字节代码却明显不同。
