Android的文件切割和合并，补全wav文件头

示例：

1、普通文件的拆分与合并：

 private void testFile() {File mWavFile = new File(getExternalFilesDir(null).getAbsolutePath() + "/test.wav");if (!mWavFile.exists()){Log.d("caowj", "文件不存在：" + mWavFile.getAbsolutePath());return;}List wavFileList = FileSplitUtils.fileSplit(mWavFile,getExternalFilesDir(null).getAbsolutePath(), 8 * 1024 * 1024);Log.d("caowj", "切割数量：" + wavFileList.size());File file2 = new File(getExternalFilesDir(null).getAbsolutePath() + "/1.wav");if(file2.exists()){List<File> list = new ArrayList<>();File file1 = new File(getExternalFilesDir(null).getAbsolutePath() + "/0.wav");File file3 = new File(getExternalFilesDir(null).getAbsolutePath() + "/2.wav");list.add(file1);list.add(file2);list.add(file3);File mergedFile = new File(getExternalFilesDir(null).getAbsolutePath() + "/merge.wav");try {if (!mergedFile.exists()){mergedFile.createNewFile();}FileSplitUtils.mergeFiles(list,mergedFile);}catch (Exception e){Log.d("caowj", "合并错误："+e.getMessage());}}else {Log.d("caowj", "分段文件不存在");}}

2、音频文件的切割，给每个切割文件补上wav头信息：

File mWavFile = new File(getExternalFilesDir(null).getAbsolutePath() + "/test.wav");
List<File> wavFileList= FileSplitUtils.wavFileSplit(mWavFile, FileUtils.getRootDataFile(this).getAbsolutePath(),15*1024*1024);

说明：wav头文件需要计算 文件长度，切割后的文件长度有变化，导致wav头文件不同；导致最终的md5值计算结果不匹配。

参考：FileUtils#waveFileHeader 方法：

public static byte[] waveFileHeader(long totalAudioLen, int bitNum, long longSampleRate, byte channels) throws IOException {}
