在我的应用中，用户选择的图像被打包到一个zip存档中。问题是存档中缺少许多文件（假设我选择30张图像，存档只包含12或17，可能会有所不同）。
我是否必须增加一些缓冲区值，或者为什么只有部分文件存档而其余文件丢失？
感谢。
我用来压缩的代码：
public void zip(String[] files, String zipFile) throws IOException {
File zipDirectory = new File(Environment.getExternalStorageDirectory()
+ "/laborator/");
if (!zipDirectory.exists()) {
zipDirectory.mkdirs();
} else {
System.out.println("folder already exists!");
}
BufferedInputStream origin = null;
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
new FileOutputStream(Environment.getExternalStorageDirectory()
+ "/laborator/" + zipFile)));
try {
byte data[] = new byte[BUFFER_SIZE];
for (int i = 0; i < files.length; i++) {
FileInputStream fi = new FileInputStream(files[i]);
origin = new BufferedInputStream(fi, BUFFER_SIZE);
try {
ZipEntry entry = new ZipEntry(files[i].substring(files[i]
.lastIndexOf("/") + 1));
out.putNextEntry(entry);
int count;
while ((count = origin.read(data, 0, BUFFER_SIZE)) != -1) {
out.write(data, 0, count);
}
} finally {
origin.close();
}
}
} finally {
out.close();
System.out.println("ziping done");
sendZip();
}
}
我传递给zip方法的路径列表：
