This would appear to be a bug.
I create a zip file using ZipOutputStream with success.
I can then transfer it from the tablet to my PC and look at it with WinZip.
All files have the corresponding size, compressed size, and CRC values.
Now, if I open the zip with ZipInputStream and call getNextEntry, these
values are not set.
Here is how I am reading the file :
try
{
// open the archive
FileInputStream fis = new FileInputStream(fArchive);
ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
bBuffer = new byte[2048];
// iterate through all files, putting them back into the same place
ze = zis.getNextEntry();
while(ze != null)
{
strFileName = ze.getName();
strFileName = FILE_PATH + "/" + strFileName;
fCheck = new File(strFileName);
lZipFileSize = ze.getSize(); // <--- returns -1 systematically
lTargetFileSize = fCheck.length();
fCheck = null;
FileOutputStream fos = new FileOutputStream(strFileName);
// read the data
while((iCount = zis.read(bBuffer)) != -1)
{
fos.write(bBuffer, 0, iCount);
}
fos.close();
ze = zis.getNextEntry();
}
zis.close();
fis.close();
bOk = true;
}
catch(Exception e)
{
e.printStackTrace();
}
When I look into the source for ZipInputStream, I see the following code :
if (!hasDD) {
ceCrc = ((long) Memory.peekInt(hdrBuf, LOCCRC - LOCVER, ByteOrder.
LITTLE_ENDIAN)) & 0xffffffffL;
ceCompressedSize = ((long) Memory.peekInt(hdrBuf, LOCSIZ - LOCVER,
ByteOrder.LITTLE_ENDIAN)) & 0xffffffffL;
ceSize = ((long) Memory.peekInt(hdrBuf, LOCLEN - LOCVER, ByteOrder.
LITTLE_ENDIAN)) & 0xffffffffL;
}
This is the only position that I can see where the values are retrieved,
yet it is ignored because of the !hasDD condition.
Have I misunderstood something here ?
Is this a real bug or is there an extra step to be taken ?
