Question

I’m receiving a ZipInputStream from another source, and I need to provide the first entry’s InputStream to another source.

I was hoping to be able to do this without saving a temp file on a device, however the only way I know of getting an InputStream for an individual entry is via ZipFile.getInputStream(entry) and since I have a ZipInputStream and not a ZipFile, that is not possible.

So the best solution I have is

1. save incoming InputStream to a file
2. read file as ZipFile
3. use first entry’s InputStream
4. delete temp file.

Answer 1

figured:

it’s entirely possible, the call to ZipInputStream.getNextEntry() positions the InputStream at the start of the entry and therefore supplying the ZipInputStream is the equivalent of supplying a ZipEntry‘s InputStream.

the ZipInputStream is smart enough to handle the entry’s EOF downstream, or so it seems.
