help you fix your problem All the compress packages implement the same interface. You would use something like this to compress:
code :
var b bytes.Buffer
w := gzip.NewWriter(&b)
w.Write([]byte("hello, world\n"))
w.Close()
r, err := gzip.NewReader(&b)
io.Copy(os.Stdout, r)
r.Close()

should help you out , Try to use BufferedWriter
code :
public static String compressString(String str) throws IOException{
if (str == null || str.length() == 0) {
    return str;
}

BufferedWriter writer = null;

try{
    File file =  new File("your.gzip")
    GZIPOutputStream zip = new GZIPOutputStream(new FileOutputStream(file));

    writer = new BufferedWriter(new OutputStreamWriter(zip, "UTF-8"));

    writer.append(str);
}
finally{           
    if(writer != null){
     writer.close();
     }
  }
 }
public static String compressString(String str) throws IOException{
if (str == null || str.length() == 0) {
    return str;
}
ByteArrayOutputStream out = new ByteArrayOutputStream(str.length());
GZIPOutputStream gzip = new GZIPOutputStream(out);
gzip.write(str.getBytes());
gzip.close();

byte[] compressedBytes = out.toByteArray(); 

Gdx.files.local("gziptest.gzip").writeBytes(compressedBytes, false);
out.close();

return out.toString(); // I would return compressedBytes instead String
}

around this issue I recommend you use SSZipArchive: https://github.com/soffes/ssziparchive
Then you can do:
code :
NSString *content = @"1,2,3"
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:@"somefile.zip"];
SSZipArchive *zip = [[SSZipArchive alloc] initWithPath:path];
[zip open];
[zip writeData:[content dataUsingEncoding:NSUTF8StringEncoding] filename:@"data.csv"];
[zip close];

Hope that helps I recommend to use a Servlet Filter (since servlet 2.3 spec)
A gzip filter is well documented, so there is no need to reinvent the wheel:
