Spring Android and GZIP Compression not being read correctly

[dmfrey]

I am writing an app that should be able to take advantage of a GZIPed response, however, when a GZIP response is detected, the following is thrown:

08-01 11:32:58.620: E/AndroidRuntime(24027): Caused by:
org.codehaus.jackson.JsonParseException: Illegal character ((CTRL-CHAR, code
31)): only regular white space (\r, \n, \t) is allowed between tokens
08-01 11:32:58.620: E/AndroidRuntime(24027): at [Source:
org.apache.http.conn.EofSensorInputStream@40890828 ; line: 1, column: 2]


The 0x31 is the ID1 character in a gziped response.

I am wondering if the JSON parser is being invoked before the GZIP handler. Just a thought.

You have to decompress the response first:

Header contentEncoding = response.getFirstHeader("Content-Encoding");
if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip" )) {
InputStream instream = new GZIPInputStream(response.getEntity().getContent()) ;
IOUtils.copy(instream, outstream);
} else {
response.getEntity().writeTo(outstream);
}
