Question

What I want to do is log the output from an inputstream that I go using

org.apache.http.HttpEntity entity = response.getEntity();
org.apache.http.HttpResponse content =entity.getContent();


            //Print the result to the screen for debugging
            //puroposes
            if(Logging.DEBUG) {
                InputStream content =entity.getContent();

                int i;
                StringBuilder b = new StringBuilder();
                while( (i=content.read()) != -1 ) {
                    b.append((char)i);
                }

                Log.d(TAG, b.toString());
            }

Now after I have finished logging, I want to use the exact same stream through an XML parser. The problem is that it tells me that the steam has already been used.

I tried to the use mark() and reset() calls before and after debugging but it didn’t work.

It depends whether the inputstream that is returned supports it. The default implementation in the InputStream class does nothing, as described in the API. So you can’t be sure whether the returned Stream actually supports it. To be sure of this, you should wrap it in a BufferedInputStream, which does supports these methods.
