HELP!!!!

I created a report with Jaspersoft iReport Designer 5.6.0 and the report is successfully opened on my web application ( on different browsers : IE , Firefox , Chrome , etc ) , but does not open on the Android browser . My code is:

                JasperPrint jasperPrint = JasperFillManager.fillReport(jrxml,parametri,dbcon);

                OutputStream os = response.getOutputStream();

                JRExporter exporter = null;

                response.setContentType("application/pdf");                   

                response.setHeader("Content-Disposition",  "inline; filename="report.pdf"");                                    

                exporter = new  JRPdfExporter();                    

                exporter.setParameter(JRExporterParameter.JASPER_PRINT,  jasperPrint);

                exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,  os);                                                 

                dbcon.close();                  

                exporter.exportReport();                                            

                os.close();        

Thank's
