java - reading deflated data from the stream using inflater and InflaterInputStream -

i'm trying send deflated string on http, when use compression , decompression on server side, without using streams, it's ok when write stream this:

          byte[] deflateddata = mtext.getbyte();           try {                 t.sendresponseheaders(200,deflateddata.length);             } catch (ioexception e1) {                 display(e1);                 e1.printstacktrace();                 if(closeafter){                     t.close();                 }                 return;             }                 deflateroutputstream os = new deflateroutputstream(t.getresponsebody());           try {             os.write(deflateddata ,0,deflateddata .length);         } catch (ioexception e1) {             mbyte = null;             display(e1);             if(closeafter){                 t.close();             }             return;         }              os.flush();             os.close(); 

and read client side this:

 inflaterinputstream ini = new       inflaterinputstream(response.body().bytestream());         bytearrayoutputstream bout =new bytearrayoutputstream(512);         int b;         while ((b = ini.read()) != -1) {               bout.write(b);         }         ini.close();         bout.close();          string s=new string(bout.tobytearray()); 

android decompresses this:

 public static byte[] decompress(byte[] data) throws ioexception, dataformatexception{          inflater inflater = new inflater();           inflater.setinput(data);           bytearrayoutputstream outputstream = new bytearrayoutputstream(data.length);          byte[] buffer = new byte[1024];          while (!inflater.finished()) {           int count = inflater.inflate(buffer);           outputstream.write(buffer, 0, count);          }           byte[] output = outputstream.tobytearray();          outputstream.close();          inflater.end();         return output;         }   

so following exception:

  java.util.zip.dataformatexception: data error 

where going wrong?

the sending part totally ok , answer use inflaterinputstream directly input stream , this:

 public static string readdeflateddata(inputstream input){      inflaterinputstream in = new inflaterinputstream(input, new inflater());      int bytesread=0;     stringbuilder sb = new stringbuilder();      byte[] contents = null;     try {         contents = new byte[in.available()];     } catch (ioexception e2) {         // todo auto-generated catch block         e2.printstacktrace();     }       try {         while( (bytesread = in.read(contents)) != -1){                sb.append(new string(contents, 0, bytesread));         }     } catch (ioexception e) {         system.out.println(e.tostring());         e.printstacktrace();     }      try {         return new string(sb.tostring().getbytes(),"utf-8");     } catch (ioexception e) {         // todo auto-generated catch block         e.printstacktrace();     }      return null;  }
