Android Byte Array to Bitmap Results Null After Receiving From Socket -

i have created server receives byte array c++ client, client send image uchar array(using opencv) , on android receiving data correctly. server on android store data byte array , need convert byte array bitmap. getting null bitmap after using bitmapfactory.decodebytearray.

here server code receives data , store in byte array

class imagereciver extends thread { public static byte imagebyte[]; private serversocket serversocket; inputstream in; int imagesize=921600;//expected image size 640x480x3     public imagereciver(int port) throws ioexception{       serversocket = new serversocket(port);    }     public void run()    {     socket server = null;        server = serversocket.accept();      in = server.getinputstream();            bytearrayoutputstream baos = new bytearrayoutputstream();     byte buffer[] = new byte[1024];              int remainingbytes = imagesize; //      while (remainingbytes > 0) {        int bytesread = in.read(buffer);        if (bytesread < 0) {          throw new ioexception("unexpected end of data");        }      baos.write(buffer, 0, bytesread);      remainingbytes -= bytesread;      }     in.close();              imagebyte = baos.tobytearray();        baos.close();     server.close();       //here conver byte array bitmap      bitmap bmp = bitmapfactory.decodebytearray(imagebyte, 0,imagebyte.length);       return;            }    } 

i seems code not correct, try this:

try {       url myurl = new url(url);       final bufferedinputstream bis = new bufferedinputstream(myurl.openstream(), 1024);       final bytearrayoutputstream datastream = new bytearrayoutputstream();       bufferedoutputstream out = new bufferedoutputstream(datastream,1024);       copy(bis, out);       out.flush();       final byte[] data = datastream.tobytearray();       bitmapfactory.options bfo = new bitmapfactory.options();       bfo.insamplesize = 2;       bitmap bm = bitmapfactory.decodebytearray(data, 0, data.length, bfo);       bis.close();        //use bitmap... } catch (exception e) {       //handle ex }
