Sending an Image Failed using protocol buffer

[Lyrya]

Hi,

I want to send an image using protocol buffer in Java.

Here is my proto:

message Bitmap {

required bytes Bitmap = 1;

required float x = 2; //x position

required float y = 3; //y position

}

Here is my code in the client:

Bitmap bt = BitmapFactory.decodeResource(getResources(), R.drawable.image);

ByteArrayOutputStream baos = new ByteArrayOutputStream();

bt.compress(CompressFormat.PNG, 100, baos);

byte[] byteArray = baos.toByteArray();

Protos.Bitmap pbt = Protos.Bitmap.newBuilder()

.setBitmap(ByteString.copyFrom(byteArray))

.setX(x)

.setY(y)

.build();

Here is my code in the server:

byte[] byteArray = req.getBitmap().toByteArray();

Bitmap bt = Bitmap.createBitmap(BitmapFactory.decodeByteArray( byteArray, 0,  byteArray.length));

x = req.getX();

y = req.getY();

I don't know where the problem is.

I tried also this code in the client:

Protos.Bitmap pbt2 = pbt;

byte[] ba = pbt2.getBitmap().toByteArray();

Bitmap bt2 = BitmapFactory.decodeByteArray(ba, 0, ba.length);

canvas.drawBitmap(bt2,x,y,paint); --> this code is working

anyone has an idea??

Thanks,

Robert
