Please change the code in ReceivingTask.java: detected[i].prob = (float)(ByteBuffer.wrap(tmp).order(ByteOrder.LITTLE_ENDIAN).getFloat()); to detected[i].prob = (float)(ByteBuffer.wrap(tmp).order(ByteOrder.LITTLE_ENDIAN).getInt());

When we want show more results on SurfaceView, please increase the Conatants.REG_SIZE (client) and ServerUDP.REG_SIZE (server)

For better plot bundle boxes, maybe you need rewrite onDraw() method. The resolution of my phone is 2227*1080. In MainActivity class, I rewrite onDraw() method as follows:

	@Override
    protected void onDraw(final Canvas canvas) {
        super.onDraw(canvas);
        if(detecteds != null) {
            for (Detected detected : detecteds) {
                float height_adjust = 8.3f;
                canvas.drawRect((detected.left)*7-5, (detected.top)*height_adjust-50,
                        (detected.right)*7, (detected.top)*height_adjust, paintBackground);
                canvas.drawText(detected.name +  " " + detected.prob,
                        (detected.left)*7, (detected.top)*height_adjust-10, paintWord);
                canvas.drawRect((detected.left)*7, (detected.top)*height_adjust,
                        (detected.right)*7, (detected.bot)*height_adjust, paintLine);
            }
        }
    }
