Channel myChannel = channelListResponse.getItems().get(0); 
     String channelId = myChannel.getId(); 
     System.out.println("channel id===" + channelId); 
     URL url = new URL(imageurl248X1152); 
     URLConnection conn = url.openConnection(); 
     InputStreamContent mediaContent = new InputStreamContent(
       "image/jpeg", conn.getInputStream()); 
     ChannelBannerResource chBannerResource = new ChannelBannerResource(); 
     YouTube.ChannelBanners.Insert chbannerresponse = youtube 
       .channelBanners().insert(chBannerResource, mediaContent); 
     ChannelBannerResource res = chbannerresponse.execute(); 
     System.out.println("res====" + res.getUrl()); 
     ChannelBrandingSettings channelBrandingSettings = new ChannelBrandingSettings(); 
     ChannelSettings channelSettings = new ChannelSettings(); 
     channelSettings.setDescription(des); 
     channelSettings.setKeywords(keyword); 
     channelSettings.setProfileColor(profilecolor); 
     ImageSettings imageSettings = new ImageSettings(); 
     imageSettings.setBannerExternalUrl(res.getUrl()); 
     channelBrandingSettings.setChannel(channelSettings).setImage(
       imageSettings); 
     Channel channel = new Channel(); 
     channel.setId(channelId); 
     channel.setBrandingSettings(channelBrandingSettings); 
     System.out.println("channel===" + channel); 
     Channel updateChannelResponse = youtube.channels() 
       .update("brandingSettings", channel).execute();
