库项目不更新，而文件下载 [英] Gallery item is not updated while file downloading

问题描述

我下载从我的应用程序的视频但这视频目前无法显示的画廊，现在我只是重新启动我的设备，然后显示在画廊的项目。我不明白为什么，是任何视频标签的文件，该文件会告诉机器人在多媒体视频添加此项目设置。

I am downloading a video from my application but that video is not currently show in gallery, Now i just restart my device and then it shows in gallery item. I don't understand why, Is any video tag set with the file which will tell android to add this item in gallery video.

这是我的code

FileOutputStream fos = new FileOutputStream(filePath);

                long total = 0;
                int len = 0;

                byte[] buf = new byte[1024];

                while ((len = inputStream.read(buf)) > 0) {
                    if(!cancel)
                    {
                        fos.write(buf, 0, len);
                        // send update
                        total = total + len;


                    }
                    else
                    {
                        File f = new File(filePath);

                        System.out.println("Path is=========="+f.getAbsolutePath());

                        if(f.exists())
                            f.delete();

                        cancel = false;             

                        break;
                    }
                } 

请帮忙，谢谢提前

推荐答案

香港乐施会，我发现，只要将下载已完成我自己的问题的回答只是添加此行下方

Ohk i found my own question's answer just add this below line whenever download will have been completed

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(new File(filePath))));
