开源Http文件下载框架file-downloader的使用

　　file-downloader（https://github.com/wlfcolin/file-downloader）是本人开源的一个Http文件下载框架，是根据自己的经验总结的一套简非常轻量级的安卓通用Http文件下载管理器。

特点：支持断点续传、多任务下载、重命名、移动、删除、自定义下载名称和保存路径等

file-downloader采用了跟安卓图片加载框架image-loader类似的设计架构，以下是使用说明和截图：

1、在你的Application的onCreate()方法中初始化FileDownloadManager

// 1.create FileDownloadConfiguration.BuilderBuilder builder = new FileDownloadConfiguration.Builder(this);// 2.builder FileDownloadConfiguration.Builderbuilder.configFileDownloadDir(Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "FileDownloader");// config the download pathbuilder.configDownloadTaskSize(3);// allow 3 download task at the same timeFileDownloadConfiguration configuration = builder.build();// config FileDownloadConfiguration with the builder// 3.init FileDownloadManager with the configurationFileDownloadManager.getInstance(this).init(configuration);

2、创建一个新下载

mFileDownloadManager.start(url, mOnFileDownloadStatusListener);

3、创建一个自定义保存文件名称和存储路径的下载

mFileDownloadManager.detect(url, new OnDetectUrlFileListener() {    @Override    public void onDetectNewDownloadFile(String url, String fileName, String saveDir, int fileSize) {        // change fileName,saveDir if needed        mFileDownloadManager.createAndStart(url, newFileDir, newFileName, mOnFileDownloadStatusListener);    }    @Override    public void onDetectUrlFileExist(String url) {        mFileDownloadManager.start(url, mOnFileDownloadStatusListener);    }    @Override    public void onDetectUrlFileFailed(String url, DetectUrlFileFailReason failReason) {        // error    }});

4、继续一个已经暂停的下载

mFileDownloadManager.start(url, mOnFileDownloadStatusListener);

5、删除下载

5-1、删除单个

mFileDownloadManager.delete(url, true, mOnDeleteDownloadFileListener);// single file

5-2、删除多个

mFileDownloadManager.delete(urls, true, mOnDeleteDownloadFilesListener);// multi files

6、移动下载文件到新文件夹

6-1、移动单个

mFileDownloadManager.move(url, newDirPath, mOnMoveDownloadFileListener);// single file

6-2、移动多个

mFileDownloadManager.move(urls, newDirPath, mOnMoveDownloadFilesListener);// multi files

7、重命名下载文件

mFileDownloadManager.rename(url, newName, true, mOnRenameDownloadFileListener);
