DonwnloadLib

一个网络下载库，支持单文件下载，断点续传下载，支持暂停，恢复，进度监听.

前期工作

在项目的build.gradle中依赖：

compile 'com.xingen:download:1.0.0'

添加相关的权限：

添加联网权限

    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

若是文件存放到sdcard需要添加，读写权限：

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

使用介绍

1.初始化：

   DownloadClient.getInstance().init(this);

例如：在Application子类中，进行初始化操作。

2. 在单线程中单文件的下载：

调用startSingleDownload(),传入下载地址，磁盘文件存放地址，进度监听器，下载状态监听器。

    private void startSingleDownload() {
        //网络的url
        String url1 = "http://imtt.dd.qq.com/16891/08637F2F36C0225E9C9BE8EAFE668B59.apk?fsname=com.shoujiduoduo.ringtone_8.7.15.0_60087150.apk";
        //文件存放路径
        String filePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + File.separator + "baidu.apk";
        singleDownloadTask = DownloadClient.getInstance().startSingleDownload(url1, filePath,
                new ProgressListener() {
                    @Override
                    public void progress(String url, int progress) {
                        Log.i(TAG, "   SingleDownload  progress " + progress);
                    }
                },
                new DownloadListener() {
                    @Override
                    public void finish(String url, String filePath) {
                        Log.i(TAG, "   SingleDownload  finish " + filePath);
                    }

                    @Override
                    public void error(String url, Exception e) {
                        Log.i(TAG, "   SingleDownload   error " + e.getMessage());
                    }
                });
    }

3. 在多线程中文件的断点续传下载：

调用startMultiDownLoadTask(),传入下载地址，磁盘文件存放地址，进度监听器，下载状态监听器。

    private void startMultiDownload() {
        String url2 = "http://yun.aiwan.hk/1441972507.apk";
        String filePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + File.separator + "baihewang.apk";
        multiDownLoadTask = DownloadClient.getInstance().startMultiDownLoadTask(url2, filePath,
                new ProgressListener() {
                    @Override
                    public void progress(String url, int progress) {
                        Log.i(TAG, "   MultiDownload   progress " + progress);
                    }
                },
                new DownloadListener() {
                    @Override
                    public void finish(String url, String filePath) {
                        Log.i(TAG, "   MultiDownload   finish " + filePath);
                    }

                    @Override
                    public void error(String url, Exception e) {
                        Log.i(TAG, "   MultiDownload   error " + e.getMessage());
                    }
                });
    }
