DownloadManager 文件下载器

多线程下载，支持断点续传，分为Android和Java两个版本。

用法

RequestCall call = new GetBuilder()
        .name(name)
        .folder(folder)
        .uri(url)
        .tag(tag)
        .build();
DownloadManager.getInstance(this).start(call, new FileCallBack() {
    @Override
    public void onStart(String tag) {
        L.d("=====> onStart " + tag);
    }

    @Override
    public void onDownloadProgress(String tag,long finished, long totalLength, int percent) {
        L.d("=====> onDownloadProgress: " + percent);
    }

    @Override
    public void onDownloadPaused() {
        L.d("=====> onDownloadPaused: " );
    }

    @Override
    public void onDownloadCanceled() {
        L.d("=====> onDownloadCanceled: " );
    }

    @Override
    public void onDownloadFailed(DownloadException e) {
        L.d("=====> onDownloadFailed: " + e.getErrorMessage());
    }

    @Override
    public void onDownloadCompleted(File file) {
        L.d("=====> onDownloadCompleted: " + file.getAbsolutePath());
    }
});
        

简单调用

如果只想获取下载进度和结果，还可以这样调用。

new GetBuilder()
	.name("JOKER_山本彩.mp4")
	.folder(new File("F:/"))
	.uri(url)
	.tag(tag)
	.build()
	.execute(new FileCallBack() {
		@Override
		public void onStart(String tag) {
			// UI Thread
		}

	    @Override
		public void onDownloadProgress(String tag, long finished, long totalLength, int percent) {
			// UI Thread
		}

		@Override
		public void onDownloadFailed(DownloadException e) {
			// UI Thread
		}

		@Override
		public void onDownloadCompleted(File file) {
			// UI Thread
		}
	});
