Andorid多线程断点续传下载器

逻辑比较简单但实用的Android多线程断点续传下载器 ##Android API 版本要求 API 1 ##版本迭代 ###1.0.0 release

多线程断点续传暂未发现问题

###1.2.1 release

修复下载线程分配问题
支持域名地址重定向
如果服务器不支持断点下载则启用单线程下载且不存储于数据库

###1.3.7 release

修复域名重定向后不能进行多线程下载的问题
修复域名重定向后不能停止下载任务的问题

##预览图 在普通界面中下载

在状态栏中下载

##功能简介

多线程下载
断点续传

更多的功能方法可查看DLManager.java

##如何集成到项目 ###方式一直接从maven center compile

compile 'cn.aigestudio.downloader:Downloader:1.3.7'

###方式二自己动手 ####步骤一将Downloader这个Module导入你的Project中

####步骤二在你Project的settings.gradle文件中增加如下内容：

include ':Downloader'

这里要注意的是在一些gradle版本中需要以英文逗号的方式追加Module：

include ':YourMoudle',':Downloader'

添加后当出现“sycn now”提示时点击同步即可

####步骤三在你项目的build.gradle文件的dependencies区域中添加如下内容：

compile project(':Downloader')

##如何使用一旦将Downloader集成到项目后你便可以调用DLManager中的dlStart、dlStop和dlCancel方法来开始、停止和取消一个下载任务：

开始一个下载任务

DLManager.getInstance(context).dlStart(url, dirPath, null);

如果你需要对下载过程进行监听，可为dlStart指定一个DLTaskListener监听器：

DLManager.getInstance(context).dlStart(url, dirPath,
        new DLTaskListener() {
            @Override
            public void onProgress(int progress) {
                // 下载进行时
            }
        });

关于监听器支持的具体方法请查看DLTaskListener.java

停止一个下载任务

DLManager.getInstance(context).dlStop(url);

停止一个下载任务很简单，只需要传入url即可

取消一个下载任务

DLManager.getInstance(context).dlCancel(url);

同样地，取消一个下载任务很简单，也只需要传入url即可，取消和停止一个下载任务两者唯一的不同是前者会删除掉该次任务在数据库中所有的相关数据而停止则不会。如果你停止了一次下载任务，那么如果下次再次传入相同的url则会继续从上次停止时的位置开始下载。注意：一次下载任务的唯一标识是url。

##How to add to your project ###Method A:compile from maven center

compile 'cn.aigestudio.downloader:Downloader:1.3.7'

###Method B:Help yourself ####step 1 import Downloaderlib to your project

####step 2 Add something like below in your settings.gradle file of project:

include ':Downloader'

Note that in some other gradle version you many add module like below:

include ':YourMoudle',':Downloader'

Click 'sycn now' when it appear after module add.

####step 3 Add something like below in your build.gradle file of project:

compile project(':Downloader')

##Usage Once you add Downloader to your project you can use method dlStart dlStop and dlCancel provide by DLManager to start stop and cancel a download task:

Start a download task

DLManager.getInstance(context).dlStart(url, dirPath, null);

You can set a DLTaskListener for dlStart if you want to monitor download process:

DLManager.getInstance(context).dlStart(url, dirPath,
        new DLTaskListener() {
            @Override
            public void onProgress(int progress) {
                // when download progressing
            }
        });

You can see DLTaskListener.java for more about download listener.

Stop a download task

DLManager.getInstance(context).dlStop(url);

Just use dlStop method and transfer url to stop a download task.

Cancel a download task

DLManager.getInstance(context).dlCancel(url);

Similarly, use dlCancel method and transfer url to cancel a download task. The difference between dlStop and dlCancel is whether the data in database would be deleted or not, for example, the state of download like local file and data in database will be save when you use dlStop stop a download task, if you use dlCancel cancel a download task, anything related to download task would be deleted. note:The unique identification of a download task is url.
