|
|
|
|
Aria项目源于15年工作中遇到的一个文件下载管理的需求，当时被下载折磨的痛不欲生，从那时起便萌生了编写一个简单易用，稳当高效的下载框架，aria经历了1.0到3.0的开发，算是越来越接近当初所制定的目标了。 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Aria有以下特点： |
|
|
|
|
|
|
|
+ 简单、方便 |
|
|
|
|
|
|
|
- 可以在Activity、Service、Fragment、Dialog、popupWindow、Notification等组件中使用 |
|
|
|
|
|
|
|
- 支持任务自动调度，使用者不需要关心任务状态切换的逻辑 |
|
|
|
|
|
|
|
- [通过Aria的事件，能很容易获取当前下载任务的下载状态](#下载状态获取) |
|
|
|
|
|
|
|
- [一句代码加可以获取当前的下载速度](#常用接口) |
|
|
|
|
|
|
|
- [一句代码就可以动态设置最大下载数](#代码中设置参数) |
|
|
|
|
|
|
|
- [通过修改配置文件很容易就能修改下载线程数](#配置文件设置参数) |
|
|
|
|
|
|
|
+ 支持https地址下载 |
|
|
|
|
|
|
|
- 在配置文件中很容易就可以设置CA证书的信息 |
|
|
|
|
|
|
|
+ 支持300、301、302重定向下载链接下载 |
|
|
|
|
|
|
|
+ 支持上传操作 |

|
|
|
|
## 使用 |
|
|
|
|
|
|
|
由于Aria涉及到文件和网络的操作，因此需要你在manifest文件中添加以下权限 |
|
|
|
|
|
|
|
```xml |
|
|
|
|
|
|
|
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/> |
|
|
|
|
|
|
|
<uses-permission android:name="android.permission.INTERNET"/> |
|
|
|
|
|
|
|
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 使用Aria进行下载 |
|
|
|
|
|
|
|
* 添加任务（不进行下载），当其他下载任务完成时，将自动下载等待中的任务 |
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this) |
|
|
|
|
|
|
|
.load(DOWNLOAD_URL) |
|
|
|
|
|
|
|
.setDownloadPath(Environment.getExternalStorageDirectory().getPath() + "/test.apk") //文件保存路径 |
|
|
|
|
|
|
|
.add(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* 下载 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this) |
|
|
|
|
|
|
|
.load(DOWNLOAD_URL) //读取下载地址 |
|
|
|
|
|
|
|
.setDownloadPath(Environment.getExternalStorageDirectory().getPath() + "/test.apk") //设置文件保存的完整路径 |
|
|
|
|
|
|
|
.start(); //启动下载 |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 暂停 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this).load(DOWNLOAD_URL).pause(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 恢复下载 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this).load(DOWNLOAD_URL).resume(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 取消下载 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this).load(DOWNLOAD_URL).cancel(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 下载状态获取 |
|
|
|
|
|
|
|
如果你希望读取下载进度或下载信息，那么你需要创建事件类，并在onResume(Activity、Fragment)或构造函数(Dialog、PopupWindow)，将该事件类注册到Aria管理器。 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* 将对象注册到Aria |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
` Aria.download(this).register();`或`Aria.upload(this).register();` |
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
@Override protected void onCreate(Bundle savedInstanceState) { |
|
|
|
|
|
|
|
super.onCreate(savedInstanceState); |
|
|
|
|
|
|
|
Aria.download(this).register(); |
|
|
|
|
|
|
|
} |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
* 使用'@Download'或'@Upload'注解你的函数 |
|
|
|
|
|
|
|
**注意：** |
|
|
|
|
|
|
|
- 注解回掉采用Apt的方式实现，所以，你不需要担心这会影响你机器的性能 |
|
|
|
|
|
|
|
- 被注解的方法**不能被private修饰** |
|
|
|
|
|
|
|
- 被注解的方法**只能有一个参数，并且参数类型必须是`DownloadTask`或`UploadTask`** |
|
|
|
|
|
|
|
- 方法名可以为任意字符 |
|
|
|

|
|
|
|
|
```java |
|
|
|
|
|
|
|
@Download.onPre protected void onPre(DownloadTask task) {} |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
@Download.onTaskStart void taskStart(DownloadTask task) { |
|
|
|
|
|
|
|
//通过下载地址可以判断任务是否是你指定的任务 |
|
|
|
|
|
|
|
if (task.getKey().equals(DOWNLOAD_URL)) { |
|
|
|
|
|
|

} |

|
|
|
@Download.onTaskStop void taskStop(DownloadTask task) {} |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
@Download.onTaskCancel void taskCancel(DownloadTask task) {} |
|
|
|

|
|

@Download.onTaskFail void taskFail(DownloadTask task) {} |
|
|
|
|

|
|
|
|
|
|
|
|
|
|
@Download.onTaskComplete void taskComplete(DownloadTask task) {} |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
@Download.onNoSupportBreakPoint public void onNoSupportBreakPoint(DownloadTask task) {} |
|
|
|
|
|

|
|
|

``` |

### 使用广播接收器接收Aria的任务下载状态 |
|
|
|
|
|
|
|
有的时候，你可能希望在广播中接收Aria的下载事件，那么你需要 |
|
|
|
|
|
|
|
* 在[配置文件](#配置文件设置参数)中把` <openBroadcast value="false"/>`中的value改为true |
|
|
|
|
|
|
|
* [点击该链接查看注册Aria广播的方式](https://github.com/AriaLyy/Aria/blob/master/BroadCast.md) |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### Aria参数配置 |
|
|
|
|
|
|
|
#### 配置文件设置参数 |
|
|
|
|
|
|
|
创建`aria_config.xml`文件，将其放在`assets`目录下，添加以下内容 |
|
|
|
|
|
|
|
```xml |
|
|
|
<?xml version="1.0" encoding="utf-8"?> |
|
|
|
<?xml version="1.0" encoding="utf-8"?> |
|
|
|
<aria> |
|
|
|
<aria> |

``` |

|
|
|
|
|
|
|
|
|
|
|
|
|
#### 代码中设置参数 |
|
|
|
|
|
|
|
除了文件方式外修改Aria参数外，同样的，你也可以在代码中动态修改Aria参数</br> |
|
|
|
|
|
|
|
通过`Aria.get(this).getDownloadConfig()`或`Aria.get(this).getUploadConfig()`直接获取配置文件，然后修改参数</br> |
|
|
|
|
|
|
|
如以下所示： |
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
// 修改最大下载数，调用完成后，立即生效 |
|
|
|
|
|
|
|
// 如当前下载任务数是4，修改完成后，当前任务数会被Aria自动调度任务数 |
|
|
|
|
|
|
|
Aria.get(this).getDownloadConfig().setMaxTaskNum(3); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 常用接口 |
|
|
|
|
|
|
|
* 停止所有任务 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this).stopAllTask(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 删除所有任务 |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
```java |
|
|
|
|
|
|
|
Aria.download(this).removeAllTask(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 获取当前任务的下载速度 |
|
|
|
|
|
|
|
速度参数有点特殊，需要[下载事件支持](#下载状态获取) |
|
|
|
|
|
|
|
``` java |
|
|
|
|
|
|
|
@Override public void onTaskRunning(DownloadTask task) { |
|
|
|
|
|
|
|
//如果你打开了速度单位转换配置，将可以通过以下方法获取带单位的下载速度，如：1 m/s |
|
|
|
|
|
|
|
String convertSpeed = task.getConvertSpeed(); |
|
|
|
|
|
|
|
//如果你有自己的单位格式，可以通过以下方法获取原始byte长度 |
|
|
|
|
|
|
|
long speed = task.getSpeed(); |
|
|
|
|
|
|
|
} |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 获取下载的文件大小、当前进度百分比 |
|
|
|
|
|
|
|
同样的，你也可以在DownloadTask对象中获取下载的文件大小 |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
@Override public void onTaskRunning(DownloadTask task) { |
|
|
|
|
|
|
|
//获取文件大小 |
|
|
|
|
|
|
|
long fileSize = task.getFileSize(); |
|
|
|
|
|
|
|
//获取单位转换后的文件大小 |
|
|
|
|
|
|
|
String fileSize1 = task.getConvertFileSize(); |
|
|
|
|
|
|
|
//当前进度百分比 |
|
|
|
|
|
|
|
int percent = task.getPercent(); |
|
|
|
|
|
|
|
} |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
* 设置高优先级任务 |
|
|
|
|
|
|
|
如果你希望优先下载某一个任务，你可以 |
|
|
|
|
|
|
|
``` java |
|
|
|
|
|
|
|
Aria.download(this).load(DOWNLOAD_URL).setDownloadPath(PATH).setHighestPriority(); |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
**tips:为了防止内存泄露的情况，事件类需要使用staic进行修饰** |

|
|
## 上传 |
|
|
|
|
|
|
|
* 添加任务(只添加，不上传) |
|
|
|
|
|
|
|
|
|

|
|
|
|
|
```java |
