SimpleDownload 2 | 3 | kotlin协程+channel实现下载，支持多任务下载、断点续传 4 | 5 | ## 添加依赖库 6 | 7 | - 项目build.gradle 8 | 9 | ``` 10 | allprojects { 11 | repositories { 12 | ... 13 | maven { url 'https://jitpack.io' } 14 | } 15 | } 16 | ``` 17 | 18 | - 添加依赖 19 | 20 | ``` 21 | dependencies { 22 | implementation 'com.github.LetMeOff:SimpleDownload:v1.0.0' 23 | } 24 | ``` 25 | 26 | ## 使用 27 | 28 | 1. Application中初始化 29 | 30 | ``` 31 | SimpleDownload.instance.init(this) 32 | ``` 33 | 34 | 2. 简单使用 35 | 36 | ```kotlin 37 | //创建下载任务 38 | val downloadTask = scope.download(downloadUrl) 39 | 40 | //状态监听 41 | downloadTask.state().onEach { 42 | when (it) { 43 | is State.None -> logD("未开始任务") 44 | is State.Waiting -> logD("等待中") 45 | is State.Downloading -> logD("下载中") 46 | is State.Failed -> logD("下载失败") 47 | is State.Stopped -> logD("下载已暂停") 48 | is State.Succeed -> logD("下载成功") 49 | } 50 | logD("state : $it") 51 | }.launchIn(scope) 52 | 53 | //进度监听 54 | downloadTask.progress().onEach { 55 | logD("name : $saveName , progress : ${it.percentStr()}") 56 | }.launchIn(scope) 57 | 58 | //开始下载任务 59 | downloadTask.start() 60 | ``` 61 | 62 | ## 创建任务 63 | 64 | - 可以在指定的协程中调用***download***方法开始任务，任务的生命周期取决于协程的生命周期。如： 65 | 66 | ```kotlin 67 | val downloadTask = lifecycleScope.download(downloadUrl) 68 | ``` 69 | 70 | 此下载任务会在***Activity***销毁后结束 71 | 72 | - 默认保存名会从下载链接中获取，默认保存路径为```/data/data/包名/files```下，可以自定义 73 | 74 | ```kotlin 75 | val downloadTask = scope.download(downloadUrl, saveName, savePath) 76 | ``` 77 | 78 | 或者自定义参数 79 | 80 | ```kotlin 81 | //自定义参数 82 | val params = DownloadParam(downloadUrl, saveName, savePath) 83 | val config = DownloadConfig() 84 | config.baseUrl = "http://www.example.com" 85 | val downloadTask = scope.download(params, config) 86 | ``` 87 | 88 | - 下载任务默认使用下载链接作为唯一标识，可以自定义 89 | 90 | ```kotlin 91 | class CustomDownloadParam(url: String, saveName: String, savePath: String) : 92 | DownloadParam(url, saveName, savePath) { 93 | override fun tag(): String { 94 | //定义唯一标示 95 | return savePath + saveName 96 | } 97 | } 98 | 99 | //使用 100 | val customParams = CustomDownloadParam(downloadUrl, saveName, savePath) 101 | val downloadTask = scope.download(customParams) 102 | ``` 103 | 104 | - 在多个页面使用同样的标识创建任务时，将会返回同一个任务，因此可以在不同界面监听同一任务的进度和状态 105 | 106 | ## 状态和进度 107 | 108 | 通过```launchIn(scope)```指定监听所在的协程，以便于销毁监听 109 | 110 | - 状态监听 111 | 112 | ```kotlin 113 | //状态监听 114 | downloadTask.state().onEach { 115 | when (it) { 116 | is State.None -> logD("未开始任务") 117 | is State.Waiting -> logD("等待中") 118 | is State.Downloading -> logD("下载中") 119 | is State.Failed -> logD("下载失败") 120 | is State.Stopped -> logD("下载已暂停") 121 | is State.Succeed -> logD("下载成功") 122 | } 123 | logD("state : $it") 124 | }.launchIn(scope) 125 | ``` 126 | 127 | - 进度监听 128 | 129 | ```kotlin 130 | //进度监听 131 | downloadTask.progress().onEach { 132 | logD("name : $saveName , progress : ${it.percentStr()}") 133 | }.launchIn(scope) 134 | ``` 135 | 136 | 可以自定义监听间隔时间```downloadTask.state(500)```，```downloadTask.progress(500)```，默认200ms 137 | 138 | ## 任务操作 139 | 140 | - 开始 141 | 142 | ```kotlin 143 | downloadTask.start() 144 | ``` 145 | 146 | - 停止 147 | 148 | ```kotlin 149 | downloadTask.stop() 150 | ``` 151 | 152 | - 删除（true : 删除文件，false : 不删除，默认false） 153 | 154 | ```kotlin 155 | downloadTask.remove() 156 | ``` -------------------------------------------------------------------------------- /app/.gitignore:
