用法
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {
implementation 'com.github.buhuiming:DownloadCore:1.0.2'
}
1、 初始化配置
val parentPath = context.getExternalFilesDir("downloadFiles")?.absolutePath
val downloadRequest = DownloadRequest(context)
val downloadConfig: DownloadConfig = DownloadConfig.Builder()
.setMaxDownloadSize(3)
.setWriteTimeout(30)
.setReadTimeout(30)
.setConnectTimeout(15)
.setLogger(true)
.setDownloadParentPath(parentPath)
.setDownloadOverWiFiOnly(true) //仅WiFi时下载
.setDownloadInTheBackground(null, 111111)//传空，则退出APP，停止下载；传Notification，则开启前台Service下载
.build()
downloadRequest?.newRequest(downloadConfig)
//为每一个下载 添加下载监听
downloadRequest?.registerCallback(fileName, object : DownloadObserver(context) {
override fun onInitialize(dLFModel: DownLoadFileModel) {
super.onInitialize(dLFModel)
Timber.d("onInitialize: " + dLFModel.downLoadUrl)
}
override fun onWaiting(dLFModel: DownLoadFileModel) {
super.onWaiting(dLFModel)
Timber.d("onWaiting: " + dLFModel.downLoadUrl)
}
override fun onStop(dLFModel: DownLoadFileModel) {
super.onStop(dLFModel)
Timber.d("onStop")
}
override fun onComplete(dLFModel: DownLoadFileModel) {
super.onComplete(dLFModel)
Timber.d("onComplete")
}
override fun onProgress(dLFModel: DownLoadFileModel) {
super.onProgress(dLFModel)
Timber.d("url: " + dLFModel.downLoadUrl)
Timber.d(
"totalLength: " + dLFModel.totalLength.toString() + ", totalReadBytes: " +
dLFModel.downLoadLength.toString() + ", progress: " + dLFModel.progress
)
}
override fun onFail(dLFModel: DownLoadFileModel, throwable: Throwable) {
super.onFail(dLFModel, throwable)
Timber.e("onFail" + throwable.message)
}
})
2、 添加、开始下载
downloadRequest?.startDownload(url, fileName)
3、 重新下载
downloadRequest?.reStartDownload(url, fileName)
4、 暂停下载
downloadRequest?.pauseDownload(url, fileName)
5、 删除下载(文件会被删除)
downloadRequest?.deleteDownload(url, fileName)
6、 检查下载是否完成
DownLoadUtil.checkExistFullFile(context, fileName, parentPath)
7、 检查是否存在未完成下载(0 < progress < 100)
DownLoadUtil.getExistFileProgress(context, fileName, parentPath)
8、 取消某个下载监听，关闭所有下载监听
downloadRequest?.unRegisterCallback(fileName)
downloadRequest?.close()
