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)

7、 取消某个下载监听，关闭所有下载监听

    downloadRequest?.unRegisterCallback(fileName)

    downloadRequest?.close()

7、 更多请参考Demo
