效果演示

鸿蒙开源组件——一个文件下载库-开源基础软件社区

安装教程

在moudle级别下的build.gradle文件中添加依赖

// 添加maven仓库
repositories {
   maven {
       url 'https://s01.oss.sonatype.org/content/repositories/releases/'
   }
}

// 添加依赖库
dependencies {
   implementation 'com.gitee.chinasoft_ohos:prdownloader:1.0.0'
}

在sdk6,DevEco Studio2.2 beta1下项目可直接运行 如无法运行,删除项目.gradle,.idea,build,gradle,build.gradle文件, 并依据自己的版本创建新项目,将新项目的对应文件复制到根目录下

使用说明

一个文件下载库的openharmony与暂停和恢复支持

Add this in your build.gradle

implementation 'com.gitee.chinasoft_ohos:prdownloader:1.0.0'

如果已经不存在,不要忘记在config.json中添加互联网许可

 "deviceConfig": {
    "default": {
      "network": {
        "usesCleartext": true
      }
    }
  }

然后在应用程序类的onStart()方法中初始化它:

PRDownloader.initialize(getApplicationContext());

用一些定制来初始化它

// Enabling database for resume support even after the application is killed:
PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
                .setDatabaseEnabled(true)
                .build();
PRDownloader.initialize(getApplicationContext(), config);

// Setting timeout globally for the download network requests:
PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
                .setReadTimeout(30_000)
                .setConnectTimeout(30_000)
                .build();
PRDownloader.initialize(getApplicationContext(), config); 
  • 发送一个下载请求
    int downloadId = PRDownloader.download(url, dirPath, fileName) .build() .setOnStartOrResumeListener(new OnStartOrResumeListener() { @Override public void onStartOrResume() { } }) .setOnPauseListener(new OnPauseListener() { @Override public void onPause() { } }) .setOnCancelListener(new OnCancelListener() { @Override public void onCancel() { } }) .setOnProgressListener(new OnProgressListener() { @Override public void onProgress(Progress progress) { } }) .start(new OnDownloadListener() { @Override public void onDownloadComplete() { } @Override public void onError(Error error) { } }); ​
  • 暂停一个下载请求
    PRDownloader.pause(downloadId);​
  • 重新继续一个下载请求
    PRDownloader.resume(downloadId);​
  • 退出一个下载请求
    // Cancel with the download id PRDownloader.cancel(downloadId); // The tag can be set to any request and then can be used to cancel the request PRDownloader.cancel(TAG); // Cancel all the requests PRDownloader.cancelAll();​
  • 下载状态获取
    Status status = PRDownloader.getStatus(downloadId);​
  • 如果启用了数据库,清理恢复的文件
    // Method to clean up temporary resumed files which is older than the given day PRDownloader.cleanUp(days);​
  • TODO *与其他库如OkHttp, RxJava集成 *测试用例 *当然还有许多功能和bug修复
