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

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:1.0.0'1.

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
      }
    }
  }1.

然后在应用程序类的onStart()方法中初始化它:

PRDownloader.initialize(getApplicationContext());1.

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) {
                               
                            }
                        });            1.
