Android OkDownload的使用

一、前言：

OkDownload是一个android下载框架，是FileDownloader的升级版本，也称FileDownloader2；是一个支持多线程，多任务，断点续传，可靠，灵活，高性能以及强大的下载引擎。

• 结合OkGo的request进行网络请求，支持与OkGo保持相同的配置方法和传参方式
• 支持断点下载，支持突然断网，强杀进程后，继续断点下载
• 每个下载任务具有无状态、下载、暂停、等待、出错、完成共六种状态
• 所有下载任务按照tag区分，切记不同的任务必须使用不一样的tag，否者断点会发生错乱
• 相同的下载url地址，如果使用不一样的tag，也会认为是两个下载任务
• 不同的下载url地址，如果使用相同的tag，会认为是同一个任务，导致断点错乱
• 默认同时下载数量为3个，默认下载路径/storage/emulated/0/download，下载路径和下载数量都可以在代码中配置
• 下载文件名可以自己定义，也可以不传，让框架自动获取文件名

二、使用：

1、依赖

仓库依赖：

repositories {
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

jar包依赖：

// okdownload核心库
implementation 'com.liulishuo.okdownload:okdownload:1.0.5'
//存储断点信息的数据库
implementation 'com.liulishuo.okdownload:sqlite:1.0.5' 
//提供okhttp连接，如果使用的话，需要引入okhttp网络请求库
implementation 'com.liulishuo.okdownload:okhttp:1.0.5'
implementation 'com.squareup.okhttp3:okhttp:3.10.0'

2、全局控制

OkDownload.with().setMonitor(monitor);
DownloadDispatcher.setMaxParallelRunningCount(3); //最大并行下载数
RemitStoreOnSQLite.setRemitToDBDelayMillis(3000);
OkDownload.with().downloadDispatcher().cancelAll();
OkDownload.with().breakpointStore().remove(taskId);

3、组件注入

OkDownload.Builder builder = new OkDownload.Builder(context)
        .downloadStore(downloadStore)
        .callbackDispatcher(callbackDispatcher)
        .downloadDispatcher(downloadDispatcher)
        .connectionFactory(connectionFactory)
        .outputStreamFactory(outputStreamFactory)
        .downloadStrategy(downloadStrategy)
        .processFileStrategy(processFileStrategy)
        .monitor(monitor);

OkDownload.setSingletonInstance(builder.build());

4、动态串行队列

DownloadSerialQueue serialQueue = new DownloadSerialQueue(commonListener);

serialQueue.enqueue(task1);
serialQueue.enqueue(task2);

serialQueue.pause();

serialQueue.resume();

int workingTaskId = serialQueue.getWorkingTaskId();
int waitingTaskCount = serialQueue.getWaitingTaskCount();

DownloadTask[] discardTasks = serialQueue.shutdown();

4、合并几个下载的侦听器

DownloadListener listener1 = new DownloadListener1();
DownloadListener listener2 = new DownloadListener2();

DownloadListener combinedListener = new DownloadListenerBunch.Builder()
                   .append(listener1)
                   .append(listener2)
                   .build();

DownloadTask task = new DownloadTask.build(url, file).build();
task.enqueue(combinedListener);

5、任务的动态更改侦听器

// all attach or detach is based on the id of Task in fact. 
UnifiedListenerManager manager = new UnifiedListenerManager();

DownloadListener listener1 = new DownloadListener1();
DownloadListener listener2 = new DownloadListener2();
DownloadListener listener3 = new DownloadListener3();
DownloadListener listener4 = new DownloadListener4();

DownloadTask task = new DownloadTask.build(url, file).build();

manager.attachListener(task, listener1);
manager.attachListener(task, listener2);

manager.detachListener(task, listener2);

// all listeners added for this task will be removed when task is end.
manager.addAutoRemoveListenersWhenTaskEnd(task.getId());

// enqueue task to start.
manager.enqueueTaskWithUnifiedListener(task, listener3);

manager.attachListener(task, listener4);

5、为任务配置特殊配置文件

DownloadTask.Builder builder = new DownloadTask.Builder(url, file);

// Set the minimum internal milliseconds of progress callbacks to 100ms.(default is 3000)
builder.setMinIntervalMillisCallbackProcess(100);

// set the priority of the task to 10, higher means less time to wait to download.(default is 0)
builder.setPriority(10);

// set the read buffer to 8192 bytes for the response input-stream.(default is 4096)
builder.setReadBufferSize(8192);

// set the flush buffer to 32768 bytes for the buffered output-stream.(default is 16384)
builder.setFlushBufferSize(32768);

// set this task allow using 5 connections to download data.
builder.setConnectionCount(5);

// build the task.
DownloadTask task = builder.build();

三、具体属性介绍：

1、 使用

DownloadTask task = new DownloadTask.Builder(url, parentFile)
         .setFilename(filename) 
         .setMinIntervalMillisCallbackProcess(30) // 下载进度回调的间隔时间（毫秒）
         .setPassIfAlreadyCompleted(false)// 任务过去已完成是否要重新下载
         .setPriority(10)
         .build();
task.enqueue(listener);//异步执行任务
task.cancel();// 取消任务
task.execute(listener);// 同步执行任务
DownloadTask.enqueue(tasks, listener); //同时异步执行多个任务

2、 配置 DownloadTask

• setPreAllocateLength(boolean preAllocateLength) //在获取资源长度后，设置是否需要为文件预分配长度
• setConnectionCount(@IntRange(from = 1) int connectionCount) //需要用几个线程来下载文件
• setFilenameFromResponse(@Nullable Boolean filenameFromResponse)//如果没有提供文件名，是否使用服务器地址作为的文件名
• setAutoCallbackToUIThread(boolean autoCallbackToUIThread) //是否在主线程通知调用者
• setMinIntervalMillisCallbackProcess(int minIntervalMillisCallbackProcess) //通知调用者的频率，避免anr
• setHeaderMapFields(Map headerMapFields)//设置请求头
• addHeader(String key, String value)//追加请求头
• setPriority(int priority)//设置优先级，默认值是0，值越大下载优先级越高
• setReadBufferSize(int readBufferSize)//设置读取缓存区大小，默认4096
• setFlushBufferSize(int flushBufferSize)//设置写入缓存区大小，默认16384
• setSyncBufferSize(int syncBufferSize)//写入到文件的缓冲区大小，默认65536
• setSyncBufferIntervalMillis(int syncBufferIntervalMillis)//写入文件的最小时间间隔
• setFilename(String filename)//设置下载文件名
• setPassIfAlreadyCompleted(boolean passIfAlreadyCompleted)//如果文件已经下载完成，再次发起下载请求时，是否忽略下载，还是从头开始下载
• setWifiRequired(boolean wifiRequired)//只允许wifi下载

案例

private DownloadTask createDownloadTask(ItemInfo itemInfo) {
    return new DownloadTask.Builder(itemInfo.url, new File(Utils.PARENT_PATH)) //设置下载地址和下载目录，这两个是必须的参数
        .setFilename(itemInfo.pkgName)//设置下载文件名，没提供的话先看 response header ，再看 url path(即启用下面那项配置)
        .setFilenameFromResponse(false)//是否使用 response header or url path 作为文件名，此时会忽略指定的文件名，默认false
        .setPassIfAlreadyCompleted(true)//如果文件已经下载完成，再次下载时，是否忽略下载，默认为true(忽略)，设为false会从头下载
        .setConnectionCount(1)  //需要用几个线程来下载文件，默认根据文件大小确定；如果文件已经 split block，则设置后无效
        .setPreAllocateLength(false) //在获取资源长度后，设置是否需要为文件预分配长度，默认false
        .setMinIntervalMillisCallbackProcess(100) //通知调用者的频率，避免anr，默认3000
        .setWifiRequired(false)//是否只允许wifi下载，默认为false
        .setAutoCallbackToUIThread(true) //是否在主线程通知调用者，默认为true
        //.setHeaderMapFields(new HashMap>())//设置请求头
        //.addHeader(String key, String value)//追加请求头
        .setPriority(0)//设置优先级，默认值是0，值越大下载优先级越高
        .setReadBufferSize(4096)//设置读取缓存区大小，默认4096
        .setFlushBufferSize(16384)//设置写入缓存区大小，默认16384
        .setSyncBufferSize(65536)//写入到文件的缓冲区大小，默认65536
        .setSyncBufferIntervalMillis(2000) //写入文件的最小时间间隔，默认2000
        .build();
}

3、任务队列的构建、开始和停止

DownloadContext.Builder builder = new DownloadContext.QueueSet()
        .setParentPathFile(parentFile)
        .setMinIntervalMillisCallbackProcess(150)
        .commit();
builder.bind(url1);
builder.bind(url2).addTag(key, value);
builder.bind(url3).setTag(tag);
builder.setListener(contextListener);

DownloadTask task = new DownloadTask.Builder(url4, parentFile).build();
builder.bindSetTask(task);

DownloadContext context = builder.build();
context.startOnParallel(listener);
context.stop();

4、获取任务状态

Status status = StatusUtil.getStatus(task);
Status status = StatusUtil.getStatus(url, parentPath, null);
Status status = StatusUtil.getStatus(url, parentPath, filename);

boolean isCompleted = StatusUtil.isCompleted(task);
boolean isCompleted = StatusUtil.isCompleted(url, parentPath, null);
boolean isCompleted = StatusUtil.isCompleted(url, parentPath, filename);

Status completedOrUnknown = StatusUtil.isCompletedOrUnknown(task);

四、使用：

1、必要的配置：

1、申请两个权限：WRITE_EXTERNAL_STORAGE 和 REQUEST_INSTALL_PACKAGES
2、配置 FileProvider
3、添加依赖

2、Activity

public class DownloadActivity extends ListActivity {
    static final String URL1 = "https://oatest.dgcb.com.cn:62443/mstep/installpkg/yidongyingxiao/90.0/DGMmarket_rtx.apk";
    static final String URL2 = "https://cdn.llscdn.com/yy/files/xs8qmxn8-lls-LLS-5.8-800-20171207-111607.apk";
    static final String URL3 = "https://downapp.baidu.com/appsearch/AndroidPhone/1.0.78.155/1/1012271b/20190404124002/appsearch_AndroidPhone_1-0-78-155_1012271b.apk";

4、 辅助Bean

public class ItemInfo {
    String url;
    String pkgName; //包名
    int status;  // 0：没有下载 1：下载中 2：暂停 3：完成

    public ItemInfo(String url, String pkgName) {
        this.url = url;
        this.pkgName = pkgName;
    }
}

5、DownloadListener4WithSpeed

public class MyDownloadListener4WithSpeed extends DownloadListener4WithSpeed {
    private ItemInfo itemInfo;
    private long totalLength;
    private String readableTotalLength;
    private ProgressBar progressBar;//谨防内存泄漏
    private Context context;//谨防内存泄漏

    public MyDownloadListener4WithSpeed(ItemInfo itemInfo, ProgressBar progressBar) {
        this.itemInfo = itemInfo;
        this.progressBar = progressBar;
        context = progressBar.getContext();
    }

    @Override
    public void taskStart(@NonNull DownloadTask task) {
        Log.i("bqt", "【1、taskStart】");
    }

    @Override
    public void infoReady(@NonNull DownloadTask task, @NonNull BreakpointInfo info, boolean fromBreakpoint, @NonNull Listener4SpeedAssistExtend.Listener4SpeedModel model) {
        totalLength = info.getTotalLength();
        readableTotalLength = Util.humanReadableBytes(totalLength, true);
        Log.i("bqt", "【2、infoReady】当前进度" + (float) info.getTotalOffset() / totalLength * 100 + "%" + "，" + info.toString());
        progressBar.setMax((int) totalLength);
    }

    @Override
    public void connectStart(@NonNull DownloadTask task, int blockIndex, @NonNull Map> requestHeaders) {
        Log.i("bqt", "【3、connectStart】" + blockIndex);
    }

    @Override
    public void connectEnd(@NonNull DownloadTask task, int blockIndex, int responseCode, @NonNull Map> responseHeaders) {
        Log.i("bqt", "【4、connectEnd】" + blockIndex + "，" + responseCode);
    }

    @Override
    public void progressBlock(@NonNull DownloadTask task, int blockIndex, long currentBlockOffset, @NonNull SpeedCalculator blockSpeed) {
        //Log.i("bqt", "【5、progressBlock】" + blockIndex + "，" + currentBlockOffset);
    }

    @Override
    public void progress(@NonNull DownloadTask task, long currentOffset, @NonNull SpeedCalculator taskSpeed) {
        String readableOffset = Util.humanReadableBytes(currentOffset, true);
        String progressStatus = readableOffset + "/" + readableTotalLength;
        String speed = taskSpeed.speed();
        float percent = (float) currentOffset / totalLength * 100;
        Log.i("bqt", "【6、progress】" + currentOffset + "[" + progressStatus + "]，速度：" + speed + "，进度：" + percent + "%");
        progressBar.setProgress((int) currentOffset);
    }

    @Override
    public void blockEnd(@NonNull DownloadTask task, int blockIndex, BlockInfo info, @NonNull SpeedCalculator blockSpeed) {
        Log.i("bqt", "【7、blockEnd】" + blockIndex);
    }

    @Override
    public void taskEnd(@NonNull DownloadTask task, @NonNull EndCause cause, @Nullable Exception realCause, @NonNull SpeedCalculator taskSpeed) {
        Log.i("bqt", "【8、taskEnd】" + cause.name() + "：" + (realCause != null ? realCause.getMessage() : "无异常"));
        Utils.dealEnd(context, itemInfo, cause);
    }
}
