Question

@Override
public void run() {
    try {

        downloadTaskObserver.onPendingStarted();

        File dir = new File(Environment.getExternalStorageDirectory(), RMConfig.RM_FOLDER);
        dir.mkdirs();
        String sFileName = dir + "/" + trackInfo.getTrackMetadata().getTrackId() + ".mp3";
        File root = new File(sFileName);

        if (!root.exists()) {
            root.createNewFile();
        } else {
            return;
        }

        HttpGet mHttpGet = new HttpGet(trackInfo.getMediaUrl());
        HttpResponse response = WSManager.getInstalnce().getRHHttpsClient().execute(mHttpGet);
        InputStream zipStream = response.getEntity().getContent();
        FileOutputStream fOut = new FileOutputStream(root);

        long fileSize = Long.valueOf(response.getFirstHeader("Content-Length").getValue());

        long byteCount = 0;
        byte[] buffer = new byte[4096];
        int bytesRead = -1;

        downloadTaskObserver.onDownloadStarted();

        while ((bytesRead = zipStream.read(buffer)) != -1 && !cancelDownload) {
            fOut.write(buffer, 0, bytesRead);
            byteCount += bytesRead;

            int value = (int) (byteCount * 100L / fileSize);
            downloadTaskObserver.onUpdateProgress(value);
        }
        if (fOut != null) {
            fOut.flush();
            fOut.close();
        }
        if (zipStream != null) {
            zipStream.close();
        }

        if (!cancelDownload) {
            downloadTaskObserver.onDownloadFinished();
        }

    } catch (Exception e) {
        e.printStackTrace();

        downloadTaskObserver.onDownloadError();
    }
}


public interface DownloadTaskObserver {
    public void onPendingStarted();
    public void onDownloadStarted();
    public void onDownloadFinished();
    public void onDownloadCanceled();
    public void onUpdateProgress(int percent);
    public void onDownloadError();
}



public void addToDownloadQueue(GetTrackPlaybackInfo trackInfo, DownloadTaskObserver downloadTaskObserver) {
        DownloadTask downloadTask = new DownloadTask(trackInfo, downloadTaskObserver);
        mDownloadTasks.add(downloadTask);
//      mDownloadTasksPool.execute(downloadTask);
        new Thread(downloadTask).start();
    }

但是每当我开始下载另一个线程时，它似乎就完成了。我没看到什么可能是错的？提前感谢您的帮助。

Answer 1

HttpResponse response = WSManager.getInstalnce().getRHHttpsClient().execute(mHttpGet);

getRHHttpsClient（）每次都会为您提供一个新客户端，还是旧的客户端回收？

下一个下载线程中断前一个：为什么？
