环信 下载语音文件

调用后台获取环信历史记录

 "type": "audio"语音类型数据倒是拿到了，但是怎么去播放，环信并没有提供直接播放的api，

然后就参考环信是如果下载图片的方式来下载语音文件，最后去播放。

以下是点击语音图标播放的事件：

holder.iv.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        final HttpFileManager httpFileMgr = new HttpFileManager(context,
                EMChatConfig.getInstance().getStorageUrl());
        remoteFilePath = resultEntity.getUrl();
        String secret = resultEntity.getSecret();

//构建下载map
        final Map<String, String> maps = new HashMap<String, String>();
        String accessToken = EMChatManager.getInstance().getAccessToken();
        maps.put("Authorization", "Bearer " + accessToken);
        if (!TextUtils.isEmpty(secret)) {
            maps.put("share-secret", secret);
        }
        maps.put("Accept", "application/octet-stream");


        if (remoteFilePath.contains("/"))
            localFilePath = PathUtil.getInstance().getVoicePath()
                    .getAbsolutePath()
                    + "/"
                    + remoteFilePath.substring(remoteFilePath
                    .lastIndexOf("/") + 1);
        else
            localFilePath = PathUtil.getInstance().getVoicePath()
                    .getAbsolutePath()
                    + "/" + remoteFilePath;
        if ((new File(localFilePath).exists())) {
//已经下载，直接播放
            playVoice(localFilePath,holder.iv,resultEntity);
            return;
        }

        new Thread(new Runnable() {
            @Override
            public void run() {
                httpFileMgr.downloadFile(remoteFilePath, localFilePath,
                        EMChatConfig.getInstance().APPKEY, maps, new CloudOperationCallback() {
                            @Override
                            public void onSuccess(String s) {
                                //下载成功，播放
                                playVoice(localFilePath,holder.iv,resultEntity);

                            }

                            @Override
                            public void onError(String s) {

                            }

                            @Override
                            public void onProgress(int i) {

                            }
                        });
            }
        }).start();

    }
});
