语音目录在本地存储中不可用，用于“此处映射语音指令"功能

问题描述

按照此处的导航语音指令的Android SDK开发人员指南中的步骤操作，我无法启动语音功能.调试信息如下:

Following the steps in HERE Android SDK Developer's Guide for Navigation Voice Instruction, I cannot start the Voice feature. The debug information is as below:

1. //检索VoiceCatalog并下载最新更新VoiceCatalog voiceCatalog = VoiceCatalog.getInstance();voiceCatalog.downloadCatalog(新的VoiceCatalog.OnDownloadDoneListener(){@Override公共无效onDownloadDone(VoiceCatalog.Error错误){如果(错误== VoiceCatalog.Error.NONE){//目录下载成功Toast.makeText(getApplicationContext()，语音目录下载成功."，Toast.LENGTH_LONG).show();} 别的 {Toast.makeText(getApplicationContext()，语音目录下载错误."，Toast.LENGTH_LONG).show();}}});

onDownloadDone()函数将始终收到错误: VoiceCatalog.Error UNKNOW

onDownloadDone() function will always receive an error: VoiceCatalog.Error UNKNOW

1. VoiceCatalog.getInstance().isLocalCatalogAvailable()

isLocalCatalogAvailable()始终为false.

1. 将sdk.zip/misc中的一组示例语音皮肤复制到/data/app_namespace/files/voices-download

有人可以建议这个问题吗?谢谢.

Could anyone suggest on this issue? Thanks.

针对此问题，我们找到了以下解决方案.

We find the following solution for this issue.

     private void setupVoice() {
        // Retrieve the VoiceCatalog and download the latest updates
        VoiceCatalog voiceCatalog = VoiceCatalog.getInstance();

        if (!voiceCatalog.isLocalCatalogAvailable()) {
            if (DEBUG) Log.d(TAG, "Voice catalog is not available in local storage.");
            //Toast.makeText(mActivity.getApplicationContext(), "Voice catalog is not available in local storage.", Toast.LENGTH_LONG).show();

            voiceCatalog.downloadCatalog(new VoiceCatalog.OnDownloadDoneListener() {
                @Override
                public void onDownloadDone(VoiceCatalog.Error error) {
                    if (error == VoiceCatalog.Error.NONE) {
                        // catalog download successful
                        if (DEBUG) Log.d(TAG, "Download voice catalog successfully.");

                        //Toast.makeText(mActivity.getApplicationContext(), "Voice catalog download successful.", Toast.LENGTH_LONG).show();
                    } else {
                        if (DEBUG) Log.d(TAG, "Download voice catalog failed.");

                        //Toast.makeText(mActivity.getApplicationContext(), "Voice catalog download error.", Toast.LENGTH_LONG).show();

                    // Get the list of voice packages from the voice catalog list
                    List<VoicePackage> voicePackages =

                    if (voicePackages.size() == 0) {
                        if (DEBUG) Log.d(TAG, "Voice catalog size is 0.");

                        //Toast.makeText(mActivity.getApplicationContext(), "Voice catalog size is 0.", Toast.LENGTH_LONG).show();
