问题
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:
// Retrieve the VoiceCatalog and download the latest updates VoiceCatalog voiceCatalog = VoiceCatalog.getInstance(); voiceCatalog.downloadCatalog(new VoiceCatalog.OnDownloadDoneListener() { @Override public void onDownloadDone(VoiceCatalog.Error error) { if (error == VoiceCatalog.Error.NONE) { // catalog download successful Toast.makeText(getApplicationContext(), "Voice catalog download successful.", Toast.LENGTH_LONG).show(); } else { Toast.makeText(getApplicationContext(), "Voice catalog download error.", Toast.LENGTH_LONG).show(); } } });
onDownloadDone() function will always receive an error: VoiceCatalog.Error UNKNOW
VoiceCatalog.getInstance().isLocalCatalogAvailable()
isLocalCatalogAvailable() will always be false.
- A set of sample voice skins from sdk.zip/misc is copied to /data/app_namespace/files/voices-download
Could anyone suggest on this issue? Thanks.

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 =
VoiceCatalog.getInstance().getCatalogList();
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();
}
long id = -1;
// select
for (VoicePackage voicePackage : voicePackages) {
if (voicePackage.getMarcCode().compareToIgnoreCase("eng") == 0) {
//if (voicePackage.isTts()) // TODO: need to figure out why always return false
{
id = voicePackage.getId();
break;
}
}
}
if (!VoiceCatalog.getInstance().isLocalVoiceSkin(id)) {
final long finalId = id;
VoiceCatalog.getInstance().downloadVoice(id, new VoiceCatalog.OnDownloadDoneListener() {
@Override
public void onDownloadDone(VoiceCatalog.Error error) {
if (error == VoiceCatalog.Error.NONE) {
//voice skin download successful
if (DEBUG) Log.d(TAG, "Download voice skin successfully.");
//Toast.makeText(mActivity.getApplicationContext(), "Voice skin download successful.", Toast.LENGTH_LONG).show();
// set the voice skin for use by navigation manager
if (VoiceCatalog.getInstance().getLocalVoiceSkin(finalId) != null) {
m_navigationManager.setVoiceSkin(VoiceCatalog.getInstance().getLocalVoiceSkin(finalId));
} else {
if (DEBUG) Log.d(TAG, "Get local voice skin error.");
//Toast.makeText(mActivity.getApplicationContext(), "Navi manager set voice skin error.", Toast.LENGTH_LONG).show();
}
} else {
if (DEBUG) Log.d(TAG, "Download voice skin failed.");
//Toast.makeText(mActivity.getApplicationContext(), "Voice skin download error.", Toast.LENGTH_LONG).show();
}
}
});
} else {
// set the voice skin for use by navigation manager
if (VoiceCatalog.getInstance().getLocalVoiceSkin(id) != null) {
m_navigationManager.setVoiceSkin(VoiceCatalog.getInstance().getLocalVoiceSkin(id));
} else {
if (DEBUG) Log.d(TAG, "Get local voice skin error.");
//Toast.makeText(mActivity.getApplicationContext(), "Navi manager set voice skin error.", Toast.LENGTH_LONG).show();
}
}
}
});
}
}

It worked for me with these steps:
- Apply for 90 day trial here (should receive SDK package, appid, token and license key)
- Download and unzip HERE-sdk.zip
- Open HERE-sdk/tutorial/BasicMapSolution (I used eclipse)
- Refactor BasicMapActivity namespace to my namespace from step 1
- Update AndroidManifest.xml with appid, apptoken and license key
Update BasicMapActivity.java like this (updating com.here.jon.test with your namespace of course):
package com.here.jon.test; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.widget.Toast; import com.here.android.mpa.common.GeoCoordinate; import com.here.android.mpa.common.OnEngineInitListener; import com.here.android.mpa.guidance.VoiceCatalog; import com.here.android.mpa.guidance.VoiceCatalog.Error; import com.here.android.mpa.guidance.VoiceCatalog.OnDownloadDoneListener; import com.here.android.mpa.mapping.Map; import com.here.android.mpa.mapping.MapFragment; import com.here.jon.test.R; public class BasicMapActivity extends Activity { // map embedded in the map fragment private Map map = null; // map fragment embedded in this activity private MapFragment mapFragment = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Search for the map fragment to finish setup by calling init(). mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.mapfragment); mapFragment.init(new OnEngineInitListener() { @Override public void onEngineInitializationCompleted(OnEngineInitListener.Error error) { if (error == OnEngineInitListener.Error.NONE) { // retrieve a reference of the map from the map fragment map = mapFragment.getMap(); // Set the map center coordinate to the Vancouver region (no animation) map.setCenter(new GeoCoordinate(49.196261, -123.004773, 0.0), Map.Animation.NONE); // Set the map zoom level to the average between min and max (no animation) map.setZoomLevel((map.getMaxZoomLevel() + map.getMinZoomLevel()) / 2); downloadVoiceCatalog(); } else { System.out.println("ERROR: Cannot initialize Map Fragment"); } } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } private void downloadVoiceCatalog() { boolean result = VoiceCatalog.getInstance().downloadCatalog(new OnDownloadDoneListener(){ @Override public void onDownloadDone(Error error) { Toast.makeText(getApplicationContext(), "onDownloadDone: " + error.toString(), Toast.LENGTH_LONG).show(); }}); if (result) { Toast.makeText(this, "Successfully requested catalog", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(this, "Failed to request catalog", Toast.LENGTH_LONG).show(); } }
If you follow these steps, you should get a Toast with onDownloadDone: NONE at the end
