I'm making an app where I ask a question and the answering machine answers me depending on the question, but the problem is that the cell phone listens but it does not respond, that is, it does not talk.

I'm trying to using Cleveroad WaveInApp in my Application
https://github.com/Cleveroad/WaveInApp everything is working fine as I want but when Song Completed it also stops mediaPlayer.setOnCompletionListener(which works fine when I removed this code).
When I try to change the song it crashes.
Error :-

I don't know what happened.
Can anybody know about it.
There is already mediaPlayer.setOnCompleteListener inside VisualizerDbmHandler. So, for use it in other places you should use setInnerOnCompletionListener method to add own complete listener to VisualizerDbmHandler
Try do not recreate mediaPlayer but setup new source to it
**My conclusion is**: As you can see in source code of MediaPlayer - it will call onCompletion in cases that unhandled error appears). So, I think, because of recreating mediaPlayer in time, when you call startEqualizer ( recreate visualizerHandler and link it to visualizer view) inside the method linkTo - library call release to previous visualizerHandler and setup variable audioVisualizer to null, that provide you to calling stopRendering on null reference in case of onCompletion calling during to some error during reset/stop/release of MediaPlayer.
I have created app that detects otg cable,when otg cable is plugged in or out popup message appears that says otg connected or otg disconnected.How to make that popup appears when button on toolbar is clicked,popup message should only appear in action bar when otg cable is not connected,when it's connected it's should be hidden?

Add the following code in your code. When cable state changed, call cableStateWasChanged(boolean isConnected). This will show the popup button in your toolbar. When the button is clicked, a popup is shown and the button disappears. You can change the popup title and message depending on the cable state as you want it to be.
private boolean isCableConnected = false;
private boolean cableStateChanged = false;
private boolean popupWasShown = false;
#Override
public boolean onPrepareOptionsMenu(Menu menu){

} else if (popupWasShown) {

}

}

int id = item.getItemId();
if (id == ...) {
...
} else if (id == R.id.action_popup) {
popupWasShown = true;
invalidateOptionsMenu();
// You can change the popup title, message and buttons here
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(isCableConnected ? "Cable was connected" : "Cable was disconnected");
builder.setMessage("foo bar");
builder.setPositiveButton("OK", null);
builder.setNegativeButton(null, null);

Also I suggest you to use Handler instead of TimerTask, see this post
I am using the library barcodescanner from https://github.com/dm77/barcodescanner.
Currently the scanner displays a rectangle and a laser across the middle.

I think I need to extend a class from the library and override some of the methods in it but I'm not sure how to do this and have the overridden methods used in my scanner class.
Thank you for your time.
Add library module in a project (not as a dependency). Here is a tutorial how to add a library module in Android Studio.
Go to library module and find in ViewFinderView.java class drawLaser(Canvas canvas) method (draws the line in the middle).
This worked when the Glass in on XE12, I have opened the solution after about 2 Months and now with XE17 the menu items are not shown when tapped on the Live card, instead the live card is disappearing.
I have updated the GDK, I have changed the code to support the latest GDK sneak peek version 2 changes according to this (https://developers.google.com/glass/release-notes#xe12)
This is the code
public class MenuActivity extends Activity {
private static final String TAG = MenuActivity.class.getSimpleName();
private VisionService.VisionBinder mVisionService;
private ServiceConnection mConnection = new ServiceConnection() {
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
if (service instanceof VisionService.VisionBinder) {
mVisionService = (VisionService.VisionBinder) service;
openOptionsMenu();
}
// No need to keep the service bound.
unbindService(this);
}
#Override
public void onServiceDisconnected(ComponentName name) {
}
};
private boolean mResumed;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bindService(new Intent(this, VisionService.class), mConnection, 0);
}
#Override
protected void onResume() {
super.onResume();
mResumed = true;
openOptionsMenu();
}
#Override
protected void onPause() {
super.onPause();
mResumed = false;
}
#Override
public void openOptionsMenu() {
if (mResumed && mConnection != null) {
super.openOptionsMenu();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_send) {
mVisionService.requestWorkOrderCard();
finish();
return true;
} else if (id == R.id.action_refresh) {
mVisionService.requestTopWorkOrders();
finish();
return true;
} else if (id == R.id.action_finish) {
stopService(new Intent(this, VisionService.class));
finish();
return true;
} else {
return super.onOptionsItemSelected(item);
}
}
#Override
public void onOptionsMenuClosed(Menu menu) {
super.onOptionsMenuClosed(menu);
}
}
This is the error I am getting
.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?
And this Log(not error) too
Rebinding view with mis-matched type: com.google.glass.home.timeline.TimelineApiAdapter
It would be great if any body could help on this. Thank You
You need to change the way menu gets opened for XE 16 or 17. Below is my code that works:
public class MenuActivity extends Activity {
private boolean mAttachedToWindow;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
mAttachedToWindow = true;
openOptionsMenu();
}
#Override
public void onDetachedFromWindow() {
super.onDetachedFromWindow();
mAttachedToWindow = false;
}
#Override
public void openOptionsMenu() {
if (mAttachedToWindow) {
super.openOptionsMenu();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
...
}
public class AppService extends Service {
private static final String TAG = "AppService";
private static final String LIVE_CARD_ID = "HelloGlass";
private AppDrawer mCallback;
private LiveCard mLiveCard;
#Override
public void onCreate() {
super.onCreate();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
if (mLiveCard == null) {
mLiveCard = new LiveCard(this, LIVE_CARD_ID);
mCallback = new AppDrawer(this);
mLiveCard.setDirectRenderingEnabled(true).getSurfaceHolder().addCallback(mCallback);
Intent menuIntent = new Intent(this, MenuActivity.class);
mLiveCard.setAction(PendingIntent.getActivity(this, 0, menuIntent, 0));
mLiveCard.publish(PublishMode.REVEAL);
}
return START_STICKY;
}
...
}
Also, the GDK samples Stopwatch and Timer (https://developers.google.com/glass/samples/gdk) have menu-related code that works perfectly well.
I am using the class SpeechRecognizer by calling the method startListening when a button is pressed, but I get an error. First the callback methods onReadyForSpeech, onBeginningOfSpeech, onEndofSpeech are called (immediately) and at the end onError with the errorcode 2 "ERROR_NETWORK" is called. When I call the intent directly by using startActivityForResult, it works. But I want to get rid of the time consuming popup dialog.
I have the RECORD_AUDIO permission set.
I am not sure, but perhaps the intent want to load something from the internet. For that, I tried to add the INTERNET-Permission, but it did not work either.
Here the code:
public class MainActivity extends ActionBarActivity implements RecognitionListener
{
private SpeechRecognizer speechRecognizer;
public void onReadyForSpeech(Bundle params)
{
AddLog("onReadyForSpeech called.");
}
public void onBeginningOfSpeech()
{
AddLog("onBeginningOfSpeech called.");
}
public void onRmsChanged(float rmsdB)
{
AddLog("onRmsChanged called.");
}
public void onBufferReceived(byte[] buffer)
{
AddLog("onBufferReceived called.");
}
public void onEndOfSpeech()
{
AddLog("onEndOfSpeech called.");
}
public void onError(int error)
{
AddLog(String.format("onError called with id: %d.", error));
}
public void onResults(Bundle results)
{
String str = new String();
ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for(int i = 0; i < data.size(); i++)
{
str += data.get(i);
}
final String strAnswer = str;
AddLog(String.format("Answer is %s", strAnswer));
}
public void onPartialResults(Bundle psrtialResults)
{
AddLog("onPartialResults called.");
}
public void onEvent(int eventType, Bundle params)
{
AddLog("onEvent called.");
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
speechRecognizer.setRecognitionListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

#Override

{
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
AddLog(matches.get(0));
}
super.onActivityResult(requestCode, resultCode, data);
}
public void Start(View view)
{
AddLog("Start pressed.");
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getPackageName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
// Only for test
//startActivityForResult(intent, 1);
speechRecognizer.startListening(intent);
AddLog("startListening called.");
}
}
I solved it by myself. The problem was, that the language pack for US had an update. I had to load it by hand (in the language settings of my mobile). After that the error ERROR_NETWORK disappeared.
