Develop Reference

SpeechRecognizer will be repeated, instead of running permanently

I'm trying to develop something similar to Google Assistant. So when I say "OK app", it should handle. So I have just created a service that is running in the background:
public class SttService extends Service implements RecognitionListener {
private static final String TAG = "SstService";
SpeechRecognizer mSpeech;
private void speak() {
mSpeech = SpeechRecognizer.createSpeechRecognizer(SttService.this);
mSpeech.setRecognitionListener(SttService.this);
Intent intent1 = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent1.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
mSpeech.startListening(intent1);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand: I am running");
speak();
return START_STICKY;
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
Log.e(TAG, "onBind: ");
return null;
}
#Override
public void onReadyForSpeech(Bundle params) {
Log.e(TAG, "onReadyForSpeech: ");
}
#Override
public void onBeginningOfSpeech() {
Log.e(TAG, "onBeginningOfSpeech: ");
}
#Override
public void onRmsChanged(float rmsdB) {
// Log.e(TAG, "onRmsChanged: ");
}
#Override
public void onBufferReceived(byte[] buffer) {
Log.e(TAG, "onBufferReceived: ");
}
#Override
public void onEndOfSpeech() {
Log.e(TAG, "onEndOfSpeech: ");
}
#Override
public void onError(int error) {
Log.e(TAG, "onError: " + error);
if (error == 7) {
speak();
}
}
#Override
public void onResults(Bundle results) {
ArrayList<String> resultsStringArrayList = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
String mainResult = resultsStringArrayList.get(0);
Log.e(TAG, "onResults: " + mainResult);
if (mainResult.equalsIgnoreCase("Okay App")) {
System.out.println("What's up?");
}
mSpeech.destroy();
mSpeech = null;
speak();
}
#Override
public void onPartialResults(Bundle partialResults) {
Log.e(TAG, "onPartialResults: ");
}
#Override
public void onEvent(int eventType, Bundle params) {
Log.e(TAG, "onEvent: ");
}
}
My problem is that the app is not listening permanently. It starts listening and then there is a result. When I don't say anything, it will be listening for about 2 seconds, then SpeechRecognizer will be destroyed, so another speech can begin. So in the time when it is getting destroyed, there is a break and when I say something in the meantime, it will not be recognized.
My app is not doing what I want. Probably I am doing it completely the wrong way. So what I am trying to achieve is a SpeechRecognizer that runs permanently and only handles when I say "Okay App". How can I do this?

That's how SpeechRecognizer is designed. It's not meant for permanent background listening, it's meant for short term immediate responses. Like when someone hits the mic button in the search bar. If you want permanent background listening, you're going to have to go lower level and do it yourself.

Using DJI Android SDK LiveStreamManager to stream drone camera live has a huge delay. Using the SampleCode it doesn't, what am I missing?

I have created an android application using the DJI SDK. I have followed the instruction, and basically copied the code from the DJI Sample Code (https://github.com/dji-sdk/Mobile-SDK-Android/blob/master/Sample%20Code/app/src/main/java/com/dji/sdk/sample/demo/camera/LiveStreamView.java), since it was working properly.
After launching a Connectivity activity, which registers the SDK and connects to the Mavic 2 Zoom drone, another activity comes, which handles live streaming to a RTMP server. When using the sample code, streaming to the same RTMP server, it has no delay, but when using my app, it has a good 15 second delay. I can't figure out why, I'm using the same components. The only difference is that I'm setting the camera focus to the max, but I did the same in the Sample Code, so it shouldn't cause any problems. Also using the same VideoFeedView as in the Sample.

private static final String TAG = MainActivity.class.getName();

Any idea why? I have tested it on Google Pixel 2, and Huawei Mate 10. The sample has no problem on both devices, my app has the delay. Thanks!

Answering my own question, the only difference I noticed was that the SampleCode asked for 4 permission, and all the projects I've tried or copied the permissions, always just 3 permissions.
So Manifest:
< uses-permission android:name="android.permission.RECORD_AUDIO" />
your runtime permissions:
Manifest.permission.RECORD_AUDIO
and the delay is gone, all works fine. Still don't know why :)

Displaying only service name NSD network service discovery Android

I have this question again about NSD, this time I would like to ask ask if anybody know how to display only service name without all the details like port, host, service type.So far I managed to display all services using ArrayList and NsdServiceInfo object which displays all details about service as I mentioned before, but in my case I want to display only service name.
If you have any ideas, you are more than welcome to share with me

I want to show a loading animation while connecting to a websocket

I'm trying to show an animation in my app while connecting to a web server, just so that the user doesn't think that it's crashed/frozen.
Here's the bit in the code that may be relevant:
private void waitForWebSocketConnect() {
long start = System.currentTimeMillis();
long end = start + 3*1000; // 3 seconds
while (!mWebSocketClient.isOpen()) {
try {
Thread.sleep(200);
if(System.currentTimeMillis() >= end){
throw new InterruptedException();
}
} catch (InterruptedException e) {
fatalError("WebSocket did not connect. Please try again.");
}
}
}
I think this might also be of use:
private void connectWebSocket() {
final Activity faActivity = super.getActivity();
URI uri;
try {
String uriString;
if(isRegistering){
//uriString = "ws://app.touchtechpayments.com:80/reg";
uriString = "wss://ec2-52-16-13-241.eu-west-1.compute.amazonaws.com/reg";
} else {
//uriString = "ws://app.touchtechpayments.com:80/trans";
uriString = "wss://ec2-52-16-13-241.eu-west-1.compute.amazonaws.com/trans";
}
Log.d("uriString", uriString);
uri = new URI(uriString);
} catch (URISyntaxException e) {
e.printStackTrace();
return;
}
mWebSocketClient = new WebSocketClient(uri) {
#Override
public void onOpen(ServerHandshake serverHandshake) {
this.progressBar.setVisibility(View.GONE);
Log.d("Websocket", "Opened");
}
#Override
public void onMessage(String s) {
Log.d("Websocket", "Received message " + s);
if(isRegistering) {
confirmRegistration(s);
} else {
confirmTransaction(s);
}
}
#Override
public void onClose(int i, String s, boolean b) {
Log.d("Websocket", "Closed " + s);
if(!allDone) {
if (triedTwice) {
final String printToast = "Error received: " + s + "\nPlease try again.";
faActivity.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(context, printToast, Toast.LENGTH_LONG).show();
faActivity.getFragmentManager().popBackStack();
}
});
} else {
Log.d("Websocket", "Trying for second time.");
triedTwice = true;
if (lastInputToServer != null) {
setupSSL();
connectWebSocket();
waitForWebSocketConnect();
mWebSocketClient.send(lastInputToServer);
}
}
}
}
#Override
public void onError(Exception e) {
this.progressBar.setVisibility(View.GONE);
Log.d("Websocket", "Error " + e.getMessage());
}
};
setupSSL();
mProgressBar.setVisibility(View.VISIBLE);
mWebSocketClient.connect();
}
The webSocketClient isn't actually defined in onCreate(), but the above method IS used in onCreate() anyway.

First define a ProgressBar in your layout.xml and enable the indeterminate mode by using indeterminate parameter:
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible"
android:indeterminate = "true"/>
Then hide your progressBar as soon as the websocket connection has been established:
public void onCreate(){
[...]
mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
mWebSocketClient = new WebSocketClient(uri) {
#Override
public void onOpen(ServerHandshake serverHandshake){
this.progressBar.setVisibility(View.GONE); // or INVISIBLE
}
#Override
public void onMessage(String s) {
}
#Override
public void onClose(int i, String s, boolean b) {
}
#Override
public void onError(Exception e) {
this.progressBar.setVisibility(View.GONE); // or INVISIBLE
}
};
mProgressBar.setVisibility(View.VISIBLE);
mWebSocketClient.connect();
}
You can also define your ProgressBar as invisible and show it later before mWebSocketClient.connect() call.
P.S. I'm using this java websocket library in this example
dependencies {
compile "org.java-websocket:Java-WebSocket:1.3.0"
}

you can use j Progress bar in the program simultaneously with timer so it will be ok for the user to see the moving progress bar...if you want so reply me i will give you the coding of how to use the progress bar...

And i start service in my MainActivity just to try:
Intent i = new Intent(context, SpeechActivationService.class);
startService(i);
It detect the voice input...and TOO MUCH!!! Every time it detects something it's a "bipbip". Too many bips!! It's frustrating.. I only want that it starts when i say "hello phone" or "start" or a specific word!! I try to look at this https://github.com/gast-lib/gast-lib/blob/master/library/src/root/gast/speech/activation/WordActivator.java but really i don't know how use this library. I try see this question onCreate of android service not called but i not understand exactly what i have to do.. Anyway, i already import the gast library.. I only need to know how use it. Anyone can help me step by step? Thanks

Use setStreamSolo(AudioManager.STREAM_VOICE_CALL, true) instead of setStreamMute. Remember to add setStreamSolo(AudioManager.STREAM_VOICE_CALL, false) in case MSG_RECOGNIZER_CANCEL
