Is it possible to extend the Voice Search app? I know I can add a button in my own app to launch the voice recognition dialog, but I was wondering if I could extend the voice search app that launches automatically when you long press the physical "search" key.
send text to [contact] [message]
listen to [artist/song/album]
call [business]
call [contact]
send email to [contact] [message]
go to [website]
note to self [note]
navigate to [location/business name]
directions to [location/business name]
map of [location]
I'd basically like to add my own action to the above list.
Is this possible or will I have to create my own?
In a word, no. The app doesn't have the extension points you are looking for. You would have to write your own app entirely, which is something that others have done.
A simple method to Handle Voice Search
Step 1 Call this method on button click
public void startVoiceRecognition() {
Intent intent = new Intent("android.speech.action.RECOGNIZE_SPEECH");
intent.putExtra("android.speech.extra.LANGUAGE_MODEL", "free_form");
intent.putExtra("android.speech.extra.PROMPT", "Speak Now");
this.mContainerActivity.startActivityForResult(intent, 3012);
}
Step 2 Override onActivityResult method
# Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 3012 && resultCode == RESULT_OK) {
ArrayList < String > matches = data.getStringArrayListExtra("android.speech.extra.RESULTS");
String result= matches.get(0);
//Consume result
edittext.setText(result);
}
}
Thats all, DONE

So I am trying to make a simple to do list app where it has only a mic button and the list. I am very new to android app dev, i have managed to figure out a text input into the list and how to get the text to speech up and put the spoken text in a text field. All this was achieved through a mix of tutorials. I can't seem to figure out how to bring the 2 together.
Any tips?
Here I leave you a great tutorial considering that you didnt post any code.
This tutorial, shows you how to make speech recognition with a button and then it makes a list with the possible spoken text. It works perfectly, I tried once.
Try this code to open the mic on button --> OnClickListener.
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
startActivityForResult(intent, nRESULT_SPEECH);
}
nRESULT_SPEECH is your code which you can give anything as 0, 1, 2,etc;
You will get the word spoken in this callback method onActivityResult
#Override public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case nRESULT_SPEECH:
if (null != data) {
ArrayList<String> text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String textCapturedFromVoice=text.get(0);
}
break;
}
}
Once u will get the text in textCapturedFromVoice, you can add this to ur list.
I've implementing voice-search on my Android-TV app using the following small code
private void displaySpeechRecognizer() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
startActivityForResult(intent, SPEECH_REQUEST_CODE);
}
#Override
public void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == SPEECH_REQUEST_CODE && resultCode == -1) {
List<String> results = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
String spokenText = results.get(0);
Toast.makeText(getActivity(), spokenText, Toast.LENGTH_LONG).show();
}
super.onActivityResult(requestCode, resultCode, data);
}
This is all working well and I get the result back for further processing.
The problem is that I also want to give the user the possibility to enter the search-string manually with the virtual keyboard.
In Googles own apps you do this be simply pressing RIGHT on the remote to give focus to the textbox after pressing the voice-search icon.
In my example above I can see the "built-in-textbox" when I press the search icon but if I try to navigate to it the search is interrupted and closed.
How do I access the search-textbox? This should cancel voice-input and bring up the keyboard instead, just like Play Store app.
Are you using Leanback support library for your Android TV app design?
I guess "Google Play Store app" and "YouTube app" are using BrowseFragment & SearchFragment for search. These Fragments are providing build-in search UI.
For the implementation, see Google's sample source code or SearchFragment – Android TV app Tutorial 12.
I am developing an Android application, I need to embed the Zxing scanner. The application should allow the user to scan a QR Code and then store the QR code ID of the product and parse it from an XML file. As yet, I have used the simple code:
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage(getPackageName());
intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
What this code does is, scans the product and bring me back to the previous screen of my app. I haven't included the entire library from Zxing as I wanted the Barcode scanner to handle it, but it seems I have to do more than I already have done.
You need to make an onActivityResult method that will get the callback once barcode scanner is done. Inside there you will handle the code string and do whatever you like with it.
/*Here is where we come back after the Barcode Scanner is done*/
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
// contents contains whatever the code was
String contents = intent.getStringExtra("SCAN_RESULT");
// Format contains the type of code i.e. UPC, EAN, QRCode etc...
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
Log.i("TAG",format + "\t" + contents);
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel. If the user presses 'back' before a code is scanned.
Log.i("TAG","Canceled");
}
}
}
This example just logs the results, you'll need to expand upon it to do whatever you want with the info you get back from the scanner.
Better still, use the IntentIntegrator class supplied with the project. It wraps up all the details listed here and its documentation already tells you exactly how to integrate it into your app. It deals with things for you like getting the app installed if not already.
I have three buttons that onlongpress bring up my new IntentIntegrator scans via Barcode Scanner. I successfully have/had it scanning and using the code scanned to do something with when it is only one button.
How can I pass a value or something that when "protected void onActivityResult" is called it will know which button it came from so I can do different things with it depending on which button was long pressed.
My current setup is like this:
button1.setOnLongClickListener(this);
button2.setOnLongClickListener(this);
button3.setOnLongClickListener(this);}
}
public boolean onLongClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.initiateScan();
return true;
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
case IntentIntegrator.REQUEST_CODE:
if (resultCode == Activity.RESULT_OK) {
IntentResult intentResult =
IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (intentResult != null) {
String contents = intentResult.getContents();
String format = intentResult.getFormatName();
//do stuff with the scan. But I want to do different stuff depending on which button was pressed.
Two options:
One, you can modify the IntentIntegrator source code so that it takes different REQUEST_CODES as constructor parameters (or just add a setRequestCode parameter). Then in onActivityResult, check for which requestCode was returned (each of your buttons would return a different request code). This would be the recommended approach.
Second option is the hacky one: In your code, create a member variable that tracks which was the last button pressed (check whether the view passed in onLongClick matches button1,button2, or button3), and use that information in onActivityResult to choose what to do with the results passed back from barcode scanner.
The Android platform have a number of "ready easy use" dialog such as
ProgressDialog, DatePickerDialog and TimePickerDialog, these are fire and wait
boxes, that is, they handle UI, right data and return something.
Is there a similar dialogbox for the mediastorage ?
I want something like "AudioFilePickerDialog" which shows a UI to the user
where the user pick a audio file and return the path/uri to the audio file.
Do I need to build this dialog box up myself or does it exists somewhere ?
One of the few examples I have found is
Given an Android music playlist name, how can one find the songs in the playlist?
but this handles playlists.

I found a tutorial for something like a FileChooser here. You should be able to make it only show Music-Files (like .mp3).
Also, to browser the SDcard of your Android Device, you can use the standard Java File-class, like in normal Java.
Try this
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, REQUEST_MEDIA);//REQUEST_MEDIA is some const int to operate with in onActivityResult
here you'll be brought a dialog (activity tbh) to choose an audio from mediastore.
Handle the result in onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_MEDIA && resultCode == RESULT_OK) {
String audioID = data.getDataString();
...
}
}
