I am working on speech recognition and need some sample programs.
Can anyone guide me?
Let me cut and paste a bit to show you what code you will need.
EDIT: you can also download a handy abstract class from this project.
You will need this intent (parameterize as you see fit):
public Intent getRecognizeIntent(String promptToUse, int maxResultsToReturn)
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, maxResultsToReturn);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, promptToUse);
return intent;
}
Then you need to send your intent to the speech recognition activity like so,
public void gatherSpeech(String prompt)
{
Intent recognizeIntent = getRecognizeIntent(prompt);
try
{
startActivityForResult(recognizeIntent, SpeechGatherer.VOICE_RECOGNITION_REQUEST_CODE);
}
catch (ActivityNotFoundException actNotFound)
{
Log.w(D_LOG, "did not find the speech activity, not doing it");
}
}
Then you will need to have your activity handle the speech result:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
Log.d("Speech", "GOT SPEECH RESULT " + resultCode + " req: "
+ requestCode);
if (requestCode == SpeechGatherer.VOICE_RECOGNITION_REQUEST_CODE)
{
if (resultCode == RESULT_OK)
{
ArrayList<String> matches = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
Log.d(D_LOG, "matches: ");
for (String match : matches)
{
Log.d(D_LOG, match);
}
}
}
}
For more info see:
http://developer.android.com/resources/articles/speech-input.html
http://developer.android.com/reference/android/speech/RecognizerIntent.html
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html
First need to Showing google speech input dialog like so
/**
* Showing google speech input dialog
* */
private void promptSpeechInput() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
then need to receiving speech input like so.
/**
* Receiving speech input
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput.setText(result.get(0));
}
break;
}
}
}
and need to set REQ_CODE_SPEECH_INPUT
private final int REQ_CODE_SPEECH_INPUT = 100;

I want to put a barcode reader in my android application, I want it to write the barcode it reads to the TextView, but when I read the barcode, it does not print. The code was working before making the Fragment of the page, it was writing automatically, but when I made the Fragment, it did not transfer what it read to the TextView after reading it.
Code :
public class UrunEklemeJavaFragment extends Fragment {
...
scanBtns.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
IntentIntegrator intentIntegrator = new IntentIntegrator(getActivity());
intentIntegrator.setPrompt("Scan");
intentIntegrator.setBeepEnabled(true);
intentIntegrator.setOrientationLocked(true);
intentIntegrator.setCaptureActivity(BarcodeCapture.class);
intentIntegrator.initiateScan();
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
IntentResult intentResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
// if the intentResult is null then
// toast a message as "cancelled"
if (intentResult != null) {
if (intentResult.getContents() == null) {
Toast.makeText(
getActivity(),
"Cancel",
Toast.LENGTH_SHORT
).show();
}
else {
// if the intentResult is not null we'll set
// the content and format of scan message
messageText.setText(intentResult.getContents());
}
}
else {
super.onActivityResult(requestCode, resultCode, data);
}
}
my main purpose is to write the barcode read in the "messageText" section, but I can't, it reads the barcode but does not write the barcode in the section I want.
scanBtns Code SS
onActivityResult Code SS
I am creating a App, which should save reference documents, saved on the device.
I am receiving the content URI for these documents in the following way:
private void selectDocument() {
Intent chooseFile;
chooseFile = new Intent(Intent.ACTION_GET_CONTENT);
chooseFile.addCategory(Intent.CATEGORY_OPENABLE);
chooseFile.setType("*/*");
if (chooseFile.resolveActivity(getPackageManager()) != null)
startActivityForResult(chooseFile, ACTIVITY_CHOOSE_FILE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
if (resultCode != RESULT_OK) return;
if (requestCode == ACTIVITY_CHOOSE_FILE) {
try {
binding.txtLink.setText(URLDecoder.decode(data.getDataString(),"UTF-8"));
binding.btnLink.setTag(false);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
after displaying the url to the user, he should be able to open the document.
And i am not really sure how to do that, since I only get the contentURI.
What i am currently trying is this:
private void openDocument() {
String file = binding.txtLink.getText().toString();
if (file.isEmpty()) {
return;
}
Intent intent;
String extension = file.substring(file.lastIndexOf(".") + 1);
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(file));
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
} else {
Snackbar.make(binding.root, "Keine Anwendung zum öffnen der Datei installiert", Snackbar.LENGTH_LONG).show();
}
}
This already opens the correct App, but they can't find the files.
What would i need to do, to enable this behavior?
Or do i have to copy the files to my app directory and open them from there?
I am using createConfirmDeviceCredentialIntent() for pin authentication in my android application. If I press back button from my pin authentication intent, the createConfirmDeviceCredentialIntent closes and it displays main activity. I want that from that intent if someone presses back button the app should get closed. `KeyguardManager keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Intent i = keyguardManager.createConfirmDeviceCredentialIntent("unlock", "confirm_pattern");
try {
startActivityForResult(i, LOCK_REQUEST_CODE);
} catch (Exception e) {
Log.d("exception occured", e.toString());
}
} #Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case LOCK_REQUEST_CODE:
if (resultCode == RESULT_OK) {
Intent a = new Intent(MainActivity.this, HomeActivity.class);
startActivity(a);
textView.setText("unlock_success");
} else {
textView.setText("unlock_failed");
}
break;
}
}`
I have created two edit texts. And i created two buttons. By clicking on a button, it will ask for user to speak and it will convert the speech to text and it will
be displayed in the edit text.
I have called the voice to text function two times. One for first edit text and other for second edit text. But it displaying the error.
Please help me to solve this problem.
Here is my code:
private void promptSpeechInput1() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput1.setText(result.get(0));
}
break;
}
}
}
//////////////
private void promptSpeechInput2() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput2.setText(result.get(0));
}
break;
}
}
}
And the error shows on the line:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
You are redefining the onActivityResult method. Use only one instance for your purpose
/**
* Receiving speech input and output
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput1.setText(result.get(0));
}
break;
}
case REQ_CODE_SPEECH_OUTPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput2.setText(result.get(0));
}
break;
}
}
}
and modify this in your promptSpeechInput2 method. Use different request code i.e. not REQ_CODE_SPEECH_INPUT else use REQ_CODE_SPEECH_OUTPUT with different value
try {
startActivityForResult(intent, REQ_CODE_SPEECH_OUTPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
I have make payments through PayPal native android mobile sdk. Below is the success response
{"response":{"state":"approved","id":"PAY-someID","create_time":"2017-06-21T18:01:33Z","intent":"sale"},"client":{"platform":"Android","paypal_sdk_version":"2.15.3","product_name":"PayPal-Android-SDK","environment":"sandbox"},"response_type":"payment"}
But when back-end wants to verify with the payment id i.e PAY-someID, it is throwing error json like below every time
[debug] application - verifyPayment mitemreqCppverifpmtrequest(PAY-someID)
[debug] application - verifpmtrequest case mendpointt https://api.sandbox.paypal.com/v1/payments/payment/PAY-someID
[debug] application - tx.get.body{"name":"INVALID_RESOURCE_ID","message":"Requested resource ID was not found.","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#INVALID_RESOURCE_ID","debug_id":"someID"}
Below is the android code
private static final String CONFIG_ENVIRONMENT = PayPalConfiguration.ENVIRONMENT_SANDBOX;
private static PayPalConfiguration config = new PayPalConfiguration()
.environment(CONFIG_ENVIRONMENT)
.clientId(CONFIG_CLIENT_ID)
// The following are only used in PayPalFuturePaymentActivity.
.merchantName("Example Merchant")
.merchantPrivacyPolicyUri(Uri.parse("https://www.example.com/privacy"))
.merchantUserAgreementUri(Uri.parse("https://www.example.com/legal"));
PayPalPayment thingToBuy = getThingToBuy(PayPalPayment.PAYMENT_INTENT_SALE);
Intent intent = new Intent(SampleActivity.this, PaymentActivity.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);
startActivityForResult(intent, REQUEST_CODE_PAYMENT);
return new PayPalPayment(new BigDecimal("0.01"), "USD", "sample item",
paymentIntent);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE_PAYMENT) {
if (resultCode == Activity.RESULT_OK) {
PaymentConfirmation confirm =
data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
if (confirm != null) {
try {
Log.i(TAG, confirm.toJSONObject().toString(4));
}
}
}
The problem is similar to the below
https://github.com/paypal/PayPal-Android-SDK/issues/330
No idea how to solve this.
Try this one this is working code of my Google PlayStore application.
PayPalConfiguration config = new PayPalConfiguration().environment(PayPalConfiguration.ENVIRONMENT_SANDBOX).clientId("Your id");
Intent intent = new Intent(context, PayPalService.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);
startService(intent);
PayPalPayment payment = new PayPalPayment(new BigDecimal(charge), "USD", eventName, PayPalPayment.PAYMENT_INTENT_SALE);
Intent intent = new Intent(activity, PaymentActivity.class);
intent.putExtra(PayPalService.EXTRA_PAYPAL_CONFIGURATION, config);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, payment);
startActivityForResult(intent, 1089);
Don't Forget to stop service in OnDestroy().
#Override
protected void onDestroy() {
stopService(new Intent(this, PayPalService.class));
super.onDestroy();
}
Also stop service inside OnActivityResult When you perform all your task.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == 1089) {
PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
if (confirm != null)
{
try
{
// Your code after successful response.
} catch (JSONException e) {
Log.error(getClass().getName(), e);
}
}
stopService(new Intent(this, PayPalService.class));
} else if (resultCode == Activity.RESULT_CANCELED) {
//
} else if (resultCode == PaymentActivity.RESULT_EXTRAS_INVALID) {
//
}
}
