I want to scan barcode that contains REST API, result.getContents will receive url . I have try to fill barcode with json format without using uriparse below and it's work. My problem is how to convert rest api to json.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result != null){
if (result.getContents() == null){
Toast.makeText(this, "Result not found", Toast.LENGTH_SHORT).show();
}else{
// if qrcode are fil
try{
String url = Uri.parse(result.getContents())
.buildUpon()
.build()
.toString();
// converting the data json
JSONObject object = new JSONObject(url);
// setting value to textview
textViewName.setText(object.getString("ceramics_name"));
textViewDisplay.setText(object.getString("ceramics_category"));
textViewStorage.setText(object.getString("storage_stock"));
Toast.makeText(this, result.getContents(), Toast.LENGTH_SHORT).show();
}catch (JSONException e){
e.printStackTrace();
Toast.makeText(this, result.getContents(), Toast.LENGTH_SHORT).show();
}

I want to send multiple images using multipart volley in this format. the format that i have written below is in swift language:
multipartFormData.append(imageData, withName: "nverness\(i).jpg", fileName: "Inverness\(i).jpg" , mimeType: "image/jpeg")
I'm getting multiple images from gallery and save in list. This is done from my side and working perfectly. I want to send this list of images on server using the format that i have written above.
My code is here:
pickImages.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (ActivityCompat.checkSelfPermission(getContext(),
Manifest.permission.READ_EXTERNAL_STORAGE)!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(getActivity(),new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},100);
return;
}
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE,true);
intent.setType("image/*");
startActivityForResult(intent,1);
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1){
bitmaps = new ArrayList<>();
ClipData clipData = data.getClipData();
if (clipData != null){
for (int i =0 ; i < clipData.getItemCount() ; i++){
Uri imageUri = clipData.getItemAt(i).getUri();
try {
InputStream is = getContext().getContentResolver().openInputStream(imageUri);
Bitmap bitmap = BitmapFactory.decodeStream(is);
bitmaps.add(bitmap);
Toast.makeText(getContext(), "Images successfully added", Toast.LENGTH_SHORT).show();
}
catch (FileNotFoundException e){
Toast.makeText(getContext(), e.toString(), Toast.LENGTH_SHORT).show();
}
}
}else {
Uri imageUri = data.getData();
try {
InputStream is = getContext().getContentResolver().openInputStream(imageUri);
Bitmap bitmap = BitmapFactory.decodeStream(is);
bitmaps.add(bitmap);
Toast.makeText(getContext(), "Images successfully added here", Toast.LENGTH_SHORT).show();
}
catch (FileNotFoundException e){
Toast.makeText(getContext(), e.toString(), Toast.LENGTH_SHORT).show();
}
}
}
}
how can i send this list to the server using volley android?
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?
After zxing scans a barcode how do I get it to search for a barcode saved in a text file saved in the raw resources folder? Do these need to be separate activities? I feel like this is a simple task. I have the scanner working perfect I am hung up on how to compare scan result with txt file.

Toast.makeText(this, "scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
}
} else {

if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Cursor c = db.getWordMatches(query, null);

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 am trying to add in my App a function to use the camera to store photos in my device.
At the beginning i use the camera like this:
mButtonCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
count++;
String file = dir+prova+".jpg";
File newFile = new File(file);
try {
newFile.createNewFile();
}catch (IOException e){}
Uri outputFileUri = Uri.fromFile(newFile);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,outputFileUri);
Log.v("CameraDemo", "Pic savedNO");
startActivityForResult(cameraIntent, TAKE_PHOTO_CODE);
}
});
And then for the OnActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
Log.v("CameraDemo", "Pic saved");
Log.v("Salva Foto", dir+prova+".jpg");
myDBHandler.addPhoto(prova,dir+prova+".jpg");
}
}
Until here evrything is ok but when I try to retrieve the photo using this:
InputStream URLcontent = null;
try {
URLcontent = (InputStream) new URL(fotoSI).getContent();
} catch (IOException e) {
e.printStackTrace();
}
Drawable image = Drawable.createFromStream(URLcontent, fotoSI);
mImageCamera.setImageDrawable(image);
It doesn´t return any photo that is what the Log says me:
java.net.MalformedURLException: Protocol not found: /storage/emulated/0/Pictures/
I am trying everything but without results.
