How get Image Uri from Camera? - android

Help pls,
how i can get URI from camera Picture i check some articals and don't understand how dows it works, pls explain me or give some links on this topic here's my code:
private void createDirectory() {
directory = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Meassure Preassure Pic");
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == REQUEST_CODE_PHOTO && resultCode == RESULT_OK) {
if (intent != null && intent.getExtras() != null) {
Bitmap imageBitmap = (Bitmap) intent.getExtras().get("data");
ivPhoto.setImageBitmap(imageBitmap);
}
}
}
public void onClickPhoto(View view) {
Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (pictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(pictureIntent, REQUEST_CODE_PHOTO);
}
}

The onActivityResult method contains the data. Firstly you need to check if the data is null, after that you can use getdata() on returned intent to get URI. You can also get the real path of the captured image if you want to. Below is the code sample :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_GALLERY_CODE && resultCode == Activity.RESULT_OK) {
uri = data.getData();
String filePath = getRealPathFromURIPath(uri, getActivity());
File file = new File(filePath);
Log.d(TAG, "Filename " + file.getName());
}
}

onActivityResult with different intents? [duplicate]

This question already has answers here:
Multiple onActivityResult for 1 Activity
(3 answers)
Closed 5 years ago.
I have an app where I want to use two buttons, one for opening the camera and the other should open the gallery and select a image.
What is the correct way to create the onActivityResult? I started with the camera and it works. I then added the select from gallery button with intent but the first "if"-clause is always triggered becauce REQUEST_TAKE_PHOTO is always true/1. In all the examples I could find they always used final static ints for these kind of tasks.
Should I not use final static ints and set them to the correct state before triggering the onActivityState?
How do people usually solve this?
static final int REQUEST_TAKE_PHOTO = 1;
static final int PICK_IMAGE_REQUEST = 1;
...
cameraButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
}
});
galleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Välj Bild"), PICK_IMAGE_REQUEST);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK && data != null) {
if (requestCode == REQUEST_TAKE_PHOTO) {
try {
setPic();
} catch (IOException e) {
e.printStackTrace();
}
} else if (requestCode == PICK_IMAGE_REQUEST && data.getData() != null) {
Uri uri = data.getData();
mImageView.setImageURI(uri);
}
} else {
Log.d("Error", "Error");
}
}
Why are using same request code fro both request . Change these.
static final int REQUEST_TAKE_PHOTO = 1;
static final int PICK_IMAGE_REQUEST = 1;
request code should be unique to one another so use like .
static final int REQUEST_TAKE_PHOTO = 1;
static final int PICK_IMAGE_REQUEST = 2;
onActivityresult() canbe like below .
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_TAKE_PHOTO) {
if (resultCode == RESULT_OK) {
// camera picture
} else {
// request canceled
}
} else if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK) {
if (data != null) {
Uri uri = data.getData();
mImageView.setImageURI(uri);
}
}
}
you can use switch statement in your OnActivityResult like this:
And you need to change your int values too Like this:
static final int REQUEST_TAKE_PHOTO = 1;
static final int PICK_IMAGE_REQUEST = 2;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
switch (requestCode) {
case REQUEST_TAKE_PHOTO :
/// your code for this
break;
case PICK_IMAGE_REQUEST :
// your code here for image request.
break;
}
}catch (Exception e) {
}

Uri Returns null in onActivityResult

I am doing a module which needs to convert image into pdf. i have successfully implemented the camera and can display its image. but my problem is getting the uri of that image. i saw a code snippet here in StackOverflow and followed it but it returns null.
here is my sample code:
#Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
uri = data.getData();
if(uri == null)
{
tvUri.setText("null");
}else{
tvUri.setText(uri.toString());
}
}
}
to test if it is null, i proceeded to set the textview into its value if it has one, but if not, then i set it to null.
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
Uri u = intent.getData();
}
try this
uri = data.getExtras().get("data");
instead of
uri = data.getData();

Images are not show in ListView Item on Camera click in Android [duplicate]

I need to push an intent to default camera application to make it take a photo, save it and return an URI. Is there any way to do this?
private static final int TAKE_PICTURE = 1;
private Uri imageUri;
public void takePhoto(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
}
Try the following I found here
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == 0) {
String result = data.toURI();
// ...
}
}
It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.
Request this permission on the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
On your Activity, start by defining this:
static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;
Then fire this Intent in an onClick:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
Log.i(TAG, "IOException");
}
// Continue only if the File was successfully created
if (photoFile != null) {
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
}
}
Add the following support method:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, // prefix
".jpg", // suffix
storageDir // directory
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
Then receive the result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
mImageView.setImageBitmap(mImageBitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.
I found a pretty simple way to do this. Use a button to open it using an on click listener to start the function openc(), like this:
String fileloc;
private void openc()
{
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = null;
try
{
f = File.createTempFile("temppic",".jpg",getApplicationContext().getCacheDir());
if (takePictureIntent.resolveActivity(getPackageManager()) != null)
{
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,FileProvider.getUriForFile(profile.this, BuildConfig.APPLICATION_ID+".provider",f));
fileloc = Uri.fromFile(f)+"";
Log.d("texts", "openc: "+fileloc);
startActivityForResult(takePictureIntent, 3);
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 3 && resultCode == RESULT_OK) {
Log.d("texts", "onActivityResult: "+fileloc);
// fileloc is the uri of the file so do whatever with it
}
}
You can do whatever you want with the uri location string. For instance, I send it to an image cropper to crop the image.
Try the following I found Here's a link
If your app targets M and above and declares as using the CAMERA permission which is not granted, then attempting to use this action will result in a SecurityException.
EasyImage.openCamera(Activity activity, int type);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
EasyImage.handleActivityResult(requestCode, resultCode, data, this, new DefaultCallback() {
#Override
public void onImagePickerError(Exception e, EasyImage.ImageSource source, int type) {
//Some error handling
}
#Override
public void onImagesPicked(List<File> imagesFiles, EasyImage.ImageSource source, int type) {
//Handle the images
onPhotosReturned(imagesFiles);
}
});
}
Call the camera through intent, capture images, and save it locally in the gallery.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
someActivityResultLauncher.launch(cameraIntent);}
#Override
public void onActivityResult(ActivityResult result) {
if (result.getResultCode() == RESULT_OK) {
bitmap = (Bitmap) Objects.requireNonNull(result.getData()).getExtras().get("data");
}
imageView.setImageBitmap(bitmap);
saveimage(bitmap);
}
private void saveimage(Bitmap bitmap){
Uri images;
ContentResolver contentResolver = getContentResolver();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q){
images = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);
}else {
images = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
}
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.Images.Media.DISPLAY_NAME, System.currentTimeMillis() +".jpg");
contentValues.put(MediaStore.Images.Media.MIME_TYPE, "images/*");
Uri uri = contentResolver.insert(images, contentValues);
try {
OutputStream outputStream = contentResolver.openOutputStream(Objects.requireNonNull(uri));
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
Objects.requireNonNull(outputStream);
//
}catch (Exception e){
//
e.printStackTrace();
}
}
try this code
Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(photo, CAMERA_PIC_REQUEST);

How can I get the URI with a custom camera in Android?

I'm switching from using the default camera to finally growing a pair and deciding to make a custom camera. It's only showing me how much I don't fully understand.
Here is basically way I have been doing things in the main activity as far as photos go, but it will no longer work:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == PICK_PHOTO_REQUEST) {
if (data == null) {
Toast.makeText(this, "General Error!", Toast.LENGTH_LONG).show();
}
else {
mMediaUri = data.getData();
}
Log.i(TAG, "Media URI: " + mMediaUri);
}
else {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(mMediaUri);
sendBroadcast(mediaScanIntent);
}
(...)
Here is the picture saving function along with a couple others of the new camera:
(...)
#Override
public void onPictureTaken(byte[] data, Camera camera) {
Log.d("Picture taken");
String path = savePictureToFileSystem(data);
setResult(path);
finish();
}
private static String savePictureToFileSystem(byte[] data) {
File file = getOutputMediaFile();
saveToFile(data, file);
return file.getAbsolutePath();
}
private void setResult(String path) {
Intent intent = new Intent();
intent.putExtra(EXTRA_IMAGE_PATH, path);
setResult(RESULT_OK, intent);
}
*Credit to Paul Blundell
(...)
What do I need to do so that the main activity can receive the image's URI in the onactivityresult instead of the path String? Are URIs even applicable when it comes to custom cameras?
Please and thanks.
You use custom camera, but want to do it via Intent? OK, you have the absolute file path in
String abspath = data.getExtras().getString(EXTRA_IMAGE_PATH);
mMediaUri = Uri.fromFile(new File(abspath));
