I have a problem, that when i have taken an image from camera, image not displaying in imageview.
I created the code by referring the following link
http://developer.android.com/training/camera/photobasics.html
I am posting my code, please have a look,
public void takeImage(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "sample_" + 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();
galleryAddPic();
return image;
}
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == REQUEST_IMAGE_CAPTURE) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
}
}catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG).show();
}
}
The image captured is storing in SDcard. But not showing in imageview.
Where i have gone wrong. I have tried a lot. But no result. Is there any way to solve this issue.
this works for me:
Bitmap myBitmap = BitmapFactory.decodeFile(imagePath);
image.setImageBitmap(myBitmap);
You don't need to create the temp file, just put the Uri in the intent. After the capture, check the file existence of that Uri. If it exists, capture has been done successfully.

In my application, the code below enables the user to open the camera and take photo and save to Gallery, the code is working and the photo is saved to the gallery, but the problem is that the photo appears in the gallery rotated and in the end of the gallery with date equal to 1970, please can someone help me to fix these two problems? Thanks in advance. Below is my code:
code of capturing photo:
private void dispatchTakePictureIntent() {
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
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"myapplication.project",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, CAMERA_CAPTURE_TAG);
}
}
}
code of creating image file:
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 = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
currentPhotoPath = image.getAbsolutePath();
return image;
}
method of saving photo to gallery:
public final void notifyMediaStoreScanner(final File file) {
try {
MediaStore.Images.Media.insertImage(getApplicationContext().getContentResolver(),
file.getAbsolutePath(), file.getName(), null);
getApplicationContext().sendBroadcast(new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
OnActivityResult method:
if (requestCode == CAMERA_CAPTURE_TAG && resultCode == Activity.RESULT_OK) {
//Bundle extras = data.getExtras();
//imageBitmap = (Bitmap) extras.get("data");
//imageSelected.setImageBitmap(imageBitmap);
File f =new File(currentPhotoPath);
notifyMediaStoreScanner(f);
}
I'm following android developers guide to capture a high quality image and save it into the storage then display it. The issue is after capturing the image I get redirected to the main activity without displaying the preview though the image was created successfully in the storage
public void take_hq_image(View view) {
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
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider", photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, HIGH_Q_IMAGE_CAPTURE_REQUEST);
}
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == HIGH_Q_IMAGE_CAPTURE_REQUEST && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap bitmap = (Bitmap) extras.get("data");
HQimageView.setImageBitmap(bitmap);
}
}
Saved image path as a string in currentImagePath variable
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 = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
currentImagePath = image.getAbsolutePath();
return image;
}
Then displayed the preview
Bitmap bitmap = BitmapFactory.decodeFile(currentImagePath);
HQimageView.setImageBitmap(bitmap);
I've written some code in a fragment to open the camera app and once a photo is taken, a photo is saved. I cannot get it to save a full size image, its saving a lower res version. Can anyone spot where I've gone wrong?
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
mNewPhotoPath = getContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES) + "/" +
photoFile.getName();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(getContext(),
"com.example.mmackenz.myholidays.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
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 = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
This is what I have in my onActivityResult in case that is relevant:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
File newImage = new File(mNewPhotoPath);
images.add(newImage);
adapter.notifyDataSetChanged();
Photo newPhoto = new Photo(newImage.getAbsolutePath(), newImage.getName(), -1, -1);
DatabaseHandler db = DatabaseHandler.getInstance(getContext());
db.addPhoto(newImage.getAbsolutePath(), newImage.getName(), -1,-1);
}
}
It adds a new file to an array list which is displayed in a recycler view, and also info of the file in a Photos table.
Thanks
I want to get image from camera, using
public void LicenseCameraIntent() {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, PROFILE_REQUEST_CAMERA);
}
Return bitmap, but it works perfectly. Unfortunately image show as a really small size.
So, i have to keep searching until i get
public void licenseCameraIntent() {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
Uri mImageCaptureUri1 = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"tmp_avatar_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri1);
cameraIntent.putExtra("return-data", true);
startActivityForResult(cameraIntent, LICENSE_REQUEST_CAMERA);
}
On OnActivityResult data always show null result. How I can fix this issue. It is possible using first solution but return bigger image?
Thanks
while you are capture image from the camera you have created a file for an image that is your image full path so make it globally.
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);
}
}
and the image file, mCurrentPhotoPath is the full path of image
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;
}
after onActivityResult() you get the image from mCurrentPhotoPath
#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();
}
}
}
For more info, you can check this link Capture Image from Camera and Display in Activity
try this,
public static int REQUEST_CAMERA = 111;
private void cameraIntent() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
code for onStartActivityForResult
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
_FileName = "image file";
capturePic = null;
file_pdf = null;
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
//mImageView.setImageBitmap(imageBitmap);
img_ticket_detail.setImageBitmap(imageBitmap);
capturePic = imageBitmap;
}
}
}
also you can use glide library for show image
I'm trying to take a photo with the camera and in the activity result method I want to save it and launch a new activity to display the photo from where I saved it, but the imageView stay empty, I used the code from android developer
and here is my code:
private void dispatchTakePictureIntent() {
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 e) {
e.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
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 = getExternalFilesDir(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;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
//Bundle extras = data.getExtras();
// Bitmap imageBitmap =(Bitmap) extras.get("data");
Intent formIntent= new Intent(MainActivity.this,FormActivity.class);
// formIntent.putExtra("img",imageBitmap);
formIntent.putExtra("path",mCurrentPhotoPath);
startActivity(formIntent);
}
}
the activity that shoud display the photo
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_form);
String path = getIntent().getStringExtra("path");
mImageView = (ImageView) findViewById(R.id.imageView);
File imgFile = new File(path);
Toast.makeText(this, path, Toast.LENGTH_LONG).show();
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
mImageView.setImageBitmap(myBitmap);
}
}
