Image size and dimensions reduce when I capture from camera

Using this to open camera:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
and in OnActivityResult:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null) {
if (requestCode == REQUEST_CAMERA && resultCode == RESULT_OK)
{
onCaptureImageResult(data);
}
}
private void onCaptureImageResult(Intent data) {
if (data != null) {
cameraBitMap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
cameraBitMap.compress(Bitmap.CompressFormat.JPEG,100, bytes);
cameraFilePath = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
FileOutputStream fo;
try {
cameraFilePath.createNewFile();
fo = new FileOutputStream(cameraFilePath);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(cameraFilePath.getAbsolutePath(), options);
imageHeight = options.outHeight;
imageWidth = options.outWidth;
camImagePath = String.valueOf(cameraFilePath);
String fileName = camImagePath.substring(camImagePath.lastIndexOf("/") + 1);
txt_FileName.setText(fileName);
txt_FileName.setVisibility(View.VISIBLE);
btn_ImageTest.setImageBitmap(cameraBitMap);
}
}
I want the original size image to display when I capture it from the camera.

Use Intent like this. Here first give image name .
//declare globally
private static final int CAMERA_CODE = 101 ;
private Uri mImageCaptureUri;
Start Intent as below.
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp1.jpg");
if (f.exists()) {
f.delete();
}
mImageCaptureUri = Uri.fromFile(f);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
startActivityForResult(intent, CAMERA_CODE);
And in onActivityResult :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CODE && resultCode == RESULT_OK) {
System.out.println("Camera Image URI : " + mImageCaptureUri);
String path = mImageCaptureUri.getPath();
if (new File(path).exists()) {
Toast.makeText(MainActivity.this, "Path is Exists..", Toast.LENGTH_LONG).show();
}
btn_ImageTest.setImageURI(mImageCaptureUri);
}
}

You need to create temporary file before you start Camera Activity Intent.
Anything that using below code or similar like that after you take image using camera actually is a thumbnail image which is reduced the original quality.
This is the code that I meant:
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
Refer Here for more info
This are the solution that you want
First You need to create temporary file.
Convert the temporary file into URI
Pass URI data to Camera intent by using putExtra method.
Open Camera Activity intent.
Handle onActivityResult if user cancel or accept the image from Camera Activity intent.
Below are the method you can use for step by step mentioned above.
Create Temporary 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
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
Convert Temporary file to URI and invoke camera activity intent.
static final int REQUEST_TAKE_PHOTO = 1;
Uri photoURI;
File photoFile;
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
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) {
photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
Now you already have File location path created before Camera Activity intent called. You can handle RESULT_OK(Show image) or RESULT_CANCELED(Delete temporary image).
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
mImageView.setImageURI(photoURI );
}else{
photoFile.delete();
}
}
*Take note on getUriForFile which returns a content:// URI. For more recent apps targeting Android 7.0 (API level 24) and higher, passing a file:// URI across a package boundary causes a FileUriExposedException. Therefore, we now present a more generic way of storing images using a FileProvider.
Full documentation is here for reference.
Taking Photo Simply

Get Image From Camera result null in data onActivityResult

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

Trying to take a picture and then store it + have access to it

So, I have an app where I want to take a picture, store it to internal storage, and then be able to retrieve it later (presumably via its Uri). Here is what I have thus far:
This code is triggered when my custom camera button is pressed.
cameraButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Intent takePic = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = herp(MEDIA_TYPE_IMAGE);
if (file != null) {
fileUri = getOutputMediaFileUri(file);
Log.d("AddRecipeActivity", fileUri.toString());
takePic.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePic, CAMERA_REQUEST);
}
}
});
Next, I've defined two methods later on in the code(mostly taken from the android developer site):
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(File file){
return Uri.fromFile(file);
}
/** Create a File for saving an image or video */
public File herp(int type){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
Boolean a = false;
String externalDirectory= getFilesDir().getAbsolutePath();
File folder= new File(externalDirectory + "/NewFolder");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (!folder.exists()){
a = folder.mkdirs();
Log.d("AddRecipeActivity", String.valueOf(a));
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(folder.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else {
return null;
}
if(mediaFile == null){
Log.d("AddRecipeActivity", "Media file is null");
}
return mediaFile;
}
When I print my Uri (right before triggering the intent) I get the following output.
04-04 04:22:40.757 22402-22402/scissorkick.com.project2 D/AddRecipeActivity: file:///data/user/0/scissorkick.com.project2/files/NewFolder/IMG_20160404_042240.jpg
Also, when I check if the directory is made, the boolean is true.
When my camera intent's onActivityResult is run, however, the result code is 0.
Why might it fail at this point? I've defined the appropriate permissions in the manifest, and also request external storage write permissions during run time.
Edit: Added the onActivityResult:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == CAMERA_REQUEST){
Log.d("AddRecipe", String.valueOf(resultCode));
if(resultCode == RESULT_OK){
photo = (Bitmap) data.getExtras().get("data");
thumb = ThumbnailUtils.extractThumbnail(photo, 240, 240);
photoView.setImageBitmap(thumb);
//Toast.makeText(getApplicationContext(), "image saved to:\n" + data.getData(), Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_SHORT).show();
}
}
}
There's some nonsense code in the onActivityResult, but the point is that the resultCode = 0 and I don't know why.

In your final activity, put the below code
data.putExtra("uri", uri);//uri = your image uri
getActivity().setResult(""result_code", data);
getActivity().finish();
Then in your onActivityResult code you can get the uri like
Uri uri = data.getExtras().getParcelable("uri");
Then you can use this Uri value to retrieve your image.

There is how i take picture in my app!
When i press my own Image Button
static final int REQUEST_IMAGE_CAPTURE = 1;
static final int REQUEST_TAKE_PHOTO = 1
static final String STATE_PHOTO_PATH = "photoPath";
ImageButton photoButton = (ImageButton) this.findViewById(R.id.take_picture_button);
photoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dispatchTakePictureIntent();
}
});
And here how manage and create/store the file with 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;
}
//Create a new empty file for the photo, and with intent call the camera
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) {
// Error occurred while creating the File
Log.e("Error creating File", String.valueOf(e.getMessage()));
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
//I have the file so now call the Camera
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
private void openImageReader(String imagePath) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri imgUri = Uri.parse(imagePath);
intent.setDataAndType(imgUri, "image/*");
startActivity(intent);
}
In the ActivityResult i only save a record in DB, with the Path of the image so i can retrieve it back and read the photo stored like file.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
//Save the path of image in the DB
db.addCompito(new Compiti(activity_name, null, mCurrentPhotoPath));
refreshListView();
}
}
If you have some screen rotation don't forget to add something like
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Save the user's current game state
savedInstanceState.putString(STATE_PHOTO_PATH, mCurrentPhotoPath);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}
public void onRestoreInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can restore the view hierarchy
super.onRestoreInstanceState(savedInstanceState);
// Restore state members from saved instance
mCurrentPhotoPath = savedInstanceState.getString(STATE_PHOTO_PATH);
}
WHY?
Because when the rotation change you can lose the file that you have created for the "new photo" and when you accept it and save it, your photopath is null and no image is created.

Image captured from camera not displaying in imageview android

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.

How to display image taken with camera in Android

I'm trying to write an app that will take a picture with the native Android Camera app and then display the picture I just took in a new activity. This is my take picture method.
private static 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;
}
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) {
}
int t =5;
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
This works; the camera app opens up and the image is saved. However, this is my display image method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String j = MainActivity.mCurrentPhotoPath;
Bitmap myBitmap = BitmapFactory.decodeFile(j);
ImageView myImage = new ImageView(this);
myImage.setImageBitmap(myBitmap);
setContentView(myImage);
}
Now I tested to see if the filename path was being recorded, and it was. String j does indeed have the path. But, the system cannot run the .decodeFile(String j) method; it says that no such file exists. What do I do to display the image?

If you are using the native camera, you will get the resulting picture in onActivityResult() given that you start the camera app using startActivityForResult(). You can then get a reference to the picture's path as follows (from the docs):
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
}
You can then pass this path to the new Activity via an Intent and decode the Bitmap accordingly.
