Camera Intent returns no file path - android

I have a problem with my camera Intent. It saves the pictures to the storage, but it doesn't return the file path to my activity. When i remove the EXTRA_OUTPUT it returns the file path, but then the images have just a very small size. Is there any solution to get the pictures with original size without using EXTRA_OUTPUT?
Here is my code:
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.btnImageCapture:
preinsertedUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, new ContentValues());
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, preinsertedUri);
startActivityForResult(intent, OPEN_CAMERA);
break;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode){
case OPEN_CAMERA:
if (resultCode == RESULT_OK && data != null) {
Uri imageUri = null;
imageUri = data.getData();
if(imageUri == null && preinsertedUri != null){
imageUri = preinsertedUri;
}
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(imageUri, filePathColumn, null, null, null);
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
filePath = cursor.getString(columnIndex);
try {
Bitmap photo = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(filePath);
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
fo.close();
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
}

Try this it might help you.
When I capture the photo from camera so I implement a logic using Cursor and iterate the cursor and get the last photo path which is capture from camera.
It give the path of last capture photo from camera.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
Cursor cursor = getContentResolver().query(Media.EXTERNAL_CONTENT_URI, new String[]{Media.DATA, Media.DATE_ADDED, MediaStore.Images.ImageColumns.ORIENTATION}, Media.DATE_ADDED, null, "date_added ASC");
if(cursor != null && cursor.moveToFirst())
{
do {
uri = Uri.parse(cursor.getString(cursor.getColumnIndex(Media.DATA)));
photoPath = uri.toString();
}while(cursor.moveToNext());
cursor.close();
}

pass value if using front camera with intent method

i want to check if photo is taken with front camera with intent method.
below is code for run the camera
public void runCamera(){
String fileName = "temp.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent takePictureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
startActivityForResult(takePictureIntent, RESULT_CAMERA);
}
then below is activity result to process the taken image.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
...
case RESULT_CAMERA:
if(resultCode == RESULT_OK && mCapturedImageURI!=null){
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(mCapturedImageURI, projection, null, null, null);
String filePath;
if (cursor != null) {
cursor.moveToFirst();
int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
filePath = cursor.getString(column_index_data);
}

filePath = data.getData().getPath();
GeneralizeImage mGI = new GeneralizeImage(this,filePath);
//getOrientationImage();
uploadFileToServer(mGI.Convert());
cursor.close();
}
else{
Toast.makeText(this, "Try Again", Toast.LENGTH_LONG).show();

break;
i appreciate any help from you guys, thanks.
You can pass parameter in your intent to open front camera.
Try this
takePictureIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);

Select bitmap image from gallary and on button click save to Sdcard

hello very good noon to all.Actually i want to select an image from gallery and then i want to save the selected image in Sdcard which is available in android device.
pick image from Sd card:
Intent mediaChooser = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);
// comma-separated MIME types
mediaChooser.setType("image/*");
startActivityForResult(mediaChooser, RESULT_LOAD_WATER_IMAGE);
And On Activity Result :
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 0:
if (resultCode == RESULT_OK) {
String path;
path = getRealPathFromURI(data.getData());
}
break;
}
Implementation Of getRealPathFromURI:
public String getRealPathFromURI(Uri contentUri) {
try {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
} catch (Exception e) {
return contentUri.getPath();
}
}
Save Image To Sd Card On Click:
// TODO Auto-generated method stub
String root = Environment.getExternalStorageDirectory()
.toString();
File myDir = new File(root + "/Your Folder Name");
myDir.mkdirs();
String fname = "Your File Name";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try
{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
System.out.println("error" + e);
}
Using the code below, you can pick up an image from gallery
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
After that, the picked up image will be return by the onActivityResult() method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == Activity.RESULT_OK && requestCode == PICK_IMAGE && data != null && data.getData() != null) {
Uri _uri = data.getData();
Cursor cursor = getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);
cursor.moveToFirst();
//Get the image file path
final String imageFilePath = cursor.getString(0);
cursor.close();
//save it the sdcard
saveToSDCard(imageFilePath);
}
super.onActivityResult(requestCode, resultCode, data);
}

Getting path of captured image in Android using camera intent

I have been trying to get path of captured image in order to delete image. Found many answers on StackOverflow but none of them are working for me. I got the following answer:
private String getLastImagePath() {
final String[] imageColumns = { MediaStore.Images.Media._ID,
MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID + " DESC";
Cursor imageCursor = POS.this.getContentResolver().query(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns,
null, null, imageOrderBy);
if (imageCursor.moveToFirst()) {
// int id = imageCursor.getInt(imageCursor
// .getColumnIndex(MediaStore.Images.Media._ID));
String fullPath = imageCursor.getString(imageCursor
.getColumnIndex(MediaStore.Images.Media.DATA));
return fullPath;
} else {
return "";
}
}
This code works in Samsung tab but doesn't work in Lenovo tab and i-ball tab.
So, can anyone help me find another solution to do the same?
Any help will be appreciated. Thank you.
This is my onActivityResult:
if (requestCode == CmsInter.CAMERA_REQUEST && resultCode == RESULT_OK) {
//Bitmap photo = null;
//photo = (Bitmap) data.getExtras().get("data");
String txt = "";
if (im != null) {
String result = "";
//im.setImageBitmap(photo);
im.setTag("2");
int index = im.getId();
String path = getLastImagePath();
try {
bitmap1 = BitmapFactory.decodeFile(path, options);
bitmap = Bitmap.createScaledBitmap(bitmap1, 512, 400, false);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] bytData = baos.toByteArray();
try {
baos.close();
} catch (IOException e) {
e.printStackTrace();
}
result = Base64.encode(bytData);
bytData = null;
} catch (OutOfMemoryError ooM) {
System.out.println("OutOfMemory Exception----->" + ooM);
bitmap1.recycle();
bitmap.recycle();
} finally {
bitmap1.recycle();
bitmap.recycle();
}
}
}
Try like this
Pass Camera Intent like below
Intent intent = new Intent(this);
startActivityForResult(intent, REQ_CAMERA_IMAGE);
And after capturing image Write an OnActivityResult as below
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
System.out.println(mImageCaptureUri);
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
String path = "";
if (getContentResolver() != null) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
path = cursor.getString(idx);
cursor.close();
}
}
return path;
}
And check log.
Edit:
Lots of people are asking how to not get a thumbnail. You need to add this code instead for the getImageUri method:
public Uri getImageUri(Context inContext, Bitmap inImage) {
Bitmap OutImage = Bitmap.createScaledBitmap(inImage, 1000, 1000,true);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), OutImage, "Title", null);
return Uri.parse(path);
}
The other method Compresses the file. You can adjust the size by changing the number 1000,1000
There is a solution to create file (on external cache dir or anywhere else) and put this file's uri as output extra to camera intent - this will define path where taken picture will be stored.
Here is an example:
File file;
Uri fileUri;
final int RC_TAKE_PHOTO = 1;
private void takePhoto() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
file = new File(getActivity().getExternalCacheDir(),
String.valueOf(System.currentTimeMillis()) + ".jpg");
fileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
getActivity().startActivityForResult(intent, RC_TAKE_PHOTO);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_TAKE_PHOTO && resultCode == RESULT_OK) {
//do whatever you need with taken photo using file or fileUri
}
}
}
Then if you don't need the file anymore, you can delete it using file.delete();
By the way, files from cache dir will be removed when user clears app's cache from apps settings.
Try this method to get path of original image captured by camera.
public String getOriginalImagePath() {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToLast();
return cursor.getString(column_index_data);
}
This method will return path of the last image captured by camera. So this path would be of original image not of thumbnail bitmap.
Here I updated the sample code in Kotlin. Please note on Nougat and above version Uri.fromFile(file) is not working and it crashes the app for that need to implement FileProvider which is safest way to send files from intent. For implementing this refer this answer or this article
private fun takePhotoFromCamera() {
val isDeviceSupportCamera: Boolean = this.packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)
if (isDeviceSupportCamera) {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
file = File(getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS + "/attachments")!!.path,
System.currentTimeMillis().toString() + ".jpg")
// fileUri = Uri.fromFile(file)
fileUri = FileProvider.getUriForFile(this, this.applicationContext.packageName + ".provider", file!!)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri)
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
takePictureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
}
startActivityForResult(takePictureIntent, Constants.REQUEST_CODE_IMAGE_CAPTURE)
}
} else {
Toast.makeText(this, this.getString(R.string.camera_not_supported), Toast.LENGTH_SHORT).show()
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK) {
if(requestCode == Constants.REQUEST_CODE_IMAGE_CAPTURE) {
realPath = file?.path
//do what ever you want to do
}
}
}
Please refer to Google Documentation:
Camera - Photo Basics
try this
String[] projection = { MediaStore.Images.Media.DATA };
#SuppressWarnings("deprecation")
Cursor cursor = managedQuery(mCapturedImageURI, projection,
null, null, null);
int column_index_data = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
image_path = cursor.getString(column_index_data);
Log.e("path of image from CAMERA......******************.........",
image_path + "");
for capturing image:
String fileName = "temp.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
mCapturedImageURI = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
values.clear();

Get file path of image on Android

I have an app that can make pictures and upload them. The upload requires the file path of the photo but I can't get it.
This is my code:
public void maakfoto (View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
}
}
Please help me to get the file path.
Posting to Twitter needs the image's actual path on the device to be sent in the request to post. I was finding it mighty difficult to get the actual path and more often than not I would get the wrong path.
To counter that, once you have a Bitmap, I use that to get the URI from using the getImageUri(). Subsequently, I use the tempUri Uri instance to get the actual path as it is on the device.
This is production code and naturally tested. ;-)
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
// CALL THIS METHOD TO GET THE URI FROM THE BITMAP
Uri tempUri = getImageUri(getApplicationContext(), photo);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(tempUri));
System.out.println(mImageCaptureUri);
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
Try out with mImageCaptureUri.getPath(); By Below Way :
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Get your Image Path
String Path=mImageCaptureUri.getPath();
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
}
In order to take a picture you have to determine a path where you would like the image saved and pass that as an extra in the intent, for example:
private void capture(){
String directoryPath = Environment.getExternalStorageDirectory() + "/" + IMAGE_DIRECTORY + "/";
String filePath = directoryPath+Long.toHexString(System.currentTimeMillis())+".jpg";
File directory = new File(directoryPath);
if (!directory.exists()) {
directory.mkdirs();
}
this.capturePath = filePath; // you will process the image from this path if the capture goes well
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra( MediaStore.EXTRA_OUTPUT, Uri.fromFile( new File(filePath) ) );
startActivityForResult(intent, REQUEST_CAPTURE);
}
I just copied the above portion from another answer I gave.
However to warn you there are a lot of inconsitencies with image capture behavior between devices that you should look out for.
Here is an issue I ran into on some HTC devices, where it would save in the location I passed and in it's default location resulting in duplicate images on the device:
Deleting a gallery image after camera intent photo taken
I am doing this on click of Button.
private static final int CAMERA_PIC_REQUEST = 1;
private View.OnClickListener OpenCamera=new View.OnClickListener() {
#Override
public void onClick(View paramView) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
NewSelectedImageURL=null;
//outfile where we are thinking of saving it
Date date = new Date();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
String newPicFile = RecipeName+ df.format(date) + ".png";
String outPath =Environment.getExternalStorageDirectory() + "/myFolderName/"+ newPicFile ;
File outFile = new File(outPath);
CapturedImageURL=outFile.toString();
Uri outuri = Uri.fromFile(outFile);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, outuri);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
You can get the URL of the recently Captured Image from variable CapturedImageURL
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//////////////////////////////////////
if (requestCode == CAMERA_PIC_REQUEST) {
// do something
if (resultCode == RESULT_OK)
{
Uri uri = null;
if (data != null)
{
uri = data.getData();
}
if (uri == null && CapturedImageURL != null)
{
uri = Uri.fromFile(new File(CapturedImageURL));
}
File file = new File(CapturedImageURL);
if (!file.exists()) {
file.mkdir();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
}
}
}
use this function to get the capture image path
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Uri mImageCaptureUri = intent.getData();
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
knop.setVisibility(Button.VISIBLE);
System.out.println(mImageCaptureUri);
//getImgPath(mImageCaptureUri);// it will return the Capture image path
}
}
public String getImgPath(Uri uri) {
String[] largeFileProjection = { MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA };
String largeFileSort = MediaStore.Images.ImageColumns._ID + " DESC";
Cursor myCursor = this.managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try {
myCursor.moveToFirst();
largeImagePath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
} finally {
myCursor.close();
}
return largeImagePath;
}
You can do like that In Kotlin If you need kotlin code in the future
val myUri = getImageUri(applicationContext, myBitmap!!)
val finalFile = File(getRealPathFromURI(myUri))
fun getImageUri(inContext: Context, inImage: Bitmap): Uri {
val bytes = ByteArrayOutputStream()
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes)
val path = MediaStore.Images.Media.insertImage(inContext.contentResolver, inImage, "Title", null)
return Uri.parse(path)
}
fun getRealPathFromURI(uri: Uri): String {
val cursor = contentResolver.query(uri, null, null, null, null)
cursor!!.moveToFirst()
val idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA)
return cursor.getString(idx)
}
To get the path of all images in android I am using following code
public void allImages()
{
ContentResolver cr = getContentResolver();
Cursor cursor;
Uri allimagessuri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Images.Media._ID + " != 0";
cursor = cr.query(allsongsuri, STAR, selection, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String fullpath = cursor.getString(cursor
.getColumnIndex(MediaStore.Images.Media.DATA));
Log.i("Image path ", fullpath + "");
} while (cursor.moveToNext());
}
cursor.close();
}
}
Simple Pass Intent first
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
And u will get picture path on u onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}

Low picture/image quality when capture from camera

I have one problem. When I try to get picture from camera, the quality is very low.
At first, capture the picture using camera, than save to the directory and at the same time get that picture and show in my app.The picture saved inside directory is a fine quality but when I get it from directory, the quality is low. below is my sample code :
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == CAMERA_PIC_REQUEST) {
Bitmap thumbnail = (Bitmap) intent.getExtras().get("data");
if (g==1)
{
ImageView myImage = (ImageView) findViewById(R.id.img5);
myImage.setImageBitmap(thumbnail);
View a = findViewById(R.id.img5);
a.setVisibility(View.VISIBLE);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byteArray1 = stream.toByteArray();
}
}
any solution/suggestion?
Thanks :)
Solved
The problem solved when I follow the code given by Antrromet below
I have used the following code and this works perfectly fine for me.
values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, PICTURE_RESULT);
and also
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICTURE_RESULT:
if (requestCode == PICTURE_RESULT)
if (resultCode == Activity.RESULT_OK) {
try {
thumbnail = MediaStore.Images.Media.getBitmap(
getContentResolver(), imageUri);
imgView.setImageBitmap(thumbnail);
imageurl = getRealPathFromURI(imageUri);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
and
public String getRealPathFromURI(Uri contentUri) {
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
I will give you something that work for me. I asked the same !
