Image in gallery is saved with wrong orientation

Question

To take a photo I'm using the camera installed on the device. The photo is saved inside the gallery but is always saved horizontally.
How do I fix it?

This is the intent when click on the button "add 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
                ex.printStackTrace();
            }
            // Continue only if the File was successfully created
            if (photoFile != null) {
                Uri photoURI = null;
                photoURI = galleryAddPic();
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
            }
        }
    }

This is the method createImageFile():

private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        imageFileName = "JPG_" + timeStamp + "_";
        File storageDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(
                imageFileName,  /* prefix */
                ".jpg",         /* suffix */
                storageDir      /* directory */
        );

In the end, this is the method galleryAddPic():

private Uri 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);
        return contentUri;
    }
        // Save a file: path for use with ACTION_VIEW intents
        mCurrentPhotoPath = image.getAbsolutePath();
        return image;
    }

After inserting the photo into the gallery, I can rotate the image as I want it. But in the gallery the image is not rotated well.
So I would like to save the image in the gallery with the right orientation.
Thanks!

You have to Collect information about orientation of picture from (EXIF meta data) because picture orientation depends on the camera built into device . this code reads information from EXIF data and rotate image accordingly

BitmapFactory.Options bounds = new BitmapFactory.Options();
bounds.inJustDecodeBounds = true;
BitmapFactory.decodeFile(file, bounds);

BitmapFactory.Options opts = new BitmapFactory.Options();
Bitmap bm = BitmapFactory.decodeFile(file, opts);
ExifInterface exif = new ExifInterface(file);
String orientString = exif.getAttribute(ExifInterface.TAG_ORIENTATION);
int orientation = orientString != null ? Integer.parseInt(orientString) :  ExifInterface.ORIENTATION_NORMAL;

int rotationAngle = 0;
if (orientation == ExifInterface.ORIENTATION_ROTATE_90) rotationAngle = 90;
if (orientation == ExifInterface.ORIENTATION_ROTATE_180) rotationAngle = 180;
if (orientation == ExifInterface.ORIENTATION_ROTATE_270) rotationAngle = 270;

Matrix matrix = new Matrix();
matrix.setRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bounds.outWidth, bounds.outHeight, matrix, true);

Information from EXIF:

ExifInterface ei = new ExifInterface(photoPath);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
                                     ExifInterface.ORIENTATION_UNDEFINED);

switch(orientation) {

    case ExifInterface.ORIENTATION_ROTATE_90:
        rotateImage(bitmap, 90);
        break;

    case ExifInterface.ORIENTATION_ROTATE_180:
        rotateImage(bitmap, 180);
        break;

    case ExifInterface.ORIENTATION_ROTATE_270:
        rotateImage(bitmap, 270);
        break;

    case ExifInterface.ORIENTATION_NORMAL:

    default:
        break;
}

rotate bitmap method

public static Bitmap rotateImage(Bitmap source, float angle) {
    Matrix matrix = new Matrix();
    matrix.postRotate(angle);
    return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),
                               matrix, true);
}

SAVE Bitmap to Gallery

hope it helps !!

I already do this in a method to show the image in a imageview.and function, but I need to rotate the bitmapt and then store it in the gallery — Ibernato933, Jun 29 '17 at 11:04
Yes, but before the methos addGalleryPic, Bitmap in sull if i call decodeBitmap(path). When take a photo, how do retrive the bitmap? — Ibernato933, Jun 29 '17 at 11:31
Don't you already get Bitmap from here ? 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); } } — Adnan Maqbool, Jun 29 '17 at 11:37
