Android camera/picture orientation issues with Samsung Galaxy S3, S4, S5

Question

I am developing a camera application for Android API 16 to 21 which main and only purpose is to take portrait photo. I am able to take picture with several

Answer 1

I had a similar problem regarding the saved image.

I used something similar to what is described here https://github.com/googlesamples/android-vision/issues/124 by user kinghsumit (the comment from Sep 15, 2016).

I'll copy it here, just in case.

private CameraSource.PictureCallback mPicture = new CameraSource.PictureCallback() {
    @Override
    public void onPictureTaken(byte[] bytes) {
       int orientation = Exif.getOrientation(bytes);
       Bitmap   bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
       switch(orientation) {
           case 90:
               bitmapPicture= rotateImage(bitmap, 90);
               break;
           case 180:
               bitmapPicture= rotateImage(bitmap, 180);
               break;
           case 270:
               bitmapPicture= rotateImage(bitmap, 270);
               break;
           case 0:
               // if orientation is zero we don't need to rotate this
           default:
               break;
       }
       //write your code here to save bitmap 
   }
}

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);
}

Below class is used to get orientation from byte[] data.

public class Exif {
    private static final String TAG = "CameraExif";

    // Returns the degrees in clockwise. Values are 0, 90, 180, or 270.
    public static int getOrientation(byte[] jpeg) {
        if (jpeg == null) {
            return 0;
        }

        int offset = 0;
        int length = 0;

        // ISO/IEC 10918-1:1993(E)
        while (offset + 3 < jpeg.length && (jpeg[offset++] & 0xFF) == 0xFF) {
            int marker = jpeg[offset] & 0xFF;

            // Check if the marker is a padding.
            if (marker == 0xFF) {
                continue;
            }
            offset++;

            // Check if the marker is SOI or TEM.
            if (marker == 0xD8 || marker == 0x01) {
                continue;
            }
            // Check if the marker is EOI or SOS.
            if (marker == 0xD9 || marker == 0xDA) {
                break;
            }

            // Get the length and check if it is reasonable.
            length = pack(jpeg, offset, 2, false);
            if (length < 2 || offset + length > jpeg.length) {
                Log.e(TAG, "Invalid length");
                return 0;
            }

            // Break if the marker is EXIF in APP1.
            if (marker == 0xE1 && length >= 8 &&
                    pack(jpeg, offset + 2, 4, false) == 0x45786966 &&
                    pack(jpeg, offset + 6, 2, false) == 0) {
                offset += 8;
                length -= 8;
                break;
            }

            // Skip other markers.
            offset += length;
            length = 0;
        }

        // JEITA CP-3451 Exif Version 2.2
        if (length > 8) {
            // Identify the byte order.
            int tag = pack(jpeg, offset, 4, false);
            if (tag != 0x49492A00 && tag != 0x4D4D002A) {
                Log.e(TAG, "Invalid byte order");
                return 0;
            }
            boolean littleEndian = (tag == 0x49492A00);

            // Get the offset and check if it is reasonable.
            int count = pack(jpeg, offset + 4, 4, littleEndian) + 2;
            if (count < 10 || count > length) {
                Log.e(TAG, "Invalid offset");
                return 0;
            }
            offset += count;
            length -= count;

            // Get the count and go through all the elements.
            count = pack(jpeg, offset - 2, 2, littleEndian);
            while (count-- > 0 && length >= 12) {
                // Get the tag and check if it is orientation.
                tag = pack(jpeg, offset, 2, littleEndian);
                if (tag == 0x0112) {
                    // We do not really care about type and count, do we?
                    int orientation = pack(jpeg, offset + 8, 2, littleEndian);
                    switch (orientation) {
                        case 1:
                            return 0;
                        case 3:
                            return 180;
                        case 6:
                            return 90;
                        case 8:
                            return 270;
                    }
                    Log.i(TAG, "Unsupported orientation");
                    return 0;
                }
                offset += 12;
                length -= 12;
            }
        }

        Log.i(TAG, "Orientation not found");
        return 0;
    }

    private static int pack(byte[] bytes, int offset, int length, boolean littleEndian) {
        int step = 1;
        if (littleEndian) {
            offset += length - 1;
            step = -1;
        }

        int value = 0;
        while (length-- > 0) {
            value = (value << 8) | (bytes[offset] & 0xFF);
            offset += step;
        }
        return value;
    }
}

It worked for me, except for the Nexus 5x, but that's because that device has a peculiar issue due to its construction.

I hope this helps you!

Answer 2

I used this AndroidCameraUtil. It helped me a lot on this issue.

Answer 3

You can try to use Camera parameters to fix rotation issue.

Camera.Parameters parameters = camera.getParameters();
parameters.set("orientation", "portrait");
parameters.setRotation(90);
camera.setParameters(parameters);

Answer 4

It is because the phone still save in landscape and put the meta data as 90 degree. You can try check the exif, rotate the bitmap before put in image view. To check exif, use something like below:

    int orientation = -1;

    ExifInterface exif = new ExifInterface(imagePath);

    int exifOrientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 
            ExifInterface.ORIENTATION_NORMAL);

    switch (exifOrientation) {
        case ExifInterface.ORIENTATION_ROTATE_270:
            orientation = 270;

            break;
        case ExifInterface.ORIENTATION_ROTATE_180:
            orientation = 180;

            break;
        case ExifInterface.ORIENTATION_ROTATE_90:
            orientation = 90;

            break;

        case ExifInterface.ORIENTATION_NORMAL:
            orientation = 0;

            break;
        default:
            break;
    }
