Auto image moved from portrait to album

I take a photo and save it to an SD Card , and then view it from the SD Card to ImageView , but I get it rotated ...

I take it in Portrait mode , but I get the resulting image in Landscape mode ...

Is there something I am missing?

ExifUtil.java class found here

 /** * Displaying captured image/video on the screen * */ private void previewMedia(boolean isImage) { // Checking whether captured media is image or video if (isImage) { imgPreview.setVisibility(View.VISIBLE); final Bitmap bitmap = BitmapFactory.decodeFile(filePath); Bitmap orientedBitmap = ExifUtil.rotateBitmap(filePath, bitmap); imgPreview.setImageBitmap(orientedBitmap); } else { imgPreview.setVisibility(View.GONE); } }

but still showing rotated image in ImageView ...

For proper orientation you need to use EXIF with ORIENTATION_UNDEFINED .

 ExifInterface exif = null; try { exif = new ExifInterface(path); } catch (IOException e) { e.printStackTrace(); } int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);

And rotate the bitmap:

 Bitmap bmRotated = rotateBitmap(bitmap, orientation);

If the image (photograph) was taken by a program made by you, you must set Parameters.setRotation with the correct rotation value.

This, depending on the camera drive, rotates the image before saving or saves the rotation value in exif TAG_ORIENTATION.

Therefore, if TAG_ORIENTATION is null or zero, the image is in the correct orientation, otherwise you must rotate the image according to the value in TAG_ORIENTATION.

THE CODE

Get orientation from EXIF:

 ExifInterface exif = null; try { exif = new ExifInterface(path); } catch (IOException e) { e.printStackTrace(); } int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);

Rotate the bitmap:

 Bitmap bmRotated = rotateBitmap(bitmap, orientation);

Bitmap rotation method:

 public static Bitmap rotateBitmap(Bitmap bitmap, int orientation) { Matrix matrix = new Matrix(); switch (orientation) { case ExifInterface.ORIENTATION_NORMAL: return bitmap; case ExifInterface.ORIENTATION_FLIP_HORIZONTAL: matrix.setScale(-1, 1); break; case ExifInterface.ORIENTATION_ROTATE_180: matrix.setRotate(180); break; case ExifInterface.ORIENTATION_FLIP_VERTICAL: matrix.setRotate(180); matrix.postScale(-1, 1); break; case ExifInterface.ORIENTATION_TRANSPOSE: matrix.setRotate(90); matrix.postScale(-1, 1); break; case ExifInterface.ORIENTATION_ROTATE_90: matrix.setRotate(90); break; case ExifInterface.ORIENTATION_TRANSVERSE: matrix.setRotate(-90); matrix.postScale(-1, 1); break; case ExifInterface.ORIENTATION_ROTATE_270: matrix.setRotate(-90); break; default: return bitmap; } try { Bitmap bmRotated = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true); bitmap.recycle(); return bmRotated; } catch (OutOfMemoryError e) { e.printStackTrace(); return null; } }
