Why does an image captured using camera intent gets rotated on some devices on Android

Question

I m capturing an image and setting it to image view   public void captureImage          Intent intentCamera   new Intent  android media action IMAGE CAPTURE        File filePhoto   new File Environment getExternalStorageDirectory     Pic jpg        imageUri   Uri fromFile filePhoto       MyApplicationGlobal imageUri   imageUri getPath        intentCamera putExtra MediaStore EXTRA OUTPUT  imageUri       startActivityForResult intentCamera  TAKE PICTURE       Override protected void onActivityResult int requestCode  int resultCode  Intent intentFromCamera        super onActivityResult requestCode  resultCode  intentFromCamera        if  resultCode    RESULT OK  amp  amp  requestCode    TAKE PICTURE             if  intentFromCamera    null                Bundle extras   intentFromCamera getExtras                if  extras containsKey  data                      bitmap    Bitmap  extras get  data                              else                   bitmap   getBitmapFromUri                                    else               bitmap   getBitmapFromUri                         imageView setImageBitmap bitmap           imageView setImageURI imageUri             else            public Bitmap getBitmapFromUri          getContentResolver   notifyChange imageUri  null       ContentResolver cr   getContentResolver        Bitmap bitmap       try           bitmap   android provider MediaStore Images Media getBitmap cr  imageUri           return bitmap            catch  Exception e            e printStackTrace            return null            But the problem is  the image on some devices every time it gets rotated  For example  on a Samsung device it works good  but on a Sony Xperia the image gets rotated by 90 degrees and on Toshiba Thrive  tablet  by 180 degrees

Below code worked with me  it got the bitmap from the fileUri  and do the rotation fixing if required       private fun getCapturedImage selectedPhotoUri  Uri   Bitmap           val bitmap   when               Build VERSION SDK INT  lt  28 - gt  MediaStore Images Media getBitmap                  this contentResolver                  selectedPhotoUri                           else - gt                    val source   ImageDecoder createSource this contentResolver  selectedPhotoUri                  ImageDecoder decodeBitmap source                                      If the image is rotated  fix it         return when  ExifInterface contentResolver run   openInputStream selectedPhotoUri     getAttributeInt              ExifInterface TAG ORIENTATION  ExifInterface ORIENTATION UNDEFINED                 ExifInterface ORIENTATION ROTATE 90 - gt                  Bitmap createBitmap bitmap  0  0  bitmap width  bitmap height  Matrix   apply                       postRotate 90F     true              ExifInterface ORIENTATION ROTATE 180 - gt                  Bitmap createBitmap bitmap  0  0  bitmap width  bitmap height  Matrix   apply                       postRotate 180F     true              ExifInterface ORIENTATION ROTATE 270 - gt                  Bitmap createBitmap bitmap  0  0  bitmap width  bitmap height  Matrix   apply                       postRotate 270F     true              else - gt  bitmap

One line solution   Picasso with context  load  http   i imgur com DvpvklR png   into imageView     Or   Picasso with context  load  file     photoPath  into imageView     This will autodetect rotation and place image in correct orientation  Picasso is a very powerful library for handling images in your app includes  Complex image transformations with minimal memory use

I solved it using a different method  All you have to do is check if the width is greater than height             Matrix rotationMatrix   new Matrix            if finalBitmap getWidth    gt   finalBitmap getHeight                          rotationMatrix setRotate -90                     else                       rotationMatrix setRotate 0                      Bitmap rotatedBitmap   Bitmap createBitmap finalBitmap 0 0 finalBitmap getWidth   finalBitmap getHeight   rotationMatrix true

If you are using Fresco  you can use this -   final ImageRequest imageRequest   ImageRequestBuilder newBuilderWithSource uri   setRotationOptions RotationOptions autoRotate     build     mSimpleDraweeView setController  Fresco newDraweeControllerBuilder        setImageRequest imageRequest       build       This automatically rotates the images based on Exif data   Source  https   frescolib org docs rotation html

Sadly   jason-robinson answer above didn t work for me    Although the rotate function works perfectly   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       I had to do the following to get the orientation as the Exif orientation was always 0  protected void onActivityResult int requestCode  int resultCode  Intent data        super onActivityResult requestCode resultCode data       if  requestCode    RESULT LOAD IMAGE  amp  amp  resultCode    RESULT OK  amp  amp  data    null                Uri selectedImage   data getData                String   orientationColumn    MediaStore Images Media ORIENTATION               Cursor cur   managedQuery imageUri  orientationColumn  null  null  null               int orientation   -1              if  cur    null  amp  amp  cur moveToFirst                          orientation   cur getInt cur getColumnIndex orientationColumn 0                               InputStream imageStream   getContentResolver   openInputStream selectedImage               Bitmap bitmap   BitmapFactory decodeStream imageStream               switch orientation                        case 90                              bitmap   rotateImage chosen image bitmap  90                               break                      case 180                              bitmap   rotateImage chosen image bitmap  180                               break                      case 270                              bitmap   rotateImage chosen image bitmap  270                               break                      default                              break                            imageView setImageBitmap bitmap

Better try to take the picture in a specific orientation   android screenOrientation  landscape  android configChanges  orientation keyboardHidden    For best results give landscape orientation in the cameraview activity

If somebody experiences problems with ExifInterface on Android 4 4  KitKat  for getting the orientation  it might be because of wrong path got from the URI  See a solution for propoer getPath in Stack Overflow question Get real path from URI  Android KitKat new storage access framework

Most phone cameras are landscape  meaning if you take the photo in portrait  the resulting photos will be rotated 90 degrees  In this case  the camera software should populate the Exif data with the orientation that the photo should be viewed in   Note that the below solution depends on the camera software device manufacturer populating the Exif data  so it will work in most cases  but it is not a 100  reliable solution   ExifInterface ei   new ExifInterface photoPath   int orientation   ei getAttributeInt ExifInterface TAG ORIENTATION                                       ExifInterface ORIENTATION UNDEFINED    Bitmap rotatedBitmap   null  switch orientation         case ExifInterface ORIENTATION ROTATE 90          rotatedBitmap   rotateImage bitmap  90           break       case ExifInterface ORIENTATION ROTATE 180          rotatedBitmap   rotateImage bitmap  180           break       case ExifInterface ORIENTATION ROTATE 270          rotatedBitmap   rotateImage bitmap  270           break       case ExifInterface ORIENTATION NORMAL      default          rotatedBitmap   bitmap      Here is the rotateImage 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

Jason Robinson s answer and Sami Eltamawy answer are excelent   Just an improvement to complete the aproach  you should use compat ExifInterface   com android support exifinterface   lastLibVersion   You will be able to instantiate the ExifInterface pior API  lt 24  with InputStream  from ContentResolver  instead of uri paths avoiding  File not found exceptions    https   android-developers googleblog com 2016 12 introducing-the-exifinterface-support-library html

I have spent a lot of time looking for solution for this  And finally managed to do this  Don t forget to upvote  Jason Robinson answer because my is based on his   So first thing  you sholuld know that since Android 7 0 we have to use FileProvider and something called ContentUri  otherwise you will get an annoying error trying to invoke your Intent  This is sample code   Intent intent   new Intent MediaStore ACTION IMAGE CAPTURE   intent putExtra MediaStore EXTRA OUTPUT  getUriFromPath context    Your path to save image      startActivityForResult intent  CAPTURE IMAGE RESULT     Method getUriFromPath Context  String  basis on user version of Android create FileUri  file        or ContentUri  content        and there it is   public Uri getUriFromPath Context context  String destination        File file    new File destination        if  android os Build VERSION SDK INT  gt   android os Build VERSION CODES N            return FileProvider getUriForFile context  context getPackageName       provider   file         else           return Uri fromFile file             After onActivityResult you can catch that uri where image is saved by camera  but now you have to detect camera rotation  here we will use moddified  Jason Robinson answer   First we need to create ExifInterface based on Uri   Nullable public ExifInterface getExifInterface Context context  Uri uri        try           String path   uri toString            if  path startsWith  file                     return new ExifInterface path                     if  android os Build VERSION SDK INT  gt   Build VERSION CODES N                if  path startsWith  content                         InputStream inputStream   context getContentResolver   openInputStream uri                   return new ExifInterface inputStream                                     catch  IOException e            e printStackTrace              return null      Above code can be simplified  but i want to show everything  So from FileUri we can create ExifInterface based on String path  but from ContentUri we can t  Android doesn t support that    In that case we have to use other constructor based on InputStream  Remember this constructor isn t available by default  you have to add additional library   compile  com android support exifinterface XX X X    Now we can use getExifInterface method to get our angle   public float getExifAngle Context context  Uri uri        try           ExifInterface exifInterface   getExifInterface context  uri           if exifInterface    null                return -1f                     int orientation   exifInterface getAttributeInt ExifInterface TAG ORIENTATION                  ExifInterface ORIENTATION UNDEFINED            switch  orientation                case ExifInterface ORIENTATION ROTATE 90                  return 90f              case ExifInterface ORIENTATION ROTATE 180                  return 180f              case ExifInterface ORIENTATION ROTATE 270                  return 270f              case ExifInterface ORIENTATION NORMAL                  return 0f              case ExifInterface ORIENTATION UNDEFINED                  return -1f              default                  return -1f                      catch  Exception e            e printStackTrace            return -1f            Now you have Angle to properly rotate you image

This maybe goes without saying but always remember that you can handle some of these image handling issues on your server  I used responses like the ones contained in this thread to handle the immediate display of the image  However my application requires images to be stored on the server  this is probably a common requirement if you want the image to persist as users switch phones    The solutions contained in many of the threads concerning this topic don t discuss the lack of persistence of the EXIF data which doesn t survive the Bitmap s image compression  meaning you ll need to rotate the image each time your server loads it  Alternatively  you can send the EXIF orientation data to your server  and then rotate the image there if needed   It was easier for me to create a permanent solution on a server because I didn t have to worry about Android s clandestine file paths

Normally it is recommended to solve the problem with the ExifInterface  like  Jason Robinson did suggest  If this approach doesn t work  you could try to look up the Orientation of the latest image taken     private int getImageOrientation        final String   imageColumns     MediaStore Images Media  ID  MediaStore Images ImageColumns ORIENTATION        final String imageOrderBy   MediaStore Images Media  ID   DESC       Cursor cursor   getContentResolver   query MediaStore Images Media EXTERNAL CONTENT URI              imageColumns  null  null  imageOrderBy        if cursor moveToFirst             int orientation   cursor getInt cursor getColumnIndex MediaStore Images ImageColumns ORIENTATION            cursor close            return orientation        else           return 0

Use of Glide library worked for me  Rotation is taken cared of automatically  Bitmap bitmap   Glide with myContext  asBitmap   load imageFilePath  submit SIZE ORIGINAL  SIZE ORIGINAL  get     Then you save that bitmap to a file in JPEG format  for example  If you just want to load into an ImageView instead of saving to a file  Glide with myContext  load imageFilePath  into myImageView

Got an answer for this problem without using ExifInterface  We can get the rotation of the camera either front camera or back camera whichever you are using then while creating the Bitmap we can rotate the bitmap using Matrix postRotate degree   public int getRotationDegree         int degree   0       for  int i   0  i  lt  Camera getNumberOfCameras    i              Camera CameraInfo info   new Camera CameraInfo            Camera getCameraInfo i  info           if  info facing    Camera CameraInfo CAMERA FACING BACK                degree   info orientation               return degree                       return degree      After calculating the rotation you can rotate you bitmap like below    Matrix matrix   new Matrix      matrix postRotate getRotationDegree       Bitmap createBitmap bm  0  0  bm getWidth    bm getHeight    matrix  true     Herare bm should be your bitmap   If you want to know the rotation of your front camera just change Camera CameraInfo CAMERA FACING BACK to Camera CameraInfo CAMERA FACING FRONT above   I hope this helps
