Android Bitmaps loaded from gallery are rotated in ImageView

Question

When I load an image from the media gallery into a Bitmap  everything is working fine  except that pictures that were shot with the camera while holding the phone vertically  are rotated so that I always get a horizontal picture even though it appears vertical in the gallery  Why is that and how can I load it correctly

Use a Utility to do the Heavy Lifting   9re created a simple utility to handle the heavy lifting of dealing with EXIF data and rotating images to their correct orientation    You can find the utility code here  https   gist github com 9re 1990019  Simply download this  add it to your project s src directory and use ExifUtil rotateBitmap   to get the correct orientation  like so    String imagePath   photoFile getAbsolutePath                   photoFile is a File class  Bitmap myBitmap    BitmapFactory decodeFile imagePath    Bitmap orientedBitmap   ExifUtil rotateBitmap imagePath  myBitmap

Have you looked at the EXIF data of the images  It may know the orientation of the camera when the picture was taken

I solved the problem with the following workaround  Note that I am also scaling the image  which was necessary to avoid OutOfMemoryExceptions   Beware that this solution will not work properly with portrait images or opside-down images  thank you Timmmm for noting   Timmmm s solution above might be the better choice if that is required and it looks more elegant  too  https   stackoverflow com a 8914291 449918  File path          location of your bitmap file int w   512  int h   384     size that does not lead to OutOfMemoryException on Nexus One Bitmap b   BitmapFactory decodeFile path        Hack to determine whether the image is rotated boolean rotated   b getWidth    gt  b getHeight     Bitmap resultBmp   null      If not rotated  just scale it if   rotated        resultBmp   Bitmap createScaledBitmap b  w  h  true       b recycle        b   null      If rotated  scale it by switching width and height and then rotated it   else       Bitmap scaledBmp   Bitmap createScaledBitmap b  h  w  true       b recycle        b   null       Matrix mat   new Matrix        mat postRotate 90       resultBmp   Bitmap createBitmap scaledBmp  0  0  h  w  mat  true           Release image resources     scaledBmp recycle        scaledBmp   null        resultBmp now contains the scaled and rotated image   Cheers

I have melted  Timmmm answer and  Manuel  If you do this solution  you will not get a Run Out Of Memory Exception   This method retrieves the image orientation   private static final int ROTATION DEGREES   90     This means 512 px private static final Integer MAX IMAGE DIMENSION   512   public static int getOrientation Uri photoUri  throws IOException        ExifInterface exif   new ExifInterface photoUri getPath         int orientation   exif getAttributeInt ExifInterface TAG ORIENTATION  1        switch  orientation            case ExifInterface ORIENTATION ROTATE 90              orientation   ROTATION DEGREES              break          case ExifInterface ORIENTATION ROTATE 180              orientation   ROTATION DEGREES   2              break          case ExifInterface ORIENTATION ROTATE 270              orientation   ROTATION DEGREES   3              break          default                 Default case  image is not rotated             orientation   0             return orientation      Therefore  you would use this method to resize image before load it on memory  In that way  you will not get a Memory Exception   public static Bitmap getCorrectlyOrientedImage Context context  Uri photoUri  throws IOException       InputStream is   context getContentResolver   openInputStream photoUri       BitmapFactory Options dbo   new BitmapFactory Options        dbo inJustDecodeBounds   true      BitmapFactory decodeStream is  null  dbo       is close         int rotatedWidth  rotatedHeight      int orientation   getOrientation photoUri        if  orientation    90    orientation    270            rotatedWidth   dbo outHeight          rotatedHeight   dbo outWidth        else           rotatedWidth   dbo outWidth          rotatedHeight   dbo outHeight             Bitmap srcBitmap      is   context getContentResolver   openInputStream photoUri       if  rotatedWidth  gt  MAX IMAGE DIMENSION    rotatedHeight  gt  MAX IMAGE DIMENSION            float widthRatio     float  rotatedWidth      float  MAX IMAGE DIMENSION           float heightRatio     float  rotatedHeight      float  MAX IMAGE DIMENSION           float maxRatio   Math max widthRatio  heightRatio               Create the bitmap from file         BitmapFactory Options options   new BitmapFactory Options            options inSampleSize    int  maxRatio          srcBitmap   BitmapFactory decodeStream is  null  options         else           srcBitmap   BitmapFactory decodeStream is             is close            if the orientation is not 0  we have to do a rotation      if  orientation  gt  0            Matrix matrix   new Matrix            matrix postRotate orientation            srcBitmap   Bitmap createBitmap srcBitmap  0  0  srcBitmap getWidth                    srcBitmap getHeight    matrix  true              return srcBitmap      This works perfectly for me  I hope this helps somebody else

The first thing you need is the real File path If you have it great  if you are using URI then use this method to get the real Path    public static String getRealPathFromURI Uri contentURI Context context        String path  contentURI getPath        try           Cursor cursor   context getContentResolver   query contentURI  null  null  null  null           cursor moveToFirst            String document id   cursor getString 0           document id   document id substring document id lastIndexOf        1           cursor close             cursor   context getContentResolver   query                  android provider MediaStore Images Media EXTERNAL CONTENT URI                  null  MediaStore Images Media  ID            new String   document id   null           cursor moveToFirst            path   cursor getString cursor getColumnIndex MediaStore Images Media DATA            cursor close              catch Exception e                return path            return path      extract your Bitmap for example     try                               Bitmap bitmap   MediaStore Images Media getBitmap this getContentResolver    selectedImage                                                      catch  IOException e                                                        Log e  IOException  e toString                                 you can use decodeFile   instead if you wish   Now that you have the Bitmap and the real Path get the Orientation of the Image    private static int getExifOrientation String src  throws IOException           int orientation   1           ExifInterface exif   new ExifInterface src           String orientationString exif getAttribute ExifInterface TAG ORIENTATION           try               orientation   Integer parseInt orientationString                     catch NumberFormatException e             return orientation          and finally rotate it to the right position like so   public static Bitmap rotateBitmap String src  Bitmap bitmap            try               int orientation   getExifOrientation src                if  orientation    1                    return bitmap                             Matrix matrix   new Matrix                switch  orientation                    case 2                      matrix setScale -1  1                       break                  case 3                      matrix setRotate 180                       break                  case 4                      matrix setRotate 180                       matrix postScale -1  1                       break                  case 5                      matrix setRotate 90                       matrix postScale -1  1                       break                  case 6                      matrix setRotate 90                       break                  case 7                      matrix setRotate -90                       matrix postScale -1  1                       break                  case 8                      matrix setRotate -90                       break                  default                      return bitmap                             try                   Bitmap oriented   Bitmap createBitmap bitmap  0  0  bitmap getWidth    bitmap getHeight    matrix  true                   bitmap recycle                    return oriented                catch  OutOfMemoryError e                    e printStackTrace                    return bitmap                          catch  IOException e                e printStackTrace                       return bitmap          That s it   you now have the bitmap rotated to the right position   cheers

This is a full solution  found in the Hackbook example from the Facebook SDK   It has the advantage of not needing access to the file itself  This is extremely useful if you are loading an image from the content resolver thingy  e g  if your app is responding to a share-photo intent    public static int getOrientation Context context  Uri photoUri           it s on the external media         Cursor cursor   context getContentResolver   query photoUri              new String     MediaStore Images ImageColumns ORIENTATION    null  null  null        if  cursor getCount      1            return -1             cursor moveToFirst        return cursor getInt 0       And then you can get a rotated Bitmap as follows  This code also scales down the image  badly unfortunately  to MAX IMAGE DIMENSION  Otherwise you may run out of memory   public static Bitmap getCorrectlyOrientedImage Context context  Uri photoUri  throws IOException       InputStream is   context getContentResolver   openInputStream photoUri       BitmapFactory Options dbo   new BitmapFactory Options        dbo inJustDecodeBounds   true      BitmapFactory decodeStream is  null  dbo       is close         int rotatedWidth  rotatedHeight      int orientation   getOrientation context  photoUri        if  orientation    90    orientation    270            rotatedWidth   dbo outHeight          rotatedHeight   dbo outWidth        else           rotatedWidth   dbo outWidth          rotatedHeight   dbo outHeight             Bitmap srcBitmap      is   context getContentResolver   openInputStream photoUri       if  rotatedWidth  gt  MAX IMAGE DIMENSION    rotatedHeight  gt  MAX IMAGE DIMENSION            float widthRatio     float  rotatedWidth      float  MAX IMAGE DIMENSION           float heightRatio     float  rotatedHeight      float  MAX IMAGE DIMENSION           float maxRatio   Math max widthRatio  heightRatio               Create the bitmap from file         BitmapFactory Options options   new BitmapFactory Options            options inSampleSize    int  maxRatio          srcBitmap   BitmapFactory decodeStream is  null  options         else           srcBitmap   BitmapFactory decodeStream is             is close                   if the orientation is not 0  or -1  which means we don t know   we        have to do a rotation              if  orientation  gt  0            Matrix matrix   new Matrix            matrix postRotate orientation            srcBitmap   Bitmap createBitmap srcBitmap  0  0  srcBitmap getWidth                    srcBitmap getHeight    matrix  true              return srcBitmap

Got it to work after many attempts thanks to a post I can no longer find  -   Exif seems to work always  the difficulty was to get the filepath  The code I found makes a different between API older than 4 4 and after 4 4  Basically the picture URI for 4 4  contains  com android providers   For this type of URI  the code uses DocumentsContract to get the picture id and then runs a query using the ContentResolver  while for older SDK  the code goes straight to query the URI with the ContentResolver   Here is the code  sorry I cannot credit who posted it           Handles pre V19 uri s     param context     param contentUri     return     public static String getPathForPreV19 Context context  Uri contentUri        String res   null       String   proj     MediaStore Images Media DATA        Cursor cursor   context getContentResolver   query contentUri  proj  null  null  null       if cursor moveToFirst              int column index   cursor getColumnIndexOrThrow MediaStore Images Media DATA           res   cursor getString column index             cursor close         return res            Handles V19 and up uri s     param context     param contentUri     return path      TargetApi Build VERSION CODES KITKAT  public static String getPathForV19AndUp Context context  Uri contentUri        String wholeID   DocumentsContract getDocumentId contentUri           Split at colon  use second item in the array     String id   wholeID split      1       String   column     MediaStore Images Media DATA            where id is equal to     String sel   MediaStore Images Media  ID             Cursor cursor   context getContentResolver                query MediaStore Images Media EXTERNAL CONTENT URI                      column  sel  new String    id    null        String filePath           int columnIndex   cursor getColumnIndex column 0        if  cursor moveToFirst              filePath   cursor getString columnIndex              cursor close        return filePath     public static String getRealPathFromURI Context context          Uri contentUri        String uriString   String valueOf contentUri       boolean goForKitKat  uriString contains  com android providers          if  Build VERSION SDK INT  gt   Build VERSION CODES KITKAT  amp  amp  goForKitKat                Log i  KIKAT   YES                return getPathForV19AndUp context  contentUri             else                return getPathForPreV19 context  contentUri

You can just read the path from sd card and do the following code   it ll Replace the existing photo after rotating it    Not  Exif doesnt work on most of the devices  it gives the wrong data so it s good to hard code the rotating before saving to any degree you want to You just have to change the angle value in postRotate to any you want to       String photopath   tempphoto getPath   toString        Bitmap bmp   BitmapFactory decodeFile photopath        Matrix matrix   new Matrix        matrix postRotate 90       bmp   Bitmap createBitmap bmp  0  0  bmp getWidth    bmp getHeight    matrix  true        FileOutputStream fOut      try           fOut   new FileOutputStream tempphoto           bmp compress Bitmap CompressFormat JPEG  85  fOut           fOut flush            fOut close           catch  FileNotFoundException e1               TODO Auto-generated catch block         e1 printStackTrace          catch  IOException e               TODO Auto-generated catch block         e printStackTrace

So  as an example     First you need to create an ExifInterface   ExifInterface exif   new ExifInterface filename     You can then grab the orientation of the image   orientation   exif getAttributeInt ExifInterface TAG ORIENTATION  1     Here s what the orientation values mean  http   sylvana net jpegcrop exif orientation html  So  the most important values are 3  6 and 8  If the orientation is ExifInterface ORIENTATION ROTATE 90  which is 6   for example  you can rotate the image like this   Matrix matrix   new Matrix    matrix postRotate 90   rotatedBitmap   Bitmap createBitmap sourceBitmap  0  0  sourceBitmap getWidth    sourceBitmap getHeight    matrix  true     That s just a quick example  though  I m sure there are other ways of performing the actual rotation  But you will find those on StackOverflow as well
