Capture photo rotate 90 degree in samsung mobile

Question

Photo is rotating 90 degree while capturing from camera in samsung mobile rest of other mobiles(HTC) its working fine. Please help me for this.

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, IMAGE_CAPTURE); 

@Override 
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {     
    super.onActivityResult(requestCode, resultCode, data);    
      try
    {
    if (requestCode == IMAGE_CAPTURE) {
       if (resultCode == RESULT_OK){

       Uri contentUri = data.getData();
       if(contentUri!=null)
       {
        String[] proj = { MediaStore.Images.Media.DATA };         
            Cursor cursor = managedQuery(contentUri, proj, null, null, null);         
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);         
        cursor.moveToFirst();         
        imageUri = Uri.parse(cursor.getString(column_index));
       }

       tempBitmap = (Bitmap) data.getExtras().get("data"); 
       mainImageView.setImageBitmap(tempBitmap);
       isCaptureFromCamera = true;
    }
 }

Some device rotate image according to device orientation .

here i have write one common method to get orientation and get image in right scale

    public  Bitmap decodeFile(String path) {//you can provide file path here 
        int orientation;
        try {
            if (path == null) {
                return null;
            }
            // decode image size 
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            // Find the correct scale value. It should be the power of 2.
            final int REQUIRED_SIZE = 70;
            int width_tmp = o.outWidth, height_tmp = o.outHeight;
            int scale = 0;
            while (true) {
                if (width_tmp / 2 < REQUIRED_SIZE
                        || height_tmp / 2 < REQUIRED_SIZE)
                    break;
                width_tmp /= 2;
                height_tmp /= 2;
            scale++;
            }
            // decode with inSampleSize
            BitmapFactory.Options o2 = new BitmapFactory.Options();
            o2.inSampleSize = scale;
            Bitmap bm = BitmapFactory.decodeFile(path, o2);
            Bitmap bitmap = bm;

            ExifInterface exif = new ExifInterface(path);

            orientation = exif
                    .getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);

            Log.e("ExifInteface .........", "rotation ="+orientation);

//          exif.setAttribute(ExifInterface.ORIENTATION_ROTATE_90, 90);

            Log.e("orientation", "" + orientation);
            Matrix m = new Matrix();

            if ((orientation == ExifInterface.ORIENTATION_ROTATE_180)) {
                m.postRotate(180);
//              m.postScale((float) bm.getWidth(), (float) bm.getHeight());
                // if(m.preRotate(90)){
                Log.e("in orientation", "" + orientation);
                bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),
                        bm.getHeight(), m, true);
                return bitmap;
            } else if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {
                m.postRotate(90); 
                Log.e("in orientation", "" + orientation);
                bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),
                        bm.getHeight(), m, true);
                return bitmap;
            }
            else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {
                m.postRotate(270);
                Log.e("in orientation", "" + orientation);
                bitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(),
                        bm.getHeight(), m, true);
                return bitmap;
            } 
            return bitmap;
        } catch (Exception e) {
            return null;
        }

    }

EDIT:

This code is not optimized , i just show the logic code from my one of the test project.

Another thing you can add to the above solutions is "samsung".contentEquals(Build.MANUFACTURER). If you know that your problem is only with Samsung devices you could be reasonably sure that you need to rotate the image returned (only) if ("samsung".contentEquals(Build.MANUFACTURER) && getActivity().getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT // && width > height//) // here you know you need to rotate

You could be "reasonably" confident that the rotation is warranted then.
