android - how to set camera Image orientation?

Question

In my application I have added feature of image uploading,It works fine with all the Images except camera image,whenever I browse camera image from gallery and portrait image rotate in 90 degree..following is my snippet code..can anyone help me?I followed so many tutorials but all of them work well in kikat..but when same tutorial does not work with ics,jellybean etc..

public class MainActivity extends Activity {
private Button browse;
private String selectedImagePath="";
private ImageView img;

private TextView messageText;

private static int SELECT_PICTURE = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    img = (ImageView)findViewById(R.id.imagevw);
    browse=(Button)findViewById(R.id.browseimg);
    messageText  = (TextView)findViewById(R.id.messageText);
    browse.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
             Intent intent = new Intent();
                intent.setType("image/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
        }
    });
}
 @Override
   public void onActivityResult(int requestCode, int resultCode, Intent data) {
       if (resultCode == RESULT_OK) {
           if (requestCode == SELECT_PICTURE) {
               Uri selectedImageUri = data.getData();

               /*String filePath = getRealPathFromURI(getActivity(), selectedImageUri );
               messageText.setText(filePath );
               Picasso.with(getActivity())
                                      .load(new File(filePath ))
                                      .centerCrop()
                                      .resize(60, 60).into( img);*/

               selectedImagePath = getPath(selectedImageUri);
               messageText.setText(selectedImagePath);
               System.out.println(requestCode);
               System.out.println("Image Path : " + selectedImagePath);
               img.setImageURI(selectedImageUri);
           }
       }
 }

    public String getPath(Uri uri) {
       String[] projection = { MediaStore.Images.Media.DATA };
       Cursor cursor = managedQuery(uri, projection, null, null, null);
       int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
       cursor.moveToFirst();
       return cursor.getString(column_index);
   }

   }

just include this code

public void rotateImage(String file) throws IOException{

    BitmapFactory.Options bounds = new BitmapFactory.Options();
    bounds.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(file, bounds);

    BitmapFactory.Options opts = new BitmapFactory.Options();
    Bitmap bm = BitmapFactory.decodeFile(file, opts);

    int rotationAngle = getCameraPhotoOrientation(getActivity(), Uri.fromFile(file1), file1.toString());

    Matrix matrix = new Matrix();
    matrix.postRotate(rotationAngle, (float) bm.getWidth() / 2, (float) bm.getHeight() / 2);
    Bitmap rotatedBitmap = Bitmap.createBitmap(bm, 0, 0, bounds.outWidth, bounds.outHeight, matrix, true);
    FileOutputStream fos=new FileOutputStream(file);
    rotatedBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    fos.flush();
    fos.close();
}

public static int getCameraPhotoOrientation(Context context, Uri imageUri, String imagePath){
    int rotate = 0;
    try {
        context.getContentResolver().notifyChange(imageUri, null);
        File imageFile = new File(imagePath);
        ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
        int orientation = exif.getAttributeInt(
                ExifInterface.TAG_ORIENTATION,
                ExifInterface.ORIENTATION_UNDEFINED);
        switch (orientation) {
        case ExifInterface.ORIENTATION_NORMAL:
            rotate = 0;
        case ExifInterface.ORIENTATION_ROTATE_270:
            rotate = 270;
            break;
        case ExifInterface.ORIENTATION_ROTATE_180:
            rotate = 180;
            break;
        case ExifInterface.ORIENTATION_ROTATE_90:
            rotate = 90;
            break;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return rotate;
}
