Answer 1

This happens to be a bug in earlier versions of Android.

I solved this issue just getting the orientation angle and rotate the bitmap accordingly.

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;
    }
}

Answer 2

Also query the MediaStore.Images.Media.ORIENTATION value to get the rotation angle. Then you can rotate the image by yourself or whatever.

Answer 3

What I am doing : first check the orientation of image taken by camera using its meta data information , and If we found this in portrait then we have to rotate the image by 90 and display otherwise only display.

For getting the Information about orientation of image we can use ExifInterface. That's It!
