android - MediaStore.Images.Media.getBitmap and out of memory error

Question

My code code is:

public Bitmap loadPhoto(Uri uri) {
    Bitmap scaled = null;
    try {
    scalled = Bitmap.createBitmap(
      MediaStore.Images.Media.getBitmap(getContentResolver(), uri),
      0,0,90, 90);

    if (scaled == null) { return null; }
    } catch(Exception e) { }
    return scaled;
}

After this. I display scaled in ImageView. Every image comes from the device camera.

Every time, I get error: out of memory after I display three photos from camera. How to solve this?

Answer of Praveen Katha will always return null. Here is the updated answer.

Here is the trick, close the input stream after every use. Input Stream means to be used one time. For more information, please follow this answer

private static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
        // Raw height and width of image
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {

            final int halfHeight = height / 2;
            final int halfWidth = width / 2;

            // Calculate the largest inSampleSize value that is a power of 2 and keeps both
            // height and width larger than the requested height and width.
            while ((halfHeight / inSampleSize) >= reqHeight
                    && (halfWidth / inSampleSize) >= reqWidth) {
                inSampleSize *= 2;
            }
        }

        return inSampleSize;
    }

    public static Bitmap decodeSampledBitmapFromUri(Context context, Uri imageUri, int reqWidth, int reqHeight) throws FileNotFoundException {
        Bitmap bitmap = null;
        try {
            // Get input stream of the image
            final BitmapFactory.Options options = new BitmapFactory.Options();
            InputStream iStream = context.getContentResolver().openInputStream(imageUri);

            // First decode with inJustDecodeBounds=true to check dimensions
            options.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(iStream, null, options);
            if (iStream != null) {
                iStream.close();
            }
            iStream = context.getContentResolver().openInputStream(imageUri);

            // Calculate inSampleSize
            options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

            // Decode bitmap with inSampleSize set
            options.inJustDecodeBounds = false;
            bitmap = BitmapFactory.decodeStream(iStream, null, options);
            if (iStream != null) {
                iStream.close();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bitmap;
    }
