Use BitmapFactory.Options to save image without oom error like below.

final int DESIRED_WIDTH = 640;

// Set inJustDecodeBounds to get the current size of the image; does not
// return a Bitmap
final BitmapFactory.Options sizeOptions = new BitmapFactory.Options();
sizeOptions.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(data, 0, data.length, sizeOptions);
Log.d(TAG, "Bitmap is " + sizeOptions.outWidth + "x"
            + sizeOptions.outHeight);

// Now use the size to determine the ratio you want to shrink it
final float widthSampling = sizeOptions.outWidth / DESIRED_WIDTH;
sizeOptions.inJustDecodeBounds = false;
// Note this drops the fractional portion, making it smaller
sizeOptions.inSampleSize = (int) widthSampling;
Log.d(TAG, "Sample size = " + sizeOptions.inSampleSize);

// Scale by the smallest amount so that image is at least the desired
// size in each direction
final Bitmap result = BitmapFactory.decodeByteArray(data, 0, data.length,
        sizeOptions);
