You can use this: Decode the resource and pass it to this function with scalingfactor

public static Bitmap ScaleBitmap(Bitmap bm, float scalingFactor) {
    int scaleHeight = (int) (bm.getHeight() * scalingFactor);
    int scaleWidth = (int) (bm.getWidth() * scalingFactor);
    return Bitmap.createScaledBitmap(bm, scaleWidth, scaleHeight, true);
}

for scaling factor refer to this Scale factor for xxhdpi android?
