Reduce size of Bitmap to some specified pixel in Android

If you pass bitmap width and height then use:

public Bitmap getResizedBitmap(Bitmap image, int bitmapWidth, int bitmapHeight) {    return Bitmap.createScaledBitmap(image, bitmapWidth, bitmapHeight, true);}

If you want to keep the bitmap ratio the same, but reduce it to a maximum side length, use:

public Bitmap getResizedBitmap(Bitmap image, int maxSize) {        int width = image.getWidth();        int height = image.getHeight();        float bitmapRatio = (float) width / (float) height;        if (bitmapRatio > 1) {            width = maxSize;            height = (int) (width / bitmapRatio);        } else {            height = maxSize;            width = (int) (height * bitmapRatio);        }        return Bitmap.createScaledBitmap(image, width, height, true);}

Use this Method

 /** getResizedBitmap method is used to Resized the Image according to custom width and height   * @param image  * @param newHeight (new desired height)  * @param newWidth (new desired Width)  * @return image (new resized image)  * */public static Bitmap getResizedBitmap(Bitmap image, int newHeight, int newWidth) {    int width = image.getWidth();    int height = image.getHeight();    float scaleWidth = ((float) newWidth) / width;    float scaleHeight = ((float) newHeight) / height;    // create a matrix for the manipulation    Matrix matrix = new Matrix();    // resize the bit map    matrix.postScale(scaleWidth, scaleHeight);    // recreate the new Bitmap    Bitmap resizedBitmap = Bitmap.createBitmap(image, 0, 0, width, height,            matrix, false);    return resizedBitmap;}

or you can do it like this:

Bitmap.createScaledBitmap(Bitmap src, int dstWidth, int dstHeight, boolean filter);

Passing filter = false will result in a blocky, pixellated image.

Passing filter = true will give you smoother edges.
