Decode an immutable bitmap from the specified byte array.

Usage

From source file:Main.java

public static Bitmap decodeSampledBitmapFromData(byte[] data) {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;/* ww  w . j  a  v a 2  s  . com*/

    options.inSampleSize = 1; // saved image will be one half the width and
    // height of the original (image captured is
    // double the resolution of the screen size)
    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeByteArray(data, 0, data.length, options);
