Usage

From source file:Main.java

public static Bitmap getScaledScreenshot(final Activity activity, int scaleWidth, int scaleHeight,
        boolean relativeScaleIfTrue) {

    // We could get a null or zero px bitmap if the rootView hasn't been measured
    // appropriately, or we grab it before layout.
    // This is ok, and we should handle it gracefully.
    final Bitmap original = rootView.getDrawingCache();
    Bitmap scaled = null;
    if (null != original && original.getWidth() > 0 && original.getHeight() > 0) {
