How View.invalidate() is processed in Android

This document is based on the code of android-4.1.1_r6 (Jelly Bean).

First, the invalidate() call will be propagated back to the root of the view hierarchy. During the propagation, the system determines the dirty area that needs to be redrawn. The propagation will eventually reach ViewRootImpl.

/*
Calculates the estimated brightness of an Android Bitmap.
pixelSpacing tells how many pixels to skip each pixel. Higher values result in better performance, but a more rough estimate.
When pixelSpacing = 1, the method actually calculates the real average brightness, not an estimate.
This is what the calculateBrightness() shorthand is for.
Do not use values for pixelSpacing that are smaller than 1.

public int calculateBrightnessEstimate(android.graphics.Bitmap bitmap, int pixelSpacing) {
	int R = 0; int G = 0; int B = 0;
	int height = bitmap.getHeight();

What is this

This gitst contains a script to push Android libraries as artifacts on a maven repository using the gradle build system.

It is somewhate a fork of Chris Banes gradle push script.

This was me while trying to understand how to setup maven publishing with gradle:

Documentation is absent or very lacking and I found no script handling javadoc properly for Android.
