Hi.
I have been using your very cool library, and it has been doing great, but lately, for security reasons, I needed to turn auto backup off from the manifest.
Unfortunately, when changing to android:allowBackup="false" I get the following error:

Manifest merger failed : Attribute application@allowBackup value=(false) from AndroidManifest.xml:78:9-36
is also present at [com.bcgdv.asia.lib:connectpattern:0.3] AndroidManifest.xml:12:9-35 value=(true).
Suggestion: add 'tools:replace="android:allowBackup"' to element at AndroidManifest.xml:76:5-353:19 to override.

Is it possible to remove the allowBackup flag from the manifest of the library?

Note: actually, tools:replace="android:allowBackup" in the application block solves the issue, but it's less pretty.

Thanks

Hi.
Great engine. Correctly engineered. Just one thing: Can you please make the thresholds of the proximity to dots more conservative?
It is a bit frustrating to draw a diagonal around a point.

Thanks.

/**
 * Setup circles on a screen
 */
private void drawLineToTouchPoint(Canvas canvas) {
    if (touchPoint.height() > 0 && touchPoint.width() > 0) {
        drawLine(canvas, circles[connectionOrder.get(connectionOrder.size() - 1)], touchPoint);
    }
}

Forgot to check that !connectionOrder.isEmpty()
It may crash if the view refreshes when you your finger on, and it's blank.

How to make to save the pattern and open a page with it?
