How to set blur for brush?
<p>I have been developing the application which draws on a view using user's finger. So, I have a piece of code which demonstrate settings for Paint, Bitmap, Canvas:</p>

<pre><code>    mPaint = new Paint();
    mPaint.setAntiAlias(true);
    mPaint.setDither(true);
    mPaint.setColor(mForegroundColor);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeJoin(Paint.Join.ROUND);
    mPaint.setStrokeCap(Paint.Cap.ROUND);
    mPaint.setStrokeWidth(mBrushWidth);


    mBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    mCanvas = new Canvas(mBitmap);
    mPath = new Path();
    mBitmapPaint = new Paint(Paint.DITHER_FLAG);

    mBitmap.eraseColor(mBackgroundColor);
</code></pre>

<p>But now I need to set a blur for brush, but I don't know how I can do it. I hope you can help me. </p>
