Custom curved lines in Android

I am working on a game where I have some bezier curves. At the moment, everything is fine and it's working as it should, although I do some complicated operation on this curves. To draw the curves I use a canvas and paths, like this:

private void refresh() {
    mPath = new Path();
    mPath.moveTo(start_x, start_y);
    mPath.cubicTo(anchor1_x, anchor1_y, anchor2_x, anchor2_y, end_x, end_y);
}
public void draw(Canvas canvas, Paint paint) {
    Path newPath = new Path(mPath);
    Matrix mMatrix = new Matrix();
    mMatrix.setTranslate(-mCamera.x1, -.mCamera.y1);
    mMatrix.postScale(mCamera.getWidthRatio(), mCamera.getHeightRatio());
    newPath.transform(mMatrix);
    canvas.drawPath(newPath, paint);
}

The paint parameter is ussually the following one:

 curvesPaint = new Paint();
 curvesPaint.setColor(0xFFFFFFFF);
 curvesPaint.setAntiAlias(true);
 curvesPaint.setStrokeCap(Paint.Cap.ROUND);
 curvesPaint.setStrokeJoin(Paint.Join.ROUND);
 curvesPaint.setStyle(Paint.Style.STROKE);
 curvesPaint.setStrokeWidth(canvas.getHeight() / 100f);
 if (shadow)
      curvesPaint.setShadowLayer(canvas.getHeight() / 50f, 0, 0, 0xAAFFFFFF);
 else
     curvesPaint.setShadowLayer(0, 0, 0, 0xAAFFFFFF);

My question is: how can I make the curves more beautiful? At the moment, they're only white (or white with a white shadow). I want to be able to draw them with a nice gradient or model on them and I have no idea how to do that. I was thinking about the setShader function of the Paint class but I don't know if I can use it for my purpose or how to use it. Other solutions, like drawing multiple paths one above the other, is clearly impractical due to low fps.
