How to reverse a Path object?

I have created an arch from a path object like this:

path.addArc(rect, 0f, -180f) //and this draws my path CCW. 

//and if i wanted it drawn CW:
path.addArc(rect, -180f, 180f)//reverse

but i wish i did not have to do this. i wish there was a function like: path.reverse().

I noice there is a path directions class: but i dont see how to use it with Arc.... any idea how i can reverse a path better ?

Instead of revert the arc, you could reverse the step counter of your animation...

pathMeasure = new PathMeasure(yourArcPath, false);

  Matrix mxTransform = new Matrix();
    float eachStepLen = pathMeasure.getLength() / 200; //200 animation steps
    if (currentStep <= 110 && !reverseActive) {

        currentStep ++; // --- Going forward...

        pathMeasure.getMatrix(
                eachStepLen * currentStep,
                mxTransform,
                PathMeasure.POSITION_MATRIX_FLAG);

        canvas.drawBitmap(image, mxTransform, null);


    } else {
        reverseActive = true;

        pathMeasure.getMatrix(
                eachStepLen * currentStep,
                mxTransform,
                PathMeasure.POSITION_MATRIX_FLAG);

        canvas.drawBitmap(image, mxTransform, null);

        currentStep --; // --- Going backwards...

        if (currentStep == 0){
            reverseActive = !reverseActive;
        }

    }
