I've created a library to do what you are looking for (https://github.com/saulpower/ExpandablePieChart).

      public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         DemoView demoView=new DemoView(getBaseContext());
         setContentView(demoView);
      }

     private class DemoView extends View{
       public DemoView(Context context){
        super(context);
       }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        RectF mBigOval = new RectF(40, 10, 280, 250);
        Paint p = new Paint();
        DashPathEffect dashPath = new DashPathEffect(new float[]{5,5}, (float)1.0);
        PathEffect path=new PathEffect();
        p.setPathEffect(path);
        p.setStyle(Style.FILL_AND_STROKE);
        p.setColor(android.graphics.Color.GREEN);
        canvas.drawArc(mBigOval, 0, 360, true, p);
        p.setColor(Color.RED);

Create your own custom View class and implement the onDraw method to draw the chart using ArcShape.

You can then include your chart component in a layout just as you would one of the built-in components.

Here is an example in Java (not for Android). You could easily port it for Android by using a Canvas instead of Graphics2D object. Instead of fillArc for example, you would use drawArc.
