Paint stroke not covering all the side in android

Hi i am creating indicator for doughnut chart but it is covering only three side. Here i added onDraw method.The selected chart index arc should be highlighted with indicator.The indicator should be cover all the four sides.

Code:

@Override
public void draw(Canvas canvas, int x, int y, int width, int height, Paint paint) {
    paint.setAntiAlias(true);
    paint.setStyle(Style.FILL);

    int legendSize = getLegendSize(mRenderer, height / 5, 0);
    int left = x;
    int top = y;
    int right = x + width;
    int sLength = mDataset.getItemCount();
    double total = 0;
    String[] titles = new String[sLength];
    for (int i = 0; i < sLength; i++) {
        total += mDataset.getValue(i);
        titles[i] = mDataset.getCategory(i);
    }
    if (mRenderer.isFitLegend()) {
        legendSize = drawLegend(canvas, mRenderer, titles, left, right, y, width, height, legendSize, paint, true);
    }
    int bottom = y + height - legendSize;

    drawBackground(mRenderer, canvas, x, y, width, height, paint, false, Renderer.NO_COLOR);
    float currentAngle = mRenderer.getStartAngle();
    float labelCurrentAngle = mRenderer.getStartAngle();
    // int mRadius = Math.min(Math.abs(right - left), Math.abs(bottom - top));
    // int radius = (int) (500 * 0.35) + 50;
    //Log.i("radius++", "" + radius);
    int mRadius = Math.min(Math.abs(right - left), Math.abs(bottom - top));
    double rCoef = 0.35 * mRenderer.getScale();
    double decCoef = 0.2 / sLength;
    int radius = (int) (mRadius * rCoef);

    if (mCenterX == 0) {
        mCenterX = (left + right) / 2;
    }
    if (mCenterY == 0) {
        mCenterY = (bottom + top) / 2;
    }

    // Hook in clip detection after center has been calculated
    mPieMap.setDimensions(radius, mCenterX, mCenterY);
    boolean loadPieCfg = !mPieMap.areAllSegmentPresent(sLength);
    if (loadPieCfg) {
        mPieMap.clearPieSegments();
    }

    float shortRadius = radius * 0.9f;
    float longRadius = radius * 1.1f;

    RectF oval = new RectF(mCenterX - radius, mCenterY - radius, mCenterX + radius, mCenterY + radius);
    for (int i = 0; i < sLength; i++) {
        float value = (float) mDataset.getValue(i);
        float angle = (float) (value / total * 360);
        int color = mRenderer.getRenderers().get(i).getColor();

        if (mRenderer.getRenderers().get(i).isClicked()) {
            ClickedArc.CANVAS = canvas;
            ClickedArc.CURRENT_ANGLE = currentAngle;
            ClickedArc.ANGLE = angle;
            ClickedArc.COLOR = color;
            ClickedArc.INDEX = mRenderer.getRenderers().get(i).getDataIndex();
        } else {
