try this!

private int fps = 0, ifps = 0;
@Override
protected void onDraw(Canvas canvas) {
    long now = System.currentTimeMillis();

    // perform other operations

    System.out.println("FPS:" + fps);

    ifps++;
    if(now > (mLastTime + 1000)) {
        mLastTime = now;
        fps = ifps;
    ifps = 0;
    }
}
