Here's an example of the circle approach - first the recording followed by the code.

The radius growth is linear here but is obviously a different function in your example (it slows down as it expands) so you'll need to work with that.

public void pulseCircleTest() {

    // arbitrary point
    LatLng pt = new LatLng(39.171755, -86.510632);

    // move map to point of interest
    CameraPosition cp = CameraPosition.builder().target(pt).zoom(8.0F).build();
    mMap.animateCamera(CameraUpdateFactory.newCameraPosition(cp));

    // create a circle and start animation
    int color = Color.BLUE;
    float initialRadius = 10;
    float maxRadius = 20000f;
    CircleOptions co = new CircleOptions().center(pt).radius(initialRadius).strokeColor(color).fillColor(color).strokeWidth(1.0f);
    Circle c = mMap.addCircle(co);
    Circle c2 = mMap.addCircle(co);

    final Handler h = new Handler();
    h.postDelayed(new Fader(h,c, initialRadius, maxRadius, Color.BLUE, co), 300);
    h.postDelayed(new Fader(h,c2, initialRadius, maxRadius, Color.BLUE, co), 750);
}

private class Fader implements Runnable {
    private float radius, initialRadius, maxRadius;
    private int baseColor, color, initialColor;
    private Handler h;
    private Circle c;
    private float radiusJump = 400;
    int numIncrements, alphaIncrement;
    private CircleOptions co;

    public Fader(Handler h, Circle c, float initialRadius, float maxRadius, int initialColor, CircleOptions co) {
        this.initialRadius = initialRadius;
        this.initialColor = initialColor;
        this.maxRadius = maxRadius;
        this.h = h;
        this.c = c;
        this.co = co;
        reset();
    }

    private void reset() {
        radius = initialRadius;
        this.color = initialColor;
        this.baseColor = initialColor;
        numIncrements = (int)((maxRadius - initialRadius) / radiusJump);
        alphaIncrement = 0x100 / numIncrements;
        if (alphaIncrement <= 0) alphaIncrement = 1;
    }

    public void run() {
        int alpha = Color.alpha(color);
        radius = radius + radiusJump;
        c.setRadius(radius);
        alpha -= alphaIncrement;
        color = Color.argb(alpha, Color.red(baseColor), Color.green(baseColor), Color.blue(baseColor));
        c.setFillColor(color);
        c.setStrokeColor(color);

        if (radius < maxRadius) {
            h.postDelayed(this, 25);
        } else {
            c.remove();
            reset();
            c = mMap.addCircle(co);
            h.postDelayed(this, 2000);
        }

       //done
    }
}

NOTE: This is not the right solution but just a hack to work around .

In your layout take Google map fragment and an ImageView in center

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >

        <fragment
            android:id="@+id/map"
            android:name="com.google.android.gms.maps.SupportMapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:src="@drawable/ic_customerlocation" />
    </RelativeLayout>

now take a gif image of the animation you want and load the gif image into ImageView using Glide or something else

If you want to know the location if user moves the map you can use onCameraIdle() method to get the new location

 @Override
  public void onCameraIdle() {
    if (mGoogleMap != null ) {
        CameraPosition cameraPosition = mGoogleMap.getCameraPosition();
        LatLng latLng = cameraPosition.target;
     }
  }
