I am adding a custom marker to the android map view. here is the image I am using for it.It looks like as more markers are placed say about 100 the entire app is getting slow. H

It's possible, but looks like does not make sense. Because Google Map requires only bitmap. So you need create bitmap and draw your shape with help of canvas.

marker.xml

dimen.xml

    4dp
    40dp
    32dp

part of code to convert shape into bitmap (from fragment/activity with Map)

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;
    Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.marker, null);
    Canvas canvas = new Canvas();
    int width = getResources().getDimensionPixelOffset(R.dimen.marker_width);
    int height = getResources().getDimensionPixelOffset(R.dimen.marker_height);
    drawable.setBounds(0, 0, width, height);
    Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    canvas.setBitmap(bitmap);
    drawable.draw(canvas);
    BitmapDescriptor bitmapDescriptor = BitmapDescriptorFactory.fromBitmap(bitmap);
    LatLng sydney = new LatLng(-34, 151);
    mMap.addMarker(new MarkerOptions().icon(bitmapDescriptor).position(sydney).title("Marker in Sydney"));
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}

result would be next
