Change your code to this

    Marker m = getMarker(location);
if(m!= null){
    m.showInfoWindow();
}

The Marker object will be null if the marker has not been rendered on the map yet so be sure to check that the marker object is not null before using it.

For showing infoWindow your marker must be have a title.

 MarkerOptions marker = new MarkerOptions().position(location)
                .icon(BitmapDescriptorFactory.fromBitmap(aBitmapFile))
                .title("The Title"); //here is title
        mapPoint p = new mapPoint(lat, lng);
        googleMap.addMarker(marker);

then you can call: .showInfoWindow(); on your marker.
