Android - NullPointerException

I'm getting a NullPointerException that is breaking the code on this line:

if (options.isVisible()) {

Here is the block of code:

protected static GoogleMap map;
protected static MarkerOptions markerOptions;
private OnMarkerCreateListener listener;

public LazyMarker(GoogleMap map, MarkerOptions options) {
    this(map, options, null);
}

public LazyMarker(GoogleMap map, MarkerOptions options, OnMarkerCreateListener listener) {
    if (options.isVisible()) {
        createMarker(map, options, listener);
    } else {
        this.map = map;
        this.markerOptions = copy(options);
        this.listener = listener;
    }
}

I'm guessing it has to do with the MarkerOptions variable but I'm not sure if it's breaking because it is not being initialized? Any help would greatly be appreciated.

As @Mzn said Pass a new MarkerOptions() and

You should do a null check there

if (options!=null &&options.isVisible()) {

If you could tell us where you are calling LazyMarker() from and how it looks inside that class, it would be great. I would suggest that you surround the call with a try-catch.

try {
    ...
    marker = new LazyMarker(map, options, listener);
    ...
} catch (NullPointerException e) {
    e.printStackTrace();
}

If this still not works, be sure to check that you are actually defining a MarkerOptions object to the variable.

Hope it helps.

Yes. The runtime told you (by throwing an exception) and now you just got human confirmation. You can initialize MarkerOptions with an empty constructor. Pass a new MarkerOptions() if you don't need to make any customization to the default marker.

See this link for documentation: https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/model/MarkerOptions
