Crashes LazyMarker.java #32

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem? Please provide sscce (short, self
contained, correct example) when possible.
Use LazyMarker.java's LatLng getPosition() method without try/catch statements.

What is the expected output? What do you see instead?
Exceptions should be gracefully handled.  Instead the app crashes!!!

What is the exception?

What is the code that uses LazyMarker?

~"What is the exception?"
I am not able to reproduce it now.  But at least I don't have to worry about my 
app crashing...

~"What is the code that uses LazyMarker?"
There is a whole chain of calls within android-maps-extensions.  That 
particular getPosition() method is not called by my external project.  I would 
have to dig through many calls to get to the bottom of it.  This is irrelevant, 
exception checking is a must here.

If that's from inside the lib and you are not creating LazyMarkers yourself, 
then I suspect this might be after you call Marker.remove(), which makes 
underlaying LazyMarker unusable in any way. After that, when 
Marker.getPosition() is called for any reason, it throws NPE. Stacktrace would 
help seeing if that's a memory leak in the lib.
Also, which version of the library are you using?

I am using the latest version of your library (from Google Drive).

I know this stacktrace isn't pointing to getPosition(), but it is a similar 
deal.  Just needs good exception handling.

The question here is why GoogleMap.addMarker throws an exception.

I guess this can be for many reasons.

Make sure your icon is a PNG file and also you have set position in 
MarkerOptions.
