Object would be serialized to `null` issue

[sayed19]

I have a sign up option for my application where i call a custom method which upload the user information to the meteor server. It was working flawlessly. Suddenly it is no longer working. My app is crashing whenever I try to sign up. It is throwing an error "Object would be serialized to null". I believe it is something to do with the 'send' method of the ddp. How do I overcome this problem. Have anyone faced it before. Please shed some light as early as possible.

Thanks for your report!

Now that you closed the issue, could you explain what was wrong here? Has this been a bug in this library? Or has there been something you could fix in your application code?

Thank you!

I just had the same problem :smiley: The reason was this code:

...
Object[] args={new UpdatePositionObject(location.getLatitude(),location.getLongitude())};
mMeteor.call(methodeName,args);
...

class UpdatePositionObject{
    private final double lat;
    private final double lng;

    public UpdatePositionObject(double lat, double lng){
       this.lat=lat;
        this.lng=lng;
    }
}

After i changed the call to this: mMeteor.call(methodeName,new Object[] { location.getLatitude(),location.getLongitude() }); it works like a charm. :+1:

Thanks for explaining what was the issue here, @renehauck!

Since this issue stems from problems with the data types again, I've added some notes about the available data types to the README: https://github.com/delight-im/Android-DDP/commit/af8e26c633e3372cea43acab797c4c5b6552e793
