Null pointer exceptions in Builders

[levibostian]

I have been using the lib in a couple apps of mine and I have run into NPEs.

In the builder patterns where I am doing companion.getActivity()!!, for example, could have a null activity.

One place in particular I am talking about here is:

            fun runOnUI(run: () -> Unit) {
                companion.getActivity()!!.runOnUiThread {
                    run.invoke()
                }
            }

Where companion.getActivity()!! is causing a NPE. Another way to run on background and UI thread? I would like to call from the thread that was called to me upon, doesn't have to be the UI thread.

I fixed the above issue with companion.getActivity()!! being null via commit: 2aa1368
