ReactNative OneSignal Android failed to compile RNOneSignal.java because bunch of unhandled JSONException

If you compile ReactNative Android OneSignal plugin and hit the unhandled

JSONException that thrown or triggered by 

callback.invoke(RNUtils.jsonToWritableMap(outcomeEvent.toJSONObject()));

Simply add this:
-- callback.invoke(RNUtils.jsonToWritableMap(outcomeEvent.toJSONObject()));

++ try {

++     callback.invoke(RNUtils.jsonToWritableMap(outcomeEvent.toJSONObject()));

++ }

++ catch (JSONException je ) {

++     je.printStackTrace();

++     return;

++ }

Hope it help ^^
