Using library in a mobile app

[sofiaantonova]

Hello there! I`m trying to create a mobile app working with your library, and it always throws "Attempt to read from field 'com.google.gson.JsonObject io.github.fastily.jwiki.core.WQuery$QReply.input' on a null object reference in method 'void io.github.fastily.jwiki.core.Wiki.refreshNS()'" as i initialize wiki with "Wiki wiki = new Wiki.Builder().build();". Well, actually it works on a PC, but fails on a mobile platform. Can you help me with some ideas to solve, please?
