I doubt this is an issue in rx-preferences or even GSON. You only had 44kb of memory left. Something else in your application is using up this memory.

from rx-preferences.

But I am getting this OutOfMemoryError only GsonConverter.serialize(), this method used for RxSharedPreferences
@singleton
@provides
public Preference provideTokenPref(RxSharedPreferences rxSharedPreferences, Gson gson) {
return rxSharedPreferences.getObject(AppConstants.AUTH_TOKEN, new LoginResponse(), new GsonConverter(gson, LoginResponse.class));
}
