Retrofit and SQlite how to remove lags

I use Retrofit library for getting and parsing JSON from server. All methods I run in MainActivity when Application is starting. And I have trouble when I check is Object(parsed from JSON) already exist in Data Base or not. Application is not responsing. What can I do?

here is methods from MainActivity:

 final MYDBHelperFromApi DBHelperAPI = new MYDBHelperFromApi(this);


        MYapi myapi = (MYapi) new Builder().setLogLevel(LogLevel.FULL).setEndpoint(MYurl.BASE_URL).build().create(MYapi.class);

        myapi.getAsanas(new Callback<Asanas>() {
            public void success(Asanas asanas,
                                Response response) {

                DBHelperAPI.addAsanas(asanas);
                List<Integer> listDB = DBHelperAPI.getAsanasIds();
                DBHelperAPI.checkForDeletedAsanas(asanas, listDB);
                for (AsanaPOJO a : asanas.getAsanas()) {
                    Log.d("AsanaPROGRAM LOGS", BuildConfig.FLAVOR + a.getName());
                }
            }

            public void failure(RetrofitError error) {
                Log.d("FAILURE", "Failure");
            }
        });

        myapi.getPrograms(new Callback<Programs>() {
            @Override
            public void success(Programs programs, Response response) {
                DBHelperAPI.addPrograms(programs);
                for (ProgramPOJO p : programs.getPrograms()) {
                    Log.d("PROGRAMs LOGS", BuildConfig.FLAVOR + p.getName());
                }
            }

            @Override
            public void failure(RetrofitError error) {

            }
        });

and methods from DBhelper:
