Answer

In Volley, onResponse and onErrorResponse is called on UI thread. So please move you parsing logic into parseNetworkResponse (as this is done in background thread) or you can use Executors (or ExecutorServices depending on your use case) or AsyncTask to switch the threads once you receive the response in OnResponse and save the data in the local DB like shown below.

public void onResponse(JSONObject response) {
     Executor executor = Executors.newSingleThreadExecutor();
     executor.execute(() -> 
        // your database code 
     );       
}

or

public void onResponse(JSONObject response) {
     AsyncTask.execute(new Runnable() {
        public void run() {
           // your database code 
       }
    });      
}
