This is my code:
PSTrip psTrip = JsonUtil.jsonToObject(jsonObject.toString(), PSTrip.class);
int size = psTrip.getTripSteps().size()-1;
RealmList<Step> steps = psTrip.getTripSteps().get(size).getSteps();
RealmList<TripStep> tripSteps = psTrip.getTripSteps();
Log.i("","continue init after getting tripsteps and steps");
if(tripSteps.size() > 0) {
Log.i("","continue init blabla");
for (int i = 0; i < tripSteps.size(); i++) {
RealmList<Step> mergedSteps = Utils.getMergedSteps(context, tripSteps.get(i).getRoute().getSteps());
tripSteps.get(i).getRoute().getSteps().clear();
for (Step step : mergedSteps) {
tripSteps.get(i).getRoute().getSteps().add(step);
}
}
Log.i("", "continue init after for in which I merge the steps for the tripsteps");
steps = Utils.getMergedSteps(context, steps);
Log.i("", "continue init after merging the steps");
tripSteps.get(size).setSteps(steps);
Log.i("", "continue init after settting steps on tripsteps");
psTrip.setTripSteps(tripSteps);
}
PSTripDBFactory.getInstance(context).addToList(psTrip);
The Utils.getMergedSteps just takes the list of steps (Step from Google maps class), and if it is possible, it merges them.
My problem is at the last line which does:
public void addToList(PSTrip psTrip){
try{
PSTrip insideAlready = getListOfCompletedTripsByID(psTrip.getId());
Log.i("","continue init inside already:" + insideAlready);
if(insideAlready == null){
Log.i("","continue init will copy to realm");
realm.beginTransaction();
realm.copyToRealm(psTrip);
realm.commitTransaction();
Log.i("","continue init will copy to realm finished");
}else{
Log.i("","continue init will copyorupdate to realm");
realm.beginTransaction();
realm.copyToRealmOrUpdate(psTrip);
realm.commitTransaction();
Log.i("","continue init will copyorupdate to realm finished");
}
}catch (Exception e){
Log.i("","continue init error trying to add to realm" + e.getMessage());
realm.cancelTransaction();
}
}
Where getListOfCompletedTripsByID is the following function:
public PSTrip getListOfCompletedTripsByID( String id){
RealmResults<PSTrip> completed = realm.where(PSTrip.class).equalTo("id" , id).findAll();
if(completed.size() > 0){
return completed.get(0);
}else{
return null;
}
}
I get back the following error response:

Does anyone have an ideea why does realm return me a "table has no columns" error?

In my fragment, if I do
private RealmChangeListener<RealmResults<Customer>> customerRealmChangeListener;
RealmResults<Customer> customerRealmResults;
Realm realm = Realm.getDefaultInstance();
customerRealmChangeListener = customers -> {
customers.forEach(customer -> {
Log.w("CUSTOMERS", customer.getCustomerName());
});
};
customerRealmResults = realm.where(Customer.class).equalTo("invoices.deliveryStatus", 0).findAllAsync();
customerRealmResults.addChangeListener(customerRealmChangeListener);
realm.executeTransactionAsync(transactionRealm -> {
Customer newCustomer = new Customer(1, 1, "Test Customer 1");
Invoice newInvoice1 = new Invoice(new TtInvoice(1234, 20/02/2023, "10:07:00", 1, 0));
Invoice newInvoice2 = new Invoice(new TtInvoice(2468, 20/02/2023, "10:08:00", 1, 1));
newCustomer.getInvoices().add(newInvoice1);
newCustomer.getInvoices().add(newInvoice2);
transactionRealm.insert(newCustomer);
});
No issues with the adding, the problem I am having is the 'findAllAsync', it returns both invoices instead of only the 1.
I get the customer back as I would expect, but a call to 'customer.getInvoices()' returns 2 invoices instead of just 1.
I feel like what I am trying to do is super simple and I'm just not seeing the problem, have been trying to figure this out for a couple of days now to no avail.
If I set a breakpoint on the findAllAsync() call and run my own 'findAll()' using the same query, it has the same issue.
Maybe it is how I am adding new invoices, not 100% sure on that one though.
Otherwise I am liking Realm a hell of a lot better than Room.

My intention is to get the JSON Array item and display title,price,pic,detail_url from it. I found out how to display it one at a time so far, but couldn't find how to iterate the JSON object so that I can display the data in a listview. Please help, I am new to this and I've been stuck for quite awhile now. If you want to see my interface, retrofit instance etc just let me know.
private void taobaoSearch(){
TaobaoInterface retrofitInterface = RetrofitInstance.getRetrofitInstanceTaobao().create(TaobaoInterface.class);
Call<TaobaoModel> listCall = retrofitInterface.getTaobao("item_search", "40","default", "iphone","taobao-api.p.rapidapi.com", "//apikey hidden");
listCall.enqueue(new Callback<TaobaoModel>() {
#Override
public void onResponse(Call<TaobaoModel> call, Response<TaobaoModel> response) {
List<Result> retro=response.body().getitems();
generateDataList(retro);
}
#Override
public void onFailure(Call<TaobaoModel> call, Throwable t) {
System.out.println("FAILED");
System.out.println(call);
t.printStackTrace();
}
});
}
/*Method to generate List of data using RecyclerView with custom adapter*/
private void generateDataList(List<Result> dataList) {
recyclerView = findViewById(R.id.customRecycler);
adapter = new CustomAdapter(this,dataList);
recyclerView.setAdapter(adapter);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
}
I am trying to access getter property of the pojo received in the response, but there is no such option.so is there any other way, I can do that?
The code for that call is as below:
results.subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<GenericResponse<List<FoodTruck>>>() {

Now Basically I want to acess someting like response.getData().... But there is no such option.
Possibly data not accessible, because it is private. Try to crete getter method.
public class GenericResponse<T> {
#JsonProperty("status")
private String status;
#JsonProperty("message")
private String message;
#JsonProperty("data")
private T data;
public T getData() {
return data;
}
}

put your get,set method yourself.
I have an object which I for now save using SharedPreferences like this:
public String getActiveTripString(Context con) {
return preferences.getString(ACTIVE_TRIP, "-1");
}
public void setActiveTripString(Context context, String string) {
setString(context, string, ACTIVE_TRIP);
}
public PSTrip getActiveTrip(Context context) {
String active = getActiveTripString(context);
PSTrip psTrip = null;
if (active.contentEquals("-1")) {
return null;
} else {
try{
psTrip = JsonUtil.jsonToObject(active, PSTrip.class);
}catch (Exception e){
Log.i("","getActiveTrip error is:" + e.getMessage());
}
return psTrip;
}
}
public void setActiveTrip(PSTrip psTrip, Context context) {
try{
setActiveTripString(context, JsonUtil.objectToJson(psTrip, PSTrip.class));
}catch (Exception e){
Log.i("","setActiveTrip error is:" + e.getMessage());
}
}
Where I have function as you can see, that create a json and then save it as a string in SharedPrefferences. But The object is BIG, and the more I add into it, the app start to be more laggy until it's unresponsive.
I also need to use this object in a lot of places, so I always need to call:
GetActiveTrip to get it, make my modifications, then SetActiveTrip to save it.
I'm looking for a more efficient way to save it. I tried with REALM, to save it in a database, but because my object is so big, and modified in a lot of places, I did not quite manage to make it work, Having to call Realm a lot just to add items in the database, in order to have managed database items, so I can add them in my object, and so on. Which also I think might be memory consuming. And It crashes a lot with realm exceptions.
Any other way I could do this? Is saving to a file more efficient than to Shared Preferences? As I saw in Android Monitor, analysing my traces, the GSON function that creates the JSON takes a lot of resources.
Any suggestions what I could use?
EDIT: My object:

Where: Route, Destination are the google maps object, if you are familiar with them, you know what they include and their size;
TripStep = similar with the STEP object from google BUT, it includes 2 arrays:
private RealmList<StopInfo> filteredLocations = new RealmList<>();
private RealmList<StopInfo> rawLocations = new RealmList<>();
In which I have to add a new location every 5-6 seconds in the rawLocations.
Add a new location each time the rawlocation I get is farther than x metres from the last rawLocation I got.
Getting the Object from Preferences, deserialising, getting the latest TripStep and adding the new Location to the filteredLocations and rawLocations seems to take a log of memory. So This is what I think is the problem
After all, I chose to use Realm, instead of shared preferences, it's more efficient, and even if I still have some issues with the changes I make to my file, I'm getting to a stable version quickly.
It has it's downsides (some REALM objects are not serialised correctly by GSON, and you will need to use jackson, and also not being able to use functions inside your model, or that it supports just primitives is a big issue with it, but if you manage to go over this, it's worth it)
Would not suggest adding Realm database to a project that is already big
