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?

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

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.

adapter = new CustomAdapter(this,dataList);
recyclerView.setAdapter(adapter);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);

}
I have set switch box in adapter when switch box is enable then open custom check box list item. I have select check box item multiple. This switch box design when select spinner item and then open fragment page. When select multiple check box item and send JSON param like this:
"attendees": [
{
"id": "1",
"person": "xza"
},
{
"id": "2",
"person": "cfd"
}
]
And send button applying in activity. Spinner and save button design in activity and select item design in fragment.

JsonObject obj = new JsonObject();
obj.addProperty("id", attendee.getId());
obj.addProperty("name", attendee.getName());
jsonArray.add(obj);
}
}
return jsonArray;

I expect the output is:
"attendees":[{"id":"1","person":"fff"},{"id":"2","person":"dfdf"}]
But the actual output is:
"attendees": []
My Data Structure
My object has multiple ArrayLists and primitives.
On retrieving, I get this error Expected a List while deserializing, but got a class java.util.HashMap .
I understand I'm getting this error because that is how Firebase stores it.
I just have never worked with these many fields.
My question is can I convert it to my object directly?
malhobayyeb pointed this here https://stackoverflow.com/a/35979715/9860553 which seems pretty close to my case, but the answer he suggested is not working
I'm attaching my Objects structure too.
Though I think the code is not needed.
The issue is simply "in firebase, How to handle data if the list is inside another object "

Edit 1
The code is changed now. I've achieved what I wanted FOR NOW in a very caveman way, using the answer in the link above. But that leaves the code useless for future updates.
My original code was a straightforward valueEventListener. nothing special really. nothing at all.
businessData = dataSnapshot.getValue(BusinessData.class);
the refernece is pointing to the right location too
mRef = database.getReference(Common.id).child("bizData");
I want to use two class for database.
here is my source.
public class UserInfo extends RealmObject {
private String user_email;
private String nick_name;
private String expected_date;
private boolean initial_autho;
private int resultDay;
public int getResultDay() {
return resultDay;
}
public void setResultDay(int resultDay) {
this.resultDay = resultDay;
}
public String getUser_email() {
return user_email;
}
public void setUser_email(String user_email) {
this.user_email = user_email;
}
public String getNick_name() {
return nick_name;
}
public void setNick_name(String nick_name) {
this.nick_name = nick_name;
}
public String getExpected_date() {
return expected_date;
}
public void setExpected_date(String expected_date) {
this.expected_date = expected_date;
}
public boolean getInitial_autho() {
return initial_autho;
}
public void setInitial_autho(boolean initial_autho) {
this.initial_autho = initial_autho;
}
}
public class Calendar extends Realmobject {
private long millis;
private String note; // 노트
private String mail; // who
private int image; // image resource
public String getMail() {
return mail;
}
public void setMail(String mail) {
this.mail = mail;
}
public long getTime() {
return millis;
}
public String getNote() {
return note;
}
public int getImage() {
return image;
}
public void setDate(long time) {
this.millis = time;
}
public void setNote(String note) {
this.note = note;
}
public void setImage(int image) {
this.image = image;
}
}
How do I use these things in Activity?
I don't know exactly and I much appreciate if you guys could tell about that more specifically as much as you can.
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:
03-18 11:14:56.135 21908-21908/nl.hgrams.passenger I/﹕ continue init after for in which I merge the steps for the tripsteps

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

The rest are mostly google maps classes.
The PSTrip RealmList messages is empty.
the Route class contains a RealmList which is not empty (thats why I try doing copy to realm on it before)
