I not found that method? Can u help me.

tinydb.putList("MyUsers", mUsersArray);

Can I use only one Instance of TinyDB to Store all of data? or do i have to create multiple to store multiple data

i used the putImage to save and image into TinyDB with the parameters but getting the image does not seem to work or am i doing something wrong
saving the image
private void saveImage() { tinyDB.putImage("Splanner/profile","profilepic.png", photo); }
getting the image
Bitmap getImage = tinyDB.getImage("Splanner/profile"); userDp.setImageBitmap(getImage);

Hello, what do I add to dependencies to use this library?

Hello,

I really loved your library, it helped me testing some features in my prototype.

But, using maps in Kotlin, I had some difficulties trying to get the map automatically filled. After some time trying to make things work, I remembered that Gson has a TypeToken interface that solved cases like that.

Originally I did this as an issue on mukeshsolanki/easypreferences#4, but I thought it would be correct to share this change with your project too as it served as a basis for him, so I will make a PR for it.

I store the following object in TinyDB:

import java.io.Serializable;


public class Image implements Serializable{
    private String name;
    private String small, medium, large;
    private String timestamp;

    public Image() {
    }

    public Image(String name, String small, String medium, String large, String timestamp) {
        this.name = name;
        this.small = small;
        this.medium = medium;
        this.large = large;
        this.timestamp = timestamp;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSmall() {
        return small;
    }

    public void setSmall(String small) {
        this.small = small;
    }

    public String getMedium() {
        return medium;
    }

    public void setMedium(String medium) {
        this.medium = medium;
    }

    public String getLarge() {
        return large;
    }

    public void setLarge(String large) {
        this.large = large;
    }

    public String getTimestamp() {
        return timestamp;
    }

    public void setTimestamp(String timestamp) {
        this.timestamp = timestamp;
    }
}

I can retrieve the object like this:
ArrayList<Object> img_aux = tinydb.getListObject("Favorites", Image.class);

Could I look for a SPECIFIC STRING within the Favorites key?

How to delete the object class values.
I use this in putobject.
fun putObject(key: String, value: Any, context: Context) {
TinyDB(context).putObject(key, value)
}

but I need to delete also the object.

This class was deprecated in API level 29.
Use the AndroidX Preference Library for consistent behavior across all devices. For more information on using the AndroidX Preference Library see Settings.
https://developer.android.com/reference/android/preference/PreferenceManager

Any solutions to this?

Hello,

i have a problem that i could not resolve.
i have my custom class "Article" and want to put an Article ArrayList.

public class Article extends Object 

This problem explains all... :x

ArrayList<Article> list = new ArrayList<Article>();
list.add(new Article(1,"ok", "ok", "ok"));
list.add(new Article(1,"ok", "ok", "ok"));
list.add(new Article(1,"ok", "ok", "ok"));
list.add(new Article(1,"ok", "ok", "ok"));
a.putObject("je", list.get(1)); // It works well
a.putListObject("tu", list); // It doesn't fuck*** work. Why ? :x

Your methods

public void putObject(String key, Object obj) // Object 
public void putListObject(String key, ArrayList<Object> objArray) // and Object... 
// Why it doesn't like Arraylist ? 

Thank you for your time.

I think that lastImagePath should be static.
Since it is the last, it doesn't matter which instance of the TinyDB it is.
Also, it is not really used so you can delete it...

fun insertFood(item: FoodDomain){

    listFood = tinyDB.getListObject("CartList")
    listFood.add(item)
    tinyDB.putListObject("CartList",listFood)
    var fod : FoodDomain = listFood.get(0)
    }

The error is: when i get the list, it have size, 1 or 2 or 3 , is normal; but if i want get one object of the list, it say "must not be null"

like IS A LIST WITH SIZE BUT ALL OBJECT ARE NULL OR NOT EXIST ? please help :c i have this problem 2 months

how to use ..

public Object getObject(String key, Class<?> classOfT){

    String json = getString(key);
    Object value = new Gson().fromJson(json, classOfT);
    if (value == null)
        throw new NullPointerException();
    return value;
}

this method.

Hello putList,putListObject methods not found in the TinyDB class..

Older APIs was using the broken MULTI_PROCESS_MODE. Then people noticed it was unsafe.

Is this simplification reliable for multiple processes/services?

How does this compare in performance to tray and DPreference, for example?

I see there is some hack to plug/unplug the Gson: Uncomment the save objects methods in your copy of TinyDB.java, starting at: Line31, Line317, Line332, Line462, Line468

I may offer a solution where you can plug-in external components in a more elegant way.

The idea is to wrap external component into interfaces and the TinyDB.class may call it's methods. On application start you can deploy the optional component if necessary.

Here is an example of how it can be done: https://github.com/Scarabei/Scarabei/blob/master/scarabei-api/src/com/jfixby/scarabei/api/desktop/DesktopSetup.java

Would you be interested?

Hi there!
Why note making this class as a singleton or making it an option. I use it on my production app but I have modified it to be as a Singelton, so those who use shared preferences across their app, only initialize it once (when they use the TinyDB class for the first time). I can help to contribute to making these changes if the maintainer would approve.

I am using the phenomenal class! I can add, remove everything right!
But I need to list all the "Key" I used in tinydb.putListObject ("KEY", img);

Is it possible to do that?

Here is the error:

Using this method to save an object of a class wrapping a HashMap object is resulting in a LinkTreeMap Class casting error.
Eg Class:

public class Categories {
    private String categoryName;
    private ActivityMasterModel amm;

    @SerializedName("activities")
    @Expose
    private ArrayList<ActivityMasterModel> allActivities;

    private HashMap<String, ArrayList<ActivityMasterModel>> allActivitiesByCategory;

    public ArrayList<ActivityMasterModel> getAllActivities() {
        return allActivities;
    }

    public void setAllActivities(ArrayList<ActivityMasterModel> allActivities) {
        this.allActivities = allActivities;
    }

I couldnt save allActivitiesByCategory object into shared preferences using putObject method. Hence I created the above class to be used with putObject method. However, the object allActivitiesByCategory is saved using the below modified method.

public void putHashMapObject(String key, Object obj) {
       checkForNullKey(key);
       Type type = new TypeToken<Map<String, ArrayList<ActivityMasterModel>>>() {}.getType();
       Gson gson = new Gson();
       putString(key, gson.toJson(obj, type));
   }

I was following the below link and it helped a lot.
https://stackoverflow.com/questions/32444863/google-gson-linkedtreemap-class-cast-to-myclass

However, the same solution didnt work for SparseArray instead of HashMap. I couldnt solve the issue yet. I am not a Java guy, I should say a beginner, and trying to get my head around it.

Is there any way to modify the tinyDB class to be able to save a custom object with a DateTime field? I tried adding the following:
`
private class DateTimeSerializer implements JsonSerializer {
public JsonElement serialize(DateTime src, Type typeOfSrc, JsonSerializationContext context) {
return new JsonPrimitive(src.toString());
}
}

private class DateTimeDeserializer implements JsonDeserializer<DateTime> {
    public DateTime deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
            throws JsonParseException {
        return new DateTime(json.getAsJsonPrimitive().getAsString());
    }
}

public void retrieveGlobalDataFromStorage(Context context) {

// ...

    final GsonBuilder builder = new GsonBuilder();
    builder.registerTypeAdapter(DateTime.class, new DateTimeSerializer());
    builder.registerTypeAdapter(DateTime.class, new DateTimeDeserializer());

    final Gson gson = builder.create();

// ...
}` but I am still getting a fatal exception

Hi , My api interface class like this

public interface ApiInterface {
    @FormUrlEncoded
    @Headers("wkey",***********TinyDB*********)
    @POST("srrvk")
    Call<JoinAllAllowedInnoResponse> GETJOINALLOWEDINNOLIST(@Field("a") Integer lastOrderId, @Field("b") Integer rowCount);

I saved a wkey parameter in tinyDB, My question is how can I use tinyDB in my apiInterface class ?

Does this provide persistence to app closure and possible background kills? How does it perform in comparison to other storage methods? Perhaps you can say a few words in the README how to put this to use. We're looking for better and more efficient and simple methods for storing network/app information in our app, without SQLite overhead. Would this be suitable? Thanks.

Writing to this path requires the WRITE_EXTERNAL_STORAGE permission.

Starting in KITKAT, if your application only needs to store internal data, consider using getExternalFilesDir(String), getExternalCacheDir(), or getExternalMediaDirs(), which require no permissions to read or write.

http://developer.android.com/intl/es/reference/android/os/Environment.html#getExternalStorageDirectory()

Sorry, stupid question, fixed, please delete

when i store an image and i want to replace it i do the same code for putting it in with the same path name so it replaces it but it gives me errors. (TinyDb.checkForNullValue). Please is there another way to do it. That is to replace the image that has been stored in that path with another image

I have been trying to retrieve ListObjects but all to no avail. The issue here is the mClass. How do I go about it? Thanks. Nice work anyways

hi thanks for your useful class .
how can i find out if tinydb with key a is null or not .
example : if (tinydb.getint("a") == null);

I have a custom Object NotificationItem and an ArrayList of these objects. When I try to save the ArrayList using tinydb.putListObject I get this error:
Wrong 2nd argument type Found 'java.uti.ArrayList<dtcj.myapp.NotificationItem>', required 'java.util.ArrayList<java.lang.object>'
Can you please advise me how to correct this? Thanks, Taryn
Here is the relevant code
ArrayList<NotificationItem> notificationData = new ArrayList();`

NotificationItem medicineExample = new NotificationItem();

tinydb.putObject("medicineExample",medicineExample);

notificationData.add(medicineExample);

tinydb.putListObject("notificationData",notificationData);

For ,

ArrayList<Person> usersWhoWon = new ArrayList<Person>(); tinydb.putListObject("allWinners", usersWhoWon);

I got cannot resolve for tinydb.putListObject("allWinners", usersWhoWon); line usersWhoWon.
Error:
Wrong 2nd argument type. Found: 'java.util.ArrayList<electronic.business.card.data.model.EcardSavedContactData>', required: 'java.util.ArrayList<java.lang.Object>'

TinyDB tinydb = new TinyDB(context);

change to singleton getInstance();

I seem to be unable to find the license in any files within the TinyDB repo.

Hi, i was thinking that why you haven't implemented singleton pattern for this utility class, so that we can load this class just one time in whole application.
is there any special reason?
(i know that built-in shared preferences object uses singleton pattern by default)

First of all thanks for this class. But it would be great to have value change listeners. Is it discarded for the simplicity ?

Why some function receive as parameter a default value, for example, getLong and getDouble , but other functions like getFloat and getInt does not? It wouldn't be easier if all function received a default parameter that is return in case of error?

Issue with apply() when using GB(lvl 10), even when the doc states that this was added in API Level 9.
Used an old phone to test my app (min sdk 8) and it crashed, it was ok on phone(18) and Emulator(19).
Replacing with commit() solves the problem. Any true problem of apply() being replaced?

Can you guys please provide this class in kotlin?

Hi,

I'm loving your library so firstly thank you very much.

I am trying to check only grab an array list of strings from shared preferences only if they are null under a key. How can I do this?

Can you change list methods? Change ArrayList by Collection or Iterable interface.
Good work
