I have a complex JSON which I need to parse and store the information that are inside the JSON data into Room database. Is it possible to store the whole JSON in Room? If that is possible I am up for that too. I am using Kotlin. Can anyone guide me to it?
Here's my JSON sample:
{
"chapters": [
{
"play": "manual",
"items": [
{
"image": "/path/to/image",
"background": "#ffffff",
"text": "text to show on image",
"points": 1,
"voice": {
"type": "tts"
},
"words": {
"type": "wav",
"file": "/path to words file",
"parts": [
{
"word": "text",
"from": 122,
"to": 116
}
]
}
},
{
"image": "/path/to/image",
"background": "#ffffff",
"text": "text to show on image",
"points": 1,
"voice": {
"type": "wav",
"file": "/path/to/file"
}
}
]
}
]
}

I am a newbie to android. I am stuck at JSON parsing.
Following is my JSON, in this, the type of menu categories will be dynamic, and I want to arrange this JSON in sectioned recycler view.
Please help me out.
This is my JSON
{
"menu_items": {
"Plat": [{
"menu_name": "jambon à l'os",
"menu_cost": "18.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
},
{
"menu_name": "tacos",
"menu_cost": "6.00",
"menu_count": "1",
"category": "Plat",
"menu_tax": "5.50",
"code": "€"
}
],
"Entrée": [{
"menu_name": "avocat",
"menu_cost": "7.50",
"menu_count": "1",
"category": "Entrée",
"menu_tax": "5.50",
"code": "€"
}]
},

Check this out. Create a generic response class. Extend your classes from that class. To do this properly you can look at Java Generics and Inheritance topics if you are using Java. And then search about Sectioned RecyclerView in Android. Here is a library for this.
Here's the JSON where jsonObject key is dynamic :
{
"CH000032": [
{
"type": "event",
"details": {
"programID": "MV10000032",
"programType": "MOVIE",
"title": "Titanic",
"year": "1997",
"rating": "PG-13",
"durationSec": 11640,
"startTimeSec": "",
"endTimeSec": "",
"language": "ENG",
"isHD": true,
"Genres": [
"Movies",
"Action"
],
"description": "A seventeen-year-old aristocrat falls in love with a kind but poor artist aboard the luxurious, ill-fated R.M.S. Titanic.",
"imageUrl": "http://res.cloudinary.com/dte07foms/image/upload/c_scale,h_405,w_270/l_Copyright_e3jt1k/v1508831090/Titanic_b0hqo0.jpg"
}
}
],
"CH000033": [
{
"type": "event",
"details": {
"programID": "EP10000132",
"programType": "EPISODE",
"title": "A Chic Bar in Ibiza",
"seriesTitle": "Two and a Half Men",
"seasonNumber": 12,
"epsiodeNumber": 2,
"year": "2014",
"rating": "TV-14",
"durationSec": 1260,
"startTimeSec": "",
"endTimeSec": "",
"language": "ENG",
"isHD": true,
"Genres": [
"Comedy",
"Romance"
],
"description": "Alan has second thoughts about getting married when Walden has him sign a prenup.",
"imageUrl": "http://res.cloudinary.com/dte07foms/image/upload/c_crop,h_405,w_270//l_Copyright_e3jt1k/v1508831090/2AndHalfmen_splkro.jpg"
}
}
]
}
I would like to parse this JSON. Please let me know how should the class
be written with #SerializedName annotation using Retrofit.
Note : CH000032, CH000033 etc are dynamic.
You can use Map<String, ModelClassName> in your model class for dynamic like below :-
public class Data {
#SerializedName("your_key")
#Expose
private Map<String, ModelClassName> result;
//....
}
this can help to parse dynamic key in retrofit.
What you are asking will take much work , instead a better approach will be to change the structure o json to something like this -
"data": [
{
"type": "event",
"programID": "MV10000032",
"programType": "MOVIE",
"title": "Titanic",
"year": "1997",
"rating": "PG-13",
"durationSec": 11640,
"startTimeSec": "",
"endTimeSec": "",
"language": "ENG",
"isHD": true,
"Genres": [
"Movies",
"Action"
],
"description": "A seventeen-year-old aristocrat falls in love with a kind but poor artist aboard the luxurious, ill-fated R.M.S. Titanic.",

},
{
"type": "event",
"programID": "MV10000032",
"programType": "MOVIE",
"title": "Titanic",
"year": "1997",
"rating": "PG-13",

"startTimeSec": "",
"endTimeSec": "",
"language": "ENG",

],

}]
I'm having this response JSON that theorically follows the JSON API specs. I'm trying to parse with the moshi-jsonapi library but I don't know how to parse the some_objects relationship. In the SomeType class I have a member HasMany<SomeObject> someObjects and the class SomeObject is annotated in a proper way:
#JsonApi(type = "some_objects")
public class SomeObject extends Resource {
//....
}
But, after doing the parsing, I'm getting the someObjects member as null. Anyone knows why?
The JSON is that one:
"links": {
"self": "someurl/params"
},
"data": [
{
"type": "some_type",
"id": "12345",
"attributes": {
"attr1": 1,
"attr2": 2,
"attr3": 3
},
"relationships": {
"some_objects": {
"data": [
{
"type": "some_objects",
"id": "1"
},
{
"type": "some_objects",
"id": "2"
}
]
}
}
}
],
"included": [
{
"type": "some_objects",
"id": "1",
"attributes": {
"id": "1",
"parentId": "1"
},
"relationships": {
"subobjects": {
"data": [
{
"type": "subobjects",
"id": "2"
}
]
}
}
{
"type": "subobjects",
"id": "2",
"attributes": {
"metadata": {
"code": "AA"
},
"id": "2",
"parentId": "1"
}
}
],
"meta": {
"total": 1,
"totalCount": 1,
"correction": []
}
}
The only problem was the name of the member, after changing someObjects by 'some_objects' it worked like a charm.

when I parsing this json object, String key "likes" is sometimes exist and sometimes do not exist in "data" jsonArray. So when I parsing JsonString "likes", sometimes I gets JSONException since I am parsing null value. Is there any way to skipping "null" json value?
Please help me regarding this.
if try catch it, next processes will be skipped.
you can check by isNull("name") method.
Edit: this is to check key. since you mentioned key exists sometimes. did you mean the value?
use JSONObjects method has(key)
data = (JSONObject) new JSONTokener(jsonObjRecv.toString()).nextValue();
if data.has("like"){
...
}
to check whether the value is null check with isNull("name")
I have a problem getting my feeds.
1- I (emiliano nunez) post a photo with my cellphone (android) and add (With) "hall 9000".
I (hall 9000) get feeds by graph api:
https://graph.facebook.com/me/feed?access_token=..........
{
"from": {
