And finally, this is the code I use to read the JSON and store as JSON objects,
SharedPreferences Tempx = getSharedPreferences("ActivitySession", Context.MODE_PRIVATE);
SharedPreferences.Editor edx = Tempx.edit();
edx.putString("GSON_FEED", response.toString());
edx.apply();
Gson gson = new Gson();
JsonParser parser = new JsonParser();
try{
JsonArray jArray = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonArray();
for(JsonElement obj : jArray )
{
MainPojo cse = gson.fromJson( obj , MainPojo.class);
TweetList.add(cse);
}
}catch(Throwable e) {
JsonElement obj = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonObject();
MainPojo cse = gson.fromJson( obj , MainPojo.class);
TweetList.add(cse);
}
Though I am able to log the JSON as String, I don't know if I am storing it the wrong way, any help will be much appreciated, Thanks!
You could define a custom deserializer and register a type adapter with GSON. Also
why are you using this:
JsonArray jArray = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonArray();
.. when you intend to use GSON for deserialization? You could just do it in your deserializer.
https://sites.google.com/site/gson/gson-user-guide#TOC-Custom-Serialization-and-Deserialization
EG:
public class FooDeserializer implements JsonDeserializer<Foos>
{
#Override public Foos deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException
{
JsonObject jsonObject = json.getAsJsonObject();
JsonArray statusArray = jsonObject.get("statuses").getAsJsonArray();
Foos result = new Foos();
ArrayList fooArray = new ArrayList<>;
for (JsonElement e : statusArray) {
fooArray.add(new Foo());
}
result.setFoos(fooArray);
return result;
}
}

I created morphia and told it how to map:
morphia = new Morphia();
morphia.map(AbbyyParameters.class,
CustomProfile.class,
ProfileProperties.class,
ProfileProperty.class);
After storing the class in the database the document look like this:
{
"_id" : ObjectId("5b2906a0cac45b8d42bbda91"),
"wordListEncoding" : "ISO-8859-15",
"description" : "",
"name" : "1",
"predefinedProfile" : {
"type" : "DEFAULT"
},
"customProfile" : {
"properties" : {
"PageAnalysisParams" : {
"properties" : [
{
"name" : "DetectBarcodes",
"value" : "true"
}
]
},
"RecognizerParams" : {
"properties" : [
{
"name" : "TextLanguage",
"value" : "English,German,Digits,French,Italian,Spanish,Croatian,Slovak,Bulgarian"
}
]
}
}
},
"treatBarcodeAsWord" : false,
"documentExportEnabled" : false,
"creationDate" : ISODate("2018-06-19T13:35:26.019Z"),
"changedDate" : ISODate("2018-06-19T13:35:28.441Z")
}
When I try to retrieve the document I get the following error:
Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType
at org.mongodb.morphia.mapping.EmbeddedMapper.readMap(EmbeddedMapper.java:166)
I stepped into the code so I found that this code raises the exception:
new EphemeralMappedField((ParameterizedType) mf.getSubType(), mf, mapper);
mf.getSubType() returns ProfileProperties so I guess I have misconfigured something there?
What do I have to do that I can retrieve my document?
I'm struggling to implement a solution to retrieve multiple values from my api response ( https://www.thecocktaildb.com/api/json/v1/1/lookup.php?i=13060 ) and assign specific values to an array. Specifically values, strIngredient1, strIngredient2, strIngredient3 etc...

I know enough to realise that a large number of variables, ingredients and measures (many of which are empty) is the wrong approach but i'm struggling to find a solution with retrofit to create an array of these values. I've not found any way to assign multiple SerializedNames to a single array variable?
The option that jumps out at me is looping through the response pulling out the key values in onSuccess but this seems to go against the simplicity of using retrofit?
I am trying to load this test json string into an object using Gson but every element carries null. There is no exception triggered during the conversion. Please let me know what I might be doing wrong.
Appreciate your help.
I am writing a longer comment here only because it is throwing an error for not writing enough text to ask my query. I can't imagine why it would do such checks.
