问题 I am getting following exception in different areas of my project. And worst thing is I have no idea what it is... I do not have com.b.a.c.b package in my project. I tried searching on web but still, I am not understanding what is causing this exception. This exception is thrown on onCreate() method (I guess) after an Intent call from another Activity . Note: I am using gson 2.2.4 with POJO method, just before this I got this exception, I was facing error in JSON creation with same kind of

GSON identifying JSON Object as Primitive

独自空忆成欢 提交于 2019-12-25 02:39:15
问题 I am writing a relatively simple messaging app that saves its logs in the JSON format, and I am using the GSON library to parse these. I load a JSON file from a server, and put it trough Gson.toJsonTree() function. I'm not sure this is expected, but when I test the result from the previous function with the isJsonSomething() functions ( isJsonObject , isJsonAray , isJsonNull , isJsonPrimitive ), isJsonPrimitive returns true, and I can't parse it into a object. This is my JSON file's contents:

Deserializing 2D JSON array to bean using GSON

两盒软妹~` 提交于 2019-12-25 02:19:14
问题 I have not been able to map this nested array rows->elements to my javabean. Is gson actually capable of handling this kind of mapping? I also tried a different approach, which you can see if you look at the commented out Java code. package scratch; import java.util.ArrayList; import java.util.List; /* { "rows" : [ { "elements" : [ { "distance" : { "text" : "897 mi", "value" : 1443464 }, "duration" : { "text" : "14 hours 32 mins", "value" : 52327 }, "status" : "OK" } ] }, { "elements" : [ {

How to handle a Boolean when expecting a String in GSON? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I am currently developing with a 3rd party REST API. I am creating objects for their JSON objects being returned by the API. I am following their documentation where it says certain variables will be Strings. Sometimes when there is no String, it will return False. Sometimes I'm expecting a URL and I get False.

How to change resulting Json when serializing, more or less globally, if class declarations can not be changed?

…衆ロ難τιáo~ 提交于 2019-12-24 20:52:15
问题 Assume that: there is a bunch of Java objects that you need to pass - for example - to some API you are not willing or can not change declaration for those objects unfortunately API requires something that is not declared in those objects As an example (inspired by this question) there is a simple class: @Getter @RequiredArgsConstructor public class Login { private final String username, password; } However, API expects JSON like: { "username": "uname", "password": "pword", "version": 1 } and
