Why Does GSON Throw 'Expected BEGIN_OBJECT but was BEGIN_ARRAY' When Parsing JSON Arrays?

Expected BEGIN_OBJECT but Was BEGIN_ARRAY with GSON

When attempting to parse a JSON string containing an array of objects into a list of objects using GSON, the issue of "Expected BEGIN_OBJECT but was BEGIN_ARRAY" arises. This occurs because GSON anticipates parsing a single object, but instead encounters an array of objects.

To resolve this, the correct method is to specify that the expected data structure is an array of objects. This can be achieved by modifying the code as follows:

ChannelSearchEnum[] enums = gson.fromJson(yourJson, ChannelSearchEnum[].class);

Alternatively, for greater flexibility, you can use the following code:

Type collectionType = new TypeToken<Collection<ChannelSearchEnum>>(){}.getType();
Collection<ChannelSearchEnum> enums = gson.fromJson(yourJson, collectionType);
