Why Does GSON Throw 'Expected BEGIN_OBJECT but was BEGIN_ARRAY' and How Can I Fix It?

GSON Exception: "Expected BEGIN_OBJECT but was BEGIN_ARRAY"

Error Message:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2

Problem Overview:

Your JSON response is an array of objects, but you're attempting to parse it as a single object.

Solution:

To resolve this issue, you need to adjust your code to properly handle the array structure. Instead of trying to parse the JSON string as ChannelSearchEnum.class, you should parse it as an array of ChannelSearchEnum objects.

Corrected Code:

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

This revised code will correctly parse the JSON string as a collection of ChannelSearchEnum objects, resolving the "Expected BEGIN_OBJECT but was BEGIN_ARRAY" exception.
