We could grab the Object with key “accountIcons,” cast it to a List>, and then iterate over and parse the items as desired. If we wanted to manually parse the data, we could change the type of subjectsJsonNode to be a Map. AssetBundleBuilder: Provides helper methods for building AssetBundles with various texture compression formats. AndroidBuildHelper: Provides helper methods for accessing or persisting build-related settings. Note that for the setSubjects method we specify the argument as a JsonNode since the readValue() method requires a JsonNode. Classes AndroidAppBundle: Provides utilities related to Android App Bundle. class ) // this helper method can be used to make JSON parsing a one-line operation public static T parseJson ( JsonNode node, Class class ) parseJson ( newsFeedItemJsonNode, NewsFeedItem. newsFeedItemJsonNode is a JsonNode containing the JSON to be parsed // the second parameter specifies the class of the object you want back JsonUtils. Jackson best practices recommends one re-use object mappers since creation of the mapper is an expensive operation - so our JSON helper class has a defaultMapper() method. This method throws some exceptions so it’s recommended you create a helper method that catches these exceptions instead of having try-catches everywhere you are parsing (our JSON helpers are in a class called JsonUtils). To parse JSON, you can use Jackson’s treeToValue method. If you’re using Jackson 2.0, please see my post on upgrading from Jackson 1.9 to 2.0. Update: This post applies to Jackson 1.9.
