How To Transfer Escaped Json Lines To List Of Beans
Java POJO: import android.os.Parcel; import android.os.Parcelable; import com.gongzelong.duolingowordsearch.utils.ParcelableUtils; import com.google.gson.annotations.SerializedNa
Solution 1:
Your "JSON" does not look like a JSON. More like list of escaped JSON objects. To deserialise it properly you need to unescape JSON and remove " chars at the beginning and at the end. Also, word_locations / translations is not a list - it is a Map. Let's assume that your payload looks like this:
