The entire JSON gets parsed and gets converted to its corresponding model object using GSON.
For some reasons, if the JSONArray "video" is empty, the GSON throws an exception.
While parsing the JSONArray "video" if the array is empty-([]) then parsing will throws exception
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 445 path $.video.
If the "video" is an empty JsonArray, what I need is the model object pointing to that jsonarray needs to be null.
Model Object For Video:
public class Video {
@SerializedName("date")
@Expose
private String date;
@SerializedName("video_list")
@Expose
private List<VideoList> videoList = null;
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public List<VideoList> getVideoList() {
return videoList;
}
public void setVideoList(List<VideoList> videoList) {
this.videoList = videoList;
}
public static List<CustomVideoList> getCustomizedVideoList(List<Video> videos) {
List<CustomVideoList> customVideoList = new ArrayList<>();
if (videos != null && videos.size() > 0) {
for (Video video : videos) {
String headerDate = "";
CustomVideoList customVideoHeader = new CustomVideoList();
customVideoHeader.setHeader(true);
headerDate = video.getDate();
customVideoHeader.setHeaderDate(headerDate);
customVideoList.add(customVideoHeader);
for (VideoList videoList : video.getVideoList()) {
CustomVideoList customVideo = new CustomVideoList();
customVideo.setId(videoList.getId());
customVideo.setScvName(videoList.getScvName());
customVideo.setScvDescription(videoList.getScvDescription());
customVideo.setScvComments(videoList.getScvComments());
customVideo.setScvStatus(videoList.getScvStatus());
customVideo.setScvType(videoList.getScvType());
customVideo.setScvUrl(videoList.getScvUrl());
customVideo.setIdPlayer(videoList.getIdPlayer());
customVideo.setScvCreatedby(videoList.getScvCreatedby());
customVideo.setScvCreated(videoList.getScvCreated());
customVideo.setScvModifiedby(videoList.getScvModifiedby());
customVideo.setScvModified(videoList.getScvModified());
customVideo.setScvThumb(videoList.getScvThumb());
customVideo.setHeaderDate(headerDate);
customVideoList.add(customVideo);
}
}
}
return customVideoList;
}
}
The Json what cause exception since "video" is empty JSONArray:
