com.parse.ParseObject 不能转换为

Question

I am developing application which having Parse Platform . To fetch data I am calling ParseCloud.callFunctionInBackground function.

I have registered the Parse and its sub class into the Application class like below :

public class App extends Application {
    @Override
    public void onCreate(){
        super.onCreate();
        Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);    
        OkHttpClient.Builder builder = new OkHttpClient.Builder();
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
        httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        builder.networkInterceptors().add(httpLoggingInterceptor);    
        ParseObject.registerSubclass(ParseMessage.class);
        Parse.initialize(new Parse.Configuration.Builder(this)
                        .applicationId("KEY")
                        .server("URL")
                        .build());
    }
}

I have below model class which extends ParseObject :

@ParseClassName("ParseMessage")
public class ParseMessage extends ParseObject {

    // Ensure that your subclass has a public default constructor
    public ParseMessage() {
        super();
    }

    public ParsePhoto getPhotos() {
        return (ParsePhoto) getParseObject("photos");
    }

    public void setPhotos(ParsePhoto value) {
        put("photos", value);
    }

    public String getCaption() {
        return getString("caption");
    }

    public void setCaption(String value) {
        put("caption", value);
    }

}

When I calling this below method from my Fragment :

HashMap<String, Object> params = new HashMap<String, Object>();
ParseCloud.callFunctionInBackground("MY_METHOD", params, new FunctionCallback<ArrayList<ParseMessage>>() {
            public void done(ArrayList<ParseMessage> mapObject, ParseException e) {
                if (e == null) {
                    ParseMessage object = mapObject.get(i);
                    }
                } else {
                }
    }
});

But I am getting below exception :

java.lang.ClassCastException: com.parse.ParseObject cannot be cast to com.example.ParseMessage

I already searched lots of thins from Google and Stackoverflow, but I did not get any solutions of it. Can anyone help me into this as I already spend a lot of time on this. Below response which I am getting from Parse :

The info you have provided is not very concrete, but from the debugger screen, it looks like you are trying to convert ParsePhoto into ParseMessage . ParsePhoto is subclass of ParseObject , and I believe this is causing the issue.
