android image cache library
android cache images from url
glide image caching android
how to load images faster in android
glide android
picasso android
android-glide load multiple images
glide loads the old cache image instead of the new image

when i am using thsi api:

private static final String JSON_URL = "";

image is showing when internet is disconnetd so there is no need of caching required;

I am retrieving like this in try block

JSONObject obj = new JSONObject(response);    
JSONArray teamArray = obj.getJSONArray("heroes"); 

but when i am using this api:

private static final String JSON_URL = "   private static final String JSON_URL = "";

there is no json object so i am retrieving like this in try block and in this image is not loading when internet is disconnected:

JSONArray teamArray=new JSONArray(response);

so i wanna know is there any difference in api having json object and one having json array.Does Having json object caches your images automatically?

Below is my code,how to load images when internet is not there?
