Check Java ..

U will find Mahmoud_Magd___DownloadHelper class.

The class method "startDownload();" takes an ArrayList <HashMap<String, String>> which represents the items u want to download .. (U should create that list in the activity then pass it to class)

each item map contains the url and the path that it should be downloaded to .. (You should grant write permission)

During the each download .. it repeatedly calls the progressCallback with (HashMap<String, String> item, int progress)

After it each download finishes it call endDownloadCallback returning 2 ArrayList <HashMap<String, String>> ..

1) successfulDownloads .. contain a list of the successfully downloaded item maps (each with the url & path keys)

And

2) failedDownloads .. contain a list of the failed downloads item maps (each with the url, path & error keys)

Note .. you don't have to use the ArrayList <HashMap<String, String>> U can use the default ArrayList <HashMap<String, Object>> Provided by default in sketchware ..

I used ArrayList <HashMap<String, String>> Since the keys in string And the values are in string also .. So its just more accurate .. But u still can use the default lists if u hate the command blocks
