I want to download a file using the URL provided by me at a specific location in Android 12.
So, I used Android Studio to create the application to do this task. The app is simple. When the application is launched it will check if the directory is present or not. If the directory is not present then it will create the folder and download the image using provided URL at a specific folder (/storage/emulated/0/Download/demo) with the help of the download manager.
Below is the code sample:-
public int downloadUrl() {
String url = "https://www.whatsappimages.in/wp-content/uploads/2021/07/Top-HD-sad-quotes-for-whatsapp-status-in-hindi-Pics-Images-Download-Free.gif";/*editText.getText().toString();*/
File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/demo");
if (!direct.exists()) {
direct.mkdirs();
Log.d(TAG, "downloadUrl create folder demo: " + direct.getPath());
}
DownloadManager mgr = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle("Demo")
.setDescription("Something useful. No, really.")
.setDestinationInExternalPublicDir("/demo", "test.jpg");
mgr.enqueue(request);
return 0;
}
But not able to download.
Below are the logs:-

-------------------
You can see in the above logs that the folder is created but when the download is started the exception is coming.
So I want to create a public directory like Downloads, DCIM, etc in android using the framework.
Can someone please help me with this issue? Thanks in advance.
