added the new permissions events and method for the SDK 26 release
In the example projecxt downloading a file and storing it on the internal sdcard of the device requires the permission android.permission.WRITE_EXTERNAL_STORAGE. In case the user does not grant that permission, the app will close.
This example shows how to download a file from a password protected area to your device. I prepared this webpage
http://restricted.puravidaapps.com using basic HTTP authentication, which means,
you can access this area only after login with username and password. Try it with username=appinventor and password=appinventor.
To be able to do the authentication with App Inventor, we have to add an Authentication header.
The Authorization header is constructed as follows (source: Wikipedia):
To make it as simple as possible, I just Base64 encoded the username:password string appinventor:appinventor using
this page which results in YXBwaW52ZW50b3I6YXBwaW52ZW50b3I=
and put that hardcoded into the header. That's all.
Developing and maintaining snippets, tutorials and extensions for App Inventor takes a lot of time.
I hope it saved some of your time. If yes, then you might consider to donate a small amount!
