Oh, great. There's always something else that some... Grrr...
Anyway, so I worked days and days wading through vague, incomplete, and contradictory Picasa information so that my Android app could find a Picasa picture and download it using the download manager. So just now I made the finishing touches and hit the "run" button. Everything went fine until DownloadManager tried to download the file:
java.lang.IllegalArgumentException: Can only download HTTP URIs: https://example.com/image.jpg
Tell me you're joking. Tell me they didn't make a download manager that can't handle SSL...
Better yet, tell me how to turn on SSL access in the Android download manager.
I had the same problem previously. Yup I see HTTPS support is already in ICS, but not in 2.3.7 and below, but we can extract the source code to create a DownloadManager to support that.
Based on the sample code from http://android-er.blogspot.com/2011/07/sample-code-using-androidappdownloadman.html i made a demo with extracted DownloadManager to support HTTPS.
You can find the sample code here https://github.com/alvinsj/android-https-downloadmanager-demo, run by just changing the url to your https based url.
