I made this question two days ago, and ianhanniballake replied me with the right solution. Now, I am trying to follow this example.
Now, it's not loading the image.
I changed the line:
Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.pano1);
for the line:
Uri.parse("http://s24.postimg.org/d81cxh2sl/pano1.jpg".toString());
What can it be?
Looking at the Android SDK you cannot use a http resource for that URI:
the URI of the panorama to load info about. May be a file:, content:, or android_resource: scheme.
So you need to download the image first before you can process it. Check this link for a tutorial on this.
