In my desperation with trying to get LiveFolders working, I have tried the following in my LiveFolder ContentProvider:

public Cursor query(Uri uri, String[] projection, String selection,
        String[] selectionArgs, String sortOrder) {
    MatrixCursor mc = new MatrixCursor(new String[] { LiveFolders._ID, LiveFolders.NAME, LiveFolders.INTENT } );
    Intent i = null;

    for (int j=0; j < 5; j++) {
        i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com/"));
        mc.addRow(new Object[] { j, "hello", i} );
    }

    return mc;
}

Which, in all normalness, should launch the Browser and display the Google homepage when clicking on an item in the LiveFolder. But it doesn't. It gives a Application is not installed on your phone error. No, I'm not defining a base intent for my LiveFolder.

logcat says:

I/ActivityManager(   74): Starting activity: Intent { act=android.intent.action.VIEW dat=Intent { act=android.intent.action.VIEW dat=http://www.google.com/ } flg=0x10000000 }

It seems it embeds the Intent I give it in the data section of the actually fired Intent. Why is it doing this? I'm really starting to believe it's a platform bug.
