'Attempt to use invalid handle -1' error - Etchot - 2018-02-04

I am learning Python through the development of a Kodi add-on. I am trying to display an image using the xbmcplugin.setResolvedUrl() function but I get an error:

Quote:'Attempt to use invalid handle -1' error.

I am getting rid of the error when including li.setProperty("IsPlayable", "true") in my addFile function but then the image is not displayed. What am I doing wrong?

Code:
import sys

import urllib

import urlparse

import xbmcgui

import xbmcplugin

import xbmcaddon

my_addon = xbmcaddon.Addon()

addon_path = xbmc.translatePath(my_addon.getAddonInfo('path'))

base_url = sys.argv[0]

addon_handle = int(sys.argv[1])

args = urlparse.parse_qs(sys.argv[2][1:])

mode = args.get('mode', None)

def build_url(query):

    return base_url + '?' + urllib.urlencode(query)

def addFile(filename, filepath):

    filedir = build_url({'mode': 'display', 'filepath': filepath})

    li = xbmcgui.ListItem(filename)

    xbmcplugin.addDirectoryItem(handle=addon_handle, url=filedir, listitem=li)

def displayImage(url):

    li = xbmcgui.ListItem('Sample image')

    li.setPath(url)

    xbmcplugin.setResolvedUrl(addon_handle, True, listitem=li)

if mode is None:

    fileurl = 'https://elmicrolector.files.wordpress.com/2016/10/breu-14-a1.jpg'

    addFile('Sample image', fileurl)

    xbmcplugin.setContent(addon_handle, 'files')

    xbmcplugin.endOfDirectory(addon_handle)

elif mode[0] == 'display':

    displayImage(args['filepath'][0])

you have to include li.setProperty('IsPlayable','true') in addFile. if not you are not actually getting a resolveUrl playback.

When I include li.setProperty("IsPlayable", "true") in my addFile function the error is not shown but then the image is not displayed. It looks like I am notgetting a resolveUrl playback.

did you mark the listitem as a file ?

Sorry, what do you mean?

My quick experiments showed that setResolvedUrl plugin path does not work for photos, like it does for videos, unless I'm missing some non-obvious option. For photos only direct URLs are working.

You are absolutely right! When I replace the url of the photo with a url of a video and I include li.setProperty("IsPlayable", "true") in my addFile function, the xbmcplugin.setResolvedUrl() function works fine.
