Description

Hey gentlemen, I am developing a cross-platform controller of an IOT device which it's GUI is done using kivy. It works fine on python 3.0+ on linux and windows. I just finished the android build on a fresh Ubuntu 18.04 vmware virtual machine with a windows host using kivy android packaging guide. Well the problem started from a kivy filechooser which seems like it cant access /storage/emulated/0 or any other symlinks to it(e.g. /mnt/sdcard). The android device which I'm testing my app on is a Samsung Galaxy Note 5 running Android 7.0 with no sdcard. The other problem that I have which im not sure about it yet, is that seems like my app cannot access network but I need to look more for that. The problem is that I have set INTERNET, READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE in my buildozer.spec file as the permissions but yet nothing changed. So as a summary my app seems to have these problems:

  1. Cannot access device storage. (Internal)
  2. Cannot access internet.

Though Both permissions are acquired in buildozer.spec. Thanks in advance.

#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Feels more like a support request than a bug right? Maybe try to ask on Discord. I do have both storage and internet working on my apps. It's not clear to me what's your error is. Also, people are willing to help, but are just too busy with other things, so making their lives easier would max your chances of getting helped. Which means minimal reproducing example and straightforward description. For example you should narrow your issue down as much as possible to reduce all possible noise. Side effect of that is you may be finding/fixing the issue yourself. See you on Discord support channels :+1:
