            Android Widget with collection (ListView) not displaying items
            Asked 2021-Jan-19 at 13:18

            I am trying to do a simple widget for my app, which displays data from an API on the widget using ListView, but the list is empty even tho Logs says that the data was downloaded successfully. Blank listView is displayed with no data in it. No errors are shown. What's the cause of it?

            Resources I used when tried to solve this problem:

            official documentation - https://developer.android.com/guide/topics/appwidgets#collections

            similar question - How to use listview in a widget?

            my AppWidgetProvider

            ...

            ANSWER

            Answered 2021-Jan-19 at 13:18

            I found my mistake, turns out my API call shouldn't be asynchronous because as the documentation says:

            public void onDataSetChanged() -> You can do heaving lifting in here, synchronously. For example, if you need to process an image, fetch something from the network, etc., it is ok to do it here, synchronously. The widget will remain in its current state while work is being done here, so you don't need to worry about locking up the widget.

            So getting my data from Asynchronous call was the reason why data wasn't displayed

            Install SimpleCoin

            You can download it from GitHub.
            You can use SimpleCoin like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
