Prefs | Simple Android SharedPreferences wrapper | Android library

I need a Singleton for the shared preferences which has async initialisation but also works with null safety. Usually I used the following singleton implementation, but what is the best way to have a singleton which works with null safety?

This code is responsible for switching from a light theme to a dark one. The last line of code is responsible for the options for switching from dark to light theme: a white button and a sliding yellow color.

Tell me how can I achieve that on a light background this button is black and slides with yellow accompaniment.

I will also be grateful if you tell me how to make the width of this button the same as the top two.

I'm stuck. My notification in the background show twice. But in the foreground only one notification. This is my code

I'm desperately trying to have as default a 3 columns layout in RStudio and can't manage to obtain it.

I tried to find some documentation, but found nothing with some details or explanation on the "panes" parameters of the rstudio-prefs.json file.

In "C:\Users...\AppData\Roaming\RStudio\rstudio-prefs.json", I saw that it is possible to add a source column using "additional_source_columns": 1 but it is automatically set back to 0 every time I restart R and the problem is that it creates an untitled script in addition to the one I'm opening.

Here are the steps I have to perform to obtain the final layout I'm looking for.

Open a script by double clicking on it

Press CTRL + F7 to add a source column

Drag and drop my script to the left column

remove the 'untitled' script

Thank you for your help ! A link to any documentation that you may know of that I didn't find would be life-saving.

Fellows,

I'm doing some webscraping and need to download multiple PDFs from the www1.hkexnews.hk website.

However, I encountered a problem while trying to make my Selenium chromedriver tick the box that appears every time one wants to download a PDF on the said website. The code executes, but the box still appears unclicked.

Please refer to my source code below - would appreciate any advice!

I am trying to save push notification title and body using shared_preference and and trying to get that saved data in my card view or listtile meaning i wanna show the list of notifications inside my app which i saved locally using shared preference:

What im looking to achieve is pulling a csv file from a workorder app that we use. Then convert it using pandas and remove unnecessary columns. Then post this info into slack using a webhook. I dont have access to the slack API. So far this is what i came up with but am finding it hard to get the data into a format that i can send.
