You are writing message.text into the database inside the photo function. However, that function is only triggered for messages containing a photo. When the message contains a photo, message.text is None. Any caption the photo might have will be in message.caption.

The little lighter colored "ct" prompt is just a visual aid and it does not always show up. When you provide a raw value as an argument, it will show the prompt (like this, 1, or "foo"). When you provide a variable for the argument like ctx, foo, etc, it does not show up. This goes for all functions that take arguments.

The moral of the story is, it is not important and can be ignored.

let returns the result of last expression inside it, in this case the value of builder.create(), a non-nullable AlertDialog.

Since you use ?.let, if activity is null, let won't be called, and you will effectively have null ?: throw....

builder.create() never returns null, so this throw expression is only reached when activity is null, so the error message doesn't make sense.

This works fine with proper spacing:

The version 202.7660.26.42.7322048 is

On Windows, the software that runs the Android Emulator is called "qemu-system-x86_64.exe".

Try to kill this software. You can use the built-in taskkill utility from within the Command Prompt:

1. Open the Command Prompt (Type in CMD into the Windows search)
2. Enter: taskkill /F /IM "qemu-system-x86_64.exe" /T

Explanation of the taskkill command:

Apparently all you have to do is to close out the file. It seems to only show when the file is opened.

Perhaps a later version of Visual Studio can make this warning behave more consistently with a standard warning in VS. Really it behaves very much like a refactoring / code cleanup suggestion (which commonly has a grey, squiggly line), rather than an actual warning. It's like it's just been mislabeled in development or whatever. However the good thing is that as long as the file is closed, it doesn't pollute the build or the errors window with warning messages.

use Intellij CE the latest version released on April 6th has native support for m1 and its very fast and intuitive, i've been using it and it's not very different from android studio

You need to replace \ with \\ if you are giving path with jenkins in Windows.
May be if file path is too huge or that is the root cause you can try mounting the directory to a short path

EDIT : Based on your modified question :
Open Jenkins dashboard. Navigate to Manage Jenkins-> Configure System. Under the Global properties section add another environment variable named GRADLE_USER_HOME as shown below.
