Without stacktrace,
Let me guess,
You used some static variables and their values lost, so you got a NullPointerException. And when it occured device wasn't at debug environment for getting stacktrace :)

I have two computers, both with same hardware and Android Studio settings.
When I build the app on the first, the app works well, but when I build the app on the second, some parts of the app lifecycle just don't work.
Example: the app never pass through the onCreate()

how can I create a simple app that retrieve any data from server, I am stuck I don't know how I can start if anyone can help me?
You can use ktor, which is a networking library from Jetbrains. See an example here:
https://github.com/touchlab/KaMPKit/blob/kpg/ktor_hack/shared/src/commonMain/kotlin/co/touchlab/kampkit/ktor/DogApiImpl.kt#L38
The request needs to be made on the main thread in native, just FYI.

I am trying to make a program that will use the time and display it down to the seconds. How do I do this?
So far I have found the function get_time() that is part of kivy but I am not sure how to use it. I have imported everything but it still says "not defined".
import datetime
datetime.datetime.now()
that should work on any python framework.
you can use the Documentation for more details.

I inherited some code where there are some Activity classes that are completely commented out. I'm having trouble figuring out where the activity code is actually happening and so I'm just wondering if /* at the beginning of a class might have some special significance to Android that I don't know about
No, it has no special meaning. The code is somewhere and it's not commented out.

Can anyone tell me where to search for the following?
I'm trying to create an application that allows the user to schedule an SMS to be sent at a specific time.
I can do this when the application is open and running but I want my application to work even if it is not running, using a service for example.
Can anyone tell my where can I find any resource for doing that?
U will need to use WakefulBroadcastReceiver to achieve this see this example
