SmartMirror | Motion controlled SmartMirror

I apologize if the answer to this question is simple, but I'm just beginning to learn UWP and really can't figure out a solution on my own.

I have a UserControl called ClockWidget included in a Canvas in my main page. When running the application, the control (containing only a TextBlock) has the correct size, but the text does not seem to be rendered.

MainPage.xaml

First of all, sorry for that vague title. I am making a python application that shows time, fetches weather and News. Now, when i print news through tkinter label, it prints the titles of news on a separate line but in the center. If I try to specify the .pack(side=LEFT) geometry, it goes to the left but all the headlines print in a string and not in a newline. I have tried adding new line by '\n' and even carriage return '\n' but in vain. Please help me out with this issue. Attaching the code below.

P.s i could not get it the news to work with the For loop so i manually printed arrays.

When I open this activity in my app (Template1Activity) the app crashes with the following message:

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.SharedPreferences android.content.Context.getSharedPreferences(java.lang.String, int)' on a null object reference

My code for Template1Activity is:

I'm currently working on a Smartmirror project with a Raspberry Pi Zero W and I need my java program to check the internet connection so that I know wether I can update my weather data. For this method I use the iwgetid command to get the SSID. The problem is the following: I takethe return of the command line and put it into an if block. Even though the return(which I checked is the correct outprint) is correct the boolean returns false as an output.

I am building a Kivy application which will serve as a SmartMirror. The mirror is supposed to go into the main menu, which I already programmed, if a certain event fired, otherwise the screen should remain black. This means on that event I need to load all the body.kv file and after a certain timeout the body should be unloaded.

im currently trying to integrate design data in my UWP app. I've followed for this approach the steps from microsoft: https://docs.microsoft.com/en-us/windows/uwp/data-binding/displaying-data-in-the-designer

My problem: The data will not show up. Only the names of the bindings:

But I expect a result more like this: (Older version, screen from runtime)

So how I've implemented it?
I decided to use a "DesignInstance", because there is already a ViewModel which will be later used anyway (wich works currently fine at runtime).

Because of this, my "MockupViewModel" inherits from the original ViewModel and creates imaginary values in the default constructor:
