guessit | python library that extracts as much information | Media library

Basically one function of my app should get an array with different strings from Firestore. Then another function should select 3 different strings from that array and store it in a list. The strings should not be identical, so in the end the list should have 3 unique random strings from the array I got from Firestore.

To achieve this I have the code below (which unfortunately I did not write by myself). Most of the times this code works fine, but sometimes I don't get any value. So as I said sometimes I get this error, which points me to the removeDuplicatesmethod:

I am trying to send two strings via a bundle to the next fragment but the app crashes even before I get to the first fragment.

I get this error in the second fragment:

I have a problem on my tensorflow js model, I followed a course (link to the course) where I learned to create a tensorflow model and everything worked fine but the course doesn't show how to use the model so I developped myself this part but every time I try to predict a number I got the same result (2), I don't know why and I don't have the knowledge to fix that so I hope someone could help me fix that and provide an explenation.

The guest part of the code is here :

I suddenly get this error and I don't know how to resolve this. I already tried all suggestions here Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve but nothing worked for me.

What I already tried:

• updated my sourceCompatibility and targetCompatibility from 1.7 to JavaVersion.VERSION_1_8 as it was suggested to me
• Deleted the .idea folder
• deleted google-services plugin, implementation 'com.google.android.gms:play-services-auth:17.0.0' in .gradle (app) and google services class path in .gradle (project) --> error still occurs
• When I update the google-services class path in the project file to the newest version 4.3.2 I get this error
• deleted the google-services.json and downloaded a new one

When an email verified user logs in for the first time in my app everything works as expected (he gets to a welcome screen and then to the MainActivity) but when he logs out out and logs in again there is a null pointer exception. When a user logs in for the second time he should go straight to the MainActivity and not to the welcome screen which you see in the below code.

This was a known issue about a year ago so my question is how to resolve this issue? Has this bug been fixed and when yes what did I do wrong in my code?

The question I am referring is here :Firebase user returns null metadata for already signed up users

Here is the code I am using to check whether the user logs in for the first or second time:

so I am new to Python and what is a good way to learn it is to do some personal project :) So I am on my Windows and using virtualenv to contain environment
