            I tried to validate the XML against the XSD.

            The validation revealed few errors.

            You need to make a decision about what is correct XML or XSD.

            Refactoring repetitive if statements from API call
            Asked 2021-Feb-02 at 00:18

            I have used four very similar if statements in order to choose which weather icon to display for my weather app project.

            I have tried using for loops, forEach, googling, experimenting but I can't quite seem to refactor it and keep the functionality.

            I have taken the first four items of an array for weather forecasts from OpenWeatherMap, and depending on the weather code of a specific array (which represents a time), I display the respective icon.

            I have the functionality but I have a lot of repeated code, will someone please help me refactor this or point me in the right direction? This is my first proper project so please be gentle! Thank you for any help in advance :)

            CurrentUser only exists in the Firebase Android SDK. You cannot use both Android SDK and Admin SDK together. They have conflicting packages/classes. Specifically, you cannot use the Admin SDK in an Android or any client-side application.
