Linting errors hinder ability to build repository

Nobody has claimed this yet.

## The Issue
I keep getting linting errors when trying to build this app. I'm fairly sure it's not just me. This forces me to have to put `lintOptions {
abortOnError false
}` in the `android` options of `app/build.gradle` to be able to build and install the app. Can these issues be fixed or should this workaround be added to source?

### Steps to reproduce
1. Clone repo
2. Open it in Android Studio
3. Set up stuff
4. Try to run

### Expected behaviour
I should be able to build the project without having to do a workaround.

### Actual behaviour
I have to do a workaround so I can build the project.

## System Configuration
- Device: pop!os latest

### Acceptance Criteria
1. Workaround added to source OR linting errors fixed

Start by reproducing the build in Android Studio and inspect the reported findings in lint-results.txt. Review app/build.gradle and determine whether the listed lint errors can be fixed; done means the project builds without the workaround, or the workaround is added to the source as specified by the acceptance criteria.
