Crashes caused by newer system services being unavailable

[LightWayUp]

Bug description

The app crashes when:

• On Android 10 and 11, in LinkSheet navigate to Settings > Apps > Preferred apps
• On Android 9 and below, simply open LinkSheet

In functions, checks like if (AndroidVersion.AT_LEAST_API_31_S) are performed. However, fields are only annotated with @RequiresApi, which is a hint and does not prevent initialization.
Therefore, domainVerificationManager field in PreferredAppSettingsViewModel causes crash as Android can't find the class of the service:

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/content/pm/verify/domain/DomainVerificationManager;
(Obfuscated stack trace omitted)
Caused by: java.lang.ClassNotFoundException: android.content.pm.verify.domain.DomainVerificationManager
    ... 62 more

Similarly for roleManager field in MainViewModel:

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/app/role/RoleManager;
(Obfuscated stack trace omitted)
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.app.role.RoleManager" on path: DexPathList[[zip file "/data/app/fe.linksheet.nightly-66axovlUfdaoJtmvjdnJCA==/base.apk"],nativeLibraryDirectories=[/data/app/fe.linksheet.nightly-66axovlUfdaoJtmvjdnJCA==/lib/x86_64, /system/lib64]]
    at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:134)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:379)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:312)
    ... 62 more

There are more fields annotated this way in AppsWhichCanOpenLinksViewModel, but users can't reach that route below Android 12, so there's no impact there.

Thanks for the very detailed bug report, I thought the Android Gradle plugin does some magic at compile time to transform code using this annotation, but apparently it does not.
