Answer 1

You can use third-party libraries. What you can't do, for example, is download a binary from your server at runtime and run that.

Answer 2

An unofficial answer from an official Google representative was that with Instant Apps, unlike normal apps, there is no technical way to run downloaded code, or load classes dynamically. For normal apps, the restriction is written in Play Store Developer Policy, and is enforced only on Play Store via standard security monitoring procedures.

unverified software

• In other words, only the signed apk and its contents are allowed.

arbitrary native code

• Everything must run from your apk or be provided by the framework.

load code dynamically

• Such as use of DexClassLoader to retrieve stuff that’s not already packaged with the apk.
