APIs expose handle and symbol table to share objects between layers. Understand ownership, lifecycle and native integration risks.

Direct answer

O ARCore 1.54 adicionou ArCoreNativeInterop, getNativeHandle() e getSymbolTable() para compartilhar ou transferir propriedade de objetos ARCore entre Java e C++. A capacidade reduz cópias e pontes improvisadas em aplicações híbridas, mas torna explícitas responsabilidades de ownership, thread, validade e liberação. Errors can cause use after release, leaks, or crashes that are difficult to reproduce.

Handle nativo não é uma cópia independente

Define who owns the object, for how long and on which layer it will be released.

Thread e sessão precisam de contrato

Calls outside the expected thread or session may break invariants. Centralize acesso e documente fronteiras.

Tabela de símbolos reduz acoplamento direto

Resolving functions dynamically helps integration, but requires version checking and fallback when a symbol does not exist.

Falhas nativas pedem observabilidade

Record versions, device, session state, and last boundary crossed between Java and C++.

Nexus Reading

Use interop to reduce overhead with just ownership contracts, stress testing and memory sanitization.

FAQ

Para que serve getNativeHandle()?

To access the native representation of an ARCore object as per the API contract.

É seguro guardar o handle indefinidamente?

No. Validity depends on the life cycle and property of the object.

When is it worth using?

When C++ logic or libraries need to operate directly on ARCore objects and the gain justifies the complexity.
