Question

What would be the best way to implement Aspect-oriented programming (AOP) in an Android application?

Would it be efficient with the mobile battery?

Answer 1

It depends in how it is implemented.

For instance, AspectJ’s compile-time weaving would work on android but runtime weaving do not.
Android does not support bytecode generation.

Check the Guice wiki:

Behind the scenes, method interception
is implemented by generating bytecode
at runtime. Guice dynamically creates
a subclass that applies interceptors
by overriding methods. If you are on a
platform that doesn’t support bytecode
generation (such as Android), you
should use Guice without AOP support.
