Added in API level 1

Handles the method which was originally invoked on the proxy instance. A typical usage pattern follows below: 

          public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
     //do some processing before the method invocation

     //invoke the method
     Object result = method.invoke(proxy, args);

     //do some processing after the method invocation
     return result;
 }

Parameters
proxy the proxy instance on which the method was invoked
method the method invoked on the proxy instance
args an array of objects containing the parameters passed to the method, or null if no arguments are expected. Primitive types are boxed.
Returns
  • the result of executing the method. Primitive types are boxed.
Throws
Throwable the exception to throw from the invoked method on the proxy. The exception must match one of the declared exception types of the invoked method or any unchecked exception type. If not then an UndeclaredThrowableException is thrown
