--- Examples:

---   local my_string_builder = StringBuilder("hi")

---
--- @param class_name string
--- @return Class
function import(class_name) end

--- Examples:
---   local Runnable = import("java.lang.Runnable")
---   local my_runnable = object(Runnable, {
---     run = function(this)
---     
---     end
---   })
---   my_runnable:run()
---
--- @param class Class
--- @param proxy table<string, function>
--- @return Class

--- Exampels:
---   local View = import("android.view.View")
---   local Context = import("android.content.Context")
---   local AttributeSet = import("android.util.AttributeSet")
---
---   hook {
---     class = View,

---       Context,
---       AttributeSet,
---       int
---     },
---     after = function(this, params)
---       -- Add your own logic after constructor is called
---

---   local Canvas = import("android.graphics.Canvas")

---       local canvas = params[1]
---       -- Using canvas to draw anything you want
---     
---     end
---   }
---
--- @param config table This table accepts the following keys
---                     - class: (Class) The hook target.
---                     - returns: (nil|Class) The method return type.
---                     - method: (string) The method name.
---                     - params: (nil|table) The method argument types, can be nil if there is no argument.
---                     - before: (nil|function) Executed before the method is called.
---                     - after: (nil|function) Executed after the method is called.
---                     - replace: (nil|function) A simple version of `before`, use to rewrite the whole method.
