Question

我正在尝试在类的构造函数上应用一个方面。我已经创建了一个带有方面的编译类的jar文件。 noq我想将该jar文件转换为.dex文件。但转换它时显示异常：

F:\sachin\Tools\ADT_Bundle\adt-bundle-windows-x86\sdk\platform-tools>dx --dex --
output=classes.dex Yepme_jar_with_aspect_on_setText.jar

EXCEPTION FROM SIMULATION:
local variable type mismatch: attempt to set or access a value of type int using
 a local variable of type pak.HookYepmeAspect. This is symptomatic of .class tra
nsformation tools that ignore local variable information.

这是我的方面代码：

public aspect ABC{

        pointcut pkt_findviewbyid(int id):call(View android.app.Activity.findViewById(int)) &&  args(id);

        View around(int id):pkt_findviewbyid(id) && within(com.yepme.*)
        { }
 }

我的观察是，每当我将int参数传递给任何切入点时，都会产生此错误，但我不知道为什么它会像这样。所以请告诉我这个错误的解决方案是什么...提前谢谢。

Answer 1

我知道这个回复为时已晚，但它比保持问题没有答案要好。经过大量的研究，我发现带有参数的周围切入点，如果第一个参数是int，那么在创建.dex时它会给出错误。因此，为了解决这个问题，我将第一个参数作为目标对象并将其作为目标传递。

void around(Object target, int arg1,String arg2): call(* *.foo(int,String)) && args(arg1,arg2) && target(target)
{
    <code body>
}

它对我有用..
