//第一步找到类
//找到方法，如果是私有方法就要setAccessible设置访问权限
//invoke主动调用或者set修改值(变量)
Class democlass = Class.forName("com.zj.wuaipojie2023_3.MainActivity", false, loadPackageParam.classLoader);
Method demomethod = democlass.getDeclaredMethod("decrypt");
demomethod.setAccessible(true);
demomethod.invoke(clazz.newInstance());
}
});
}
}
}
以上是报错代码 final Class clazz = XposedHelpers.findClass("com.zj.wuaipojie2023_3.MainActivity",loadPackageParam.classLoader); 报错
后为第二个问题
主动调用
在正己讲解 第八课课最后的新年解答题 中
Class clazz = XposedHelpers.findClass("com.zj.wuaipojie2023_3.MainActivity",lpparam.classLoader);
XposedHelpers.callMethod(clazz.newInstance(),"decrypt","hnci}|jwfclkczkppkcpmwckng\u007f", 2);
无法实行主动调用 代码并未错 不知为何无法调用
