Я пытаюсь внедрить приведенный ниже скрипт, используя frida
setImmediate(function() { //prevent timeout
console.log("[*] Starting script");
Java.perform(function() {
var bClass = Java.use("sg.vantagepoint.uncrackable1.a");
bClass.onClick.implementation = function(v) {
console.log("[*] onClick called");
// do nothing
}
console.log("[*] onClick handler modified")
})
})
Выдает приведенную ниже ошибку
Attaching...
