遍历hook Dex中的类

1. 创建DexFile

DexFile dexFile = new DexFile("/data/user/0/com.test/.cache/classes.jar")

2. 遍历拿出所有类名

Enumeration classNames = dexFile.entries();
while (classNames.hasMoreElements()) {
    final String className = classNames.nextElement();
    log("hook的类：" + className);
}

3. 找到类对象，进行hook

Class clazz = XposedHelpers.findClass(className, loadPackageParam.classLoader);

hook构造函数

XposedBridge.hookAllConstructors(clazz, new XC_MethodHook() {});

hook方法

XposedBridge.hookMethod(method, new XC_MethodHook() {});

4. 打印hook方法中的日志

try {
    Object[] args = param.args;
    if (args != null) {
        Method method = (Method) param.method;
        Log.e(TAG, "方法参数个数：" + args.length + " \n方法路径：" + method.toGenericString());
        int i = 0;
        StringBuilder sb = new StringBuilder();
        for (Object obj : args) {
            i++;
            String value;
            if (obj == null) {
                value = "is null";
            } else if (obj instanceof Context) {
                value = ((Context) obj).getClass().getName();
            } else if (obj instanceof Byte[]) {
                value = new String((byte[]) obj,
                        "utf-8") + " \nbyte:" + Arrays
                        .toString((byte[]) obj);
            } else if (obj instanceof Integer || obj instanceof Long || obj instanceof Boolean || obj instanceof String
                    || obj instanceof Double || obj instanceof Byte || obj instanceof Short || obj instanceof Character
                    || obj instanceof Float) {
                value = String.valueOf(obj);
            } else {
                value = obj.getClass().getName();
            }
            sb.append(" 参数").append(i).append("：").append(value).append("\n");
        }
        Log.e(TAG, "调用前：" + sb.toString());
    }
} catch (Exception e) {
}
