非法的参数。
详见:https://github.com/iqiyi/xHook/blob/master/libxhook/jni/xh_errno.h
from xhook.
只需要hook libxhookmethod.so就可以了,注意下正则的语法:
xhook_register(".*/libxhookmethod\\.so$", "__android_log_print", my_hook_log_print, NULL);
xhook_refresh(1);
from xhook.
好的 谢谢你!这锻还是 报1002 ,我去稍微 看看 里面 源码!看看 哪里 还有问题!有问题的话 我在来请教你
from xhook.
好的,不客气。
from xhook.
xhook_register(".*/libxhookmethod\.so$", "__android_log_print", my_hook_log_print, NULL);
我这个地方 返回为0表示成功了,但是hook 没有成功
XHook.getInstance().init();
XHook.getInstance().doHook();
然后按钮点击事件
JniXhookMethod.log();
xhook c代码
static int my_hook_log_print(int prio, const char* tag, const char* fmt, ...)
{
va_list ap;
char buf[1024];
int r;
snprintf(buf, sizeof(buf), "[%s] %s","来来来底层被串改了", (NULL == fmt ? "" : fmt));
va_start(ap, fmt);
r = __android_log_vprint(prio, "czg", buf, ap);
va_end(ap);
return r;
}
JNIEXPORT void JNICALL Java_com_yztc_devicetool_nativehook_NativeHandler_doHook
(JNIEnv * env, jobject j_obj){
int c = xhook_register(".*/libxhookmethod\\.so$", "__android_log_print", my_hook_log_print, NULL);
xhook_refresh(1);
__android_log_print(ANDROID_LOG_VERBOSE,"czg","我hook初始化了%d",c);
}
JnixHookMethod 的c代码
JNIEXPORT void JNICALL Java_com_yztc_devicetool_nat_JniXhookMethod_log
(JNIEnv * env, jclass object)
{
__android_log_print(ANDROID_LOG_VERBOSE,"czg","我是原始的log");
}
不知道哪里 有没有写对?
from xhook.
大神,顺带问一下 ,你的这个开源代码 能修改底层的所有 api方法吗?设备信息,mac ,serial码之类的?
from xhook.
先改成
xhook_refresh(0);
试试吧,0
表示同步执行hook操作,这样refresh返回时hook肯定执行完了。还是不行的话,就打开xhook的调试输出(xhook_enable_debug(1);
),看下logcat输出。
from xhook.
你可以大致了解下PLT/GOT hook的原理,只能hook动态库之间的调用。hook设备信息/MAC获取这些我没试过,如果能找到合适的hook点,应该是可以实现的。

好的谢谢
