### 🚀 编译与使用指南
1. **编译**:
使用 NDK 中的 `aarch64-linux-android-clang` 编译,或者直接在手机端用带有开发环境的终端编译。确保目标架构是 **arm64-v8a**。
2. **准备环境**:
```bash
su
setenforce 0
chmod 777 /data/1/libJKMenu.so
chmod 777 /data/1/jk_injector
```
3. **运行监控**:
开启一个窗口执行你之前的日志过滤命令:
```bash
logcat -c && logcat -v color | grep -iE "JKMenu|Dobby|libJKMenu|dlopen" | grep -v "MediaProvider"
```
4. **执行注入**:
在游戏进入主界面(大厅)后运行:
```bash
/data/1/jk_injector
