AndroidManifest.xml 들어가면 administrator 설정되어있는걸 볼 수 있고,

```
<activity
            android:name="app.beetlebug.ctf.b33tleAdministrator"
            android:exported="true"/>
        <activity
```

adb가 자동 실행되지 않아 절대경로로 나온 주소를 실행 후 관리자 권한으로 플래그를 구할 수 있다.

```
C:\Users\after\AppData\Local\Android\Sdk\platform-tools\adb.exe shell am start -n app.beetlebug/.ctf.b33tleAdministrator
```
