## SDK / Endpoint

### SDK

- `admob`
- `appsflyer`
- `firebase`
- `revenuecat`

### Endpoint candidates

- http://www.apache.org/licenses/
- http://tizen.org/system/model_name
- http://tizen.org/feature/platform.version

## Warnings

- apktool manifest decode skipped 2 split APK(s)
- binary AndroidManifest.xml decoded with apktool

## 下一步

- 真机/模拟器验证 onboarding、paywall、首个可感知价值和崩溃路径。
- 把 endpoint candidates 与 HAR / MITM / Frida 动态证据对齐，避免只凭静态字符串下结论。
- 多版本对比权限、SDK、endpoint、native libs 和资源路径变化。
- 订阅/广告 SDK 线索存在，后续需拆 paywall、free trial、退款和广告频率。
