# openeuicc-bridge

An Android ContentProvider that exposes [OpenEUICC/EasyEUICC](https://gitea.angry.im/PeterCxy/OpenEUICC) LPA functionality via ADB, enabling programmatic eSIM profile management.

## Build & Install

```bash
./build+install.sh
```

The script:
1. Compiles [`LpaProvider.java`](https://github.com/Laiteux/openeuicc-bridge/blob/main/src/im/angry/openeuicc/bridge/LpaProvider.java) to `.class` files
2. Converts to `.dex` using d8, then disassembles to smali
3. Injects smali into the decompiled EasyEUICC APK
4. Rebuilds and signs the APK with [9eSIM Community Key](https://github.com/9esim/9eSIMCommunityKey)
5. Installs via `adb install`

**Requirements:** apktool, adb, java, javac

**Included:** Build tools in `tools/`, Java dependencies in `deps/`
