## 🔐 Security & Signing

### Optional: APK Signing

To sign release APKs, add these GitLab CI/CD variables:

**Settings → CI/CD → Variables:**
- `KEYSTORE_FILE` - Base64 encoded keystore
- `KEYSTORE_PASSWORD` - Keystore password
- `KEY_ALIAS` - Key alias (e.g., "silverdroid")
- `KEY_PASSWORD` - Key password

**Generate keystore:**
```bash
keytool -genkey -v -keystore silverdroid.keystore \
  -alias silverdroid -keyalg RSA -keysize 2048 -validity 10000

base64 -w 0 silverdroid.keystore > keystore.base64
```

Then update `.gitlab-ci.yml` to use signing (see GITLAB_CICD_SETUP.md).

## 📈 Monitoring

### Pipeline Status Badge

Add to README.md:
```markdown
[![Pipeline](https://gitlab.silverlabs.uk/SilverLABS/silverdroid/badges/main/pipeline.svg)](https://gitlab.silverlabs.uk/SilverLABS/silverdroid/-/pipelines)
```

### Check Pipeline Status via API

```bash
curl "https://gitlab.silverlabs.uk/api/v4/projects/SilverLABS%2Fsilverdroid/pipelines" \
  --header "PRIVATE-TOKEN: glpat-wqUcD7mg53F1mgM-N-PdiW86MQp1OjEH.01.0w074ox93"
```

### Download Latest APK via API

```bash
curl -L "https://gitlab.silverlabs.uk/api/v4/projects/SilverLABS%2Fsilverdroid/jobs/artifacts/main/download?job=build:debug" \
  --header "PRIVATE-TOKEN: glpat-wqUcD7mg53F1mgM-N-PdiW86MQp1OjEH.01.0w074ox93" \
  -o silverdroid-debug.zip
```

## 🐛 Troubleshooting

### Pipeline Doesn't Start
- Check GitLab Runner is active: Settings → CI/CD → Runners
- Verify `.gitlab-ci.yml` is in root directory
- Check syntax: CI/CD → Pipelines → CI Lint

### Build Fails: "Gradle not found"
- Runner may not have Android SDK
- Using `mingc/android-build-box` image fixes this
- Check `image:` in `.gitlab-ci.yml`

### Can't Download Artifacts
- Check artifact expiration hasn't passed
- Verify job completed successfully (green checkmark)
- Try direct download URL (see above)

### Runner Out of Disk Space
```bash
# On GitLab server
gitlab-runner exec docker cleanup
docker system prune -a
```

## 🎯 Next Steps

1. **Push to GitLab**
   ```bash
   ./push-to-gitlab.sh  # or .ps1 on Windows
   ```

2. **Watch Pipeline Run**
   Visit: https://gitlab.silverlabs.uk/SilverLABS/silverdroid/-/pipelines

3. **Wait for Build** (~5-8 minutes)

4. **Download APK**
   Go to: Jobs → build:debug → Browse → app/build/outputs/apk/debug/

5. **Install on Device**
   ```bash
   adb install app-debug.apk
   ```

6. **Test Admin Panel**
   Launch app → Should load admin.dark.side
