# Android Target API Level & Policy Compliance
|
|
|
|
## 1. Target API Level Verification
|
|
|
|
| Setting | Value | Status |
|
|
|---------|-------|--------|
|
|
| `targetSdk` | 36 (Android 16) | ✅ |
|
|
| `compileSdk` | `release(36) { minorApiLevel = 1 }` | ✅ |
|
|
| `minSdk` | 26 (Android 8.0) | ✅ |
|
|
| AGP Version | 9.1.1 | ✅ |
|
|
|
|
The app targets API level 36 which is the latest available. The `compileSdk` uses the modern AGP 9.x declarative API with `release(36)` syntax.
|
|
|
|
## 2. Deprecated API Usage Audit
|
|
|
|
### Fixed Issues
|
|
|
|
| File | Issue | Resolution |
|
|
|------|-------|------------|
|
|
| `SecurityChecker.kt` | `PackageManager.getInstallerPackageName()` deprecated in API 33 | Replaced with `getInstallSourceInfo()` on API 33+ with deprecation fallback |
|
|
| `SecurityChecker.kt` | `PackageManager.GET_SIGNATURES` deprecated in API 28 | Already guarded with SDK version check + `@Suppress("DEPRECATION")` |
|
|
| `SecurityChecker.kt` | `PackageManager.getInstalledPackages(0)` deprecated in API 33 | Already using `PackageInfoFlags.of(0)` on API 33+ with deprecation fallback |
|
|
| `SecurityChecker.kt` | `packageInfo.signatures` deprecated in API 28 | Already guarded with SDK version check + `@Suppress("DEPRECATION")`; type mismatch fixed |
|
|
|
|
### Already Using Modern APIs
|
|
|
|
| API | Modern Alternative | Status |
|
|
|-----|-------------------|--------|
|
|
| `BiometricPrompt` | ✅ Already used instead of deprecated `FingerprintManager` | ✅ |
|
|
| `WorkManager` | ✅ Already used instead of direct `JobScheduler` | ✅ |
|
|
| `NotificationChannel` | ✅ Already configured via `NotificationChannelManager` | ✅ |
|
|
| `FileProvider` | ✅ Already used (referenced in manifest/data_extraction_rules) | ✅ |
|
|
| `EncryptedSharedPreferences` | ✅ Already used via `SecureStorageManager` | ✅ |
|
|
| `NotificationCompat` | ✅ Already used for backward-compatible notifications | ✅ |
