### Android Manifest Permission Management

Source: https://api-reference-sdk.mattr.global/mobile-credential-verifier-android/latest/index

Demonstrates how to manage Android permissions in the manifest file using manifest merger rules. Shows how to remove specific permissions or attributes like `maxSdkVersion` to control their inclusion in the final APK.

```xml
<uses-permission  
    tools:node="remove"  
    android:name="android.permission.INTERNET" />
```

```xml
<uses-permission  
    tools:remove="android:maxSdkVersion"  
    android:name="android.permission.ACCESS_FINE_LOCATION" />  
<uses-permission  
    tools:remove="maxSdkVersion"  
    android:name="android.permission.ACCESS_COARSE_LOCATION" />
```

### Inspect APK Manifest with AAPT

Source: https://api-reference-sdk.mattr.global/mobile-credential-verifier-android/latest/index

Uses the Android SDK tool `aapt` to inspect the merged manifest of an APK. This command helps in verifying the permissions and features included in the final application package.

```shell
$ aapt d badging path/to/your.apk
```

Details significant API changes and additions to the `MobileCredentialVerifier` class across different SDK versions. This includes method renames, removal of deprecated functions, and new features like NFC engagement and simplified singleton patterns.

```APIDOC
SDK Version 4.0.0:
- `deinitialize` method made idempotent.
- `deinitialize` method made non-throwing.

SDK Version 3.0.0:
- Spelling standardization: `initialise` renamed to `initialize`, `deinitialise` to `deinitialize`.
- Exception renaming: `SdkNotInitialisedException` to `SdkNotInitializedException`, `StorageInitialisationException` to `StorageInitializationException`.
- Proximity presentation sessions management enhancements:
  - `ProximityPresentationSession` class removed.
  - `MobileCredentialVerifier.getCurrentProximityPresentationSession` removed.
  - `MobileCredentialVerifier.createProximityPresentationSession`:
    - Shares session creation result via callback.
    - Returns immediately, establishes session asynchronously.
  - `ProximityPresentationSession.requestMobileCredentials` replaced by `MobileCredentialVerifier.sendProximityPresentationRequest`.
  - `ProximityPresentationSession.terminateSession` replaced by `MobileCredentialVerifier.terminateProximityPresentationSession`.
  - `MobileCredentialVerifier` singleton simplification:
    - Now a Kotlin object.
    - `MobileCredentialVerifier.getInstance` removed.
  - Presentation session lifecycle observable via `ProximityPresentationSessionListener`.
- New features:
  - NFC device engagement support (Android holder devices):
    - `MobileCredentialVerifier.registerForNfcDeviceEngagement` added.
    - `MobileCredentialVerifier.deregisterForNfcDeviceEngagement` added.
  - `MobileCredentialVerifier.deinitialize` API added.

SDK Version 2.0.0:
- Removed `statusInfo` from `MobileCredentialPresentation`, `MobileCredential`, and `MobileCredentialMetadata`.
- Removed `deviceKeyId` from `MobileCredential` and `MobileCredentialMetadata`.
