## Important

**Note:** When you update the version of MyID SDK in your application, check the version of the
libraries in [dependencies](#12-setup-myid-android-sdk) and update them too!

## Getting started

### 1.1 Before you begin

Install or update Android Studio to its latest version.

The SDK supports API level 21 and above

Make sure that your app meets the following requirements:

- `minSdkVersion = 21`
- `targetSdkVersion = 33`
- `android.useAndroidX = true`

``` gradle
compileOptions {
  sourceCompatibility JavaVersion.VERSION_1_8
  targetCompatibility JavaVersion.VERSION_1_8
}
```

- myid-sdk-***.aar, has been provided to you, it contains SDK public interface and implementation.
  Archive name contains ever increasing release version number.

### 1.2 Setup MyID Android SDK

Create new project in AndroidStudio. Inside mobile application folder create new folder to store SDK
libraries (For example libs) and copy MyID SDK provided libraries.

Add reference to library to module **_build.gradle_**:

``` gradle
implementation(files("libs/myid-sdk-2.1.3-release.aar"))
```

**Note:** You can get `myid-sdk-2.1.3-release.aar` file
from [here](android-sample/app/libs/myid-sdk-2.1.3-release.aar)

After synchronization, You should be able to access to SDK classes from your source code.

MyID Android SDK also requires following libraries to be added:

``` gradle
dependencies {
    implementation(files("libs/myid-sdk-2.1.3-release.aar"))

    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-android:1.6.4")

    implementation("androidx.core:core-ktx:1.9.0")
    implementation("androidx.appcompat:appcompat:1.5.1")
    implementation("androidx.constraintlayout:constraintlayout:2.1.4")
    implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:2.5.1")
    implementation("androidx.lifecycle:lifecycle-runtime-ktx:2.5.1")

    def cameraVersion = "1.3.0-alpha01"
    implementation("androidx.camera:camera-camera2:$cameraVersion")
    implementation("androidx.camera:camera-lifecycle:$cameraVersion")
    implementation("androidx.camera:camera-view:$cameraVersion")
    
    implementation("io.ktor:ktor-client-android:2.1.2")
    implementation("io.sentry:sentry-android:6.7.0-alpha.1")
    
    // Use these dependencies if your app supports Google Play Services
    implementation("com.google.android.gms:play-services-mlkit-face-detection:17.1.0")
    implementation("com.google.android.gms:play-services-mlkit-text-recognition:18.0.2")
    implementation("com.google.android.gms:play-services-mlkit-barcode-scanning:18.1.0")

    // Use these dependencies if your app doesn't support Google Play Services
    implementation("com.google.mlkit:face-detection:16.1.5")
    implementation("com.google.mlkit:text-recognition:16.0.0-beta6")
    implementation("com.google.mlkit:barcode-scanning:17.0.2")
}
```

### 1.3 Permissions

Add following lines to the **_AndroidManifest.xml_**:

``` xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
```

## Usage

### With Activity Result API

``` kotlin
class ExampleActivity : AppCompatActivity(), MyIdResultListener {

    private val myIdClient = MyIdClient()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        startMyId()
    }

    private fun startMyId() {
        val organizationDetails = OrganizationDetails(
            phoneNumber = "1234567",
            logo = R.drawable.image_logo
        )
        
        val myIdConfig = MyIdConfig.builder(clientId = /* Your client id */)
            .withPassportData(passportData)
            .withBirthDate(dateOfBirth)
            .withSdkHash(sdkHash)
            .withExternalId(externalId)
            .withThreshold(threshold)
            .withBuildMode(MyIdBuildMode.PRODUCTION)
            .withEntryType(MyIdEntryType.AUTH)
            .withLocale(Locale("en"))
            .withCameraShape(MyIdCameraShape.CIRCLE)
            .withOrganizationDetails(organizationDetails)
            .withPhoto(false)
            .build()

        val intent = client.createIntent(activity = this, myIdConfig = myIdConfig)
        result.launch(intent)
    }

    private val result = takeUserResult(listener = this)
}
```

### With `onActivityResult` method

``` kotlin
class ExampleActivity : AppCompatActivity(), MyIdResultListener {

    private val myIdClient = MyIdClient()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        startMyId()
    }
    
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        myIdClient.handleActivityResult(resultCode, this)
    }

    private fun startMyId() {
        val organizationDetails = OrganizationDetails(
            phoneNumber = "1234567",
            logo = R.drawable.image_logo
        )
        
        val myIdConfig = MyIdConfig.builder(clientId = /* Your client id */)
            .withPassportData(passportData)
            .withBirthDate(dateOfBirth)
            .withSdkHash(sdkHash)
            .withExternalId(externalId)
            .withThreshold(threshold)
            .withBuildMode(MyIdBuildMode.PRODUCTION)
            .withEntryType(MyIdEntryType.AUTH)
            .withLocale(Locale("en"))
            .withCameraShape(MyIdCameraShape.CIRCLE)
            .withOrganizationDetails(organizationDetails)
            .withPhoto(false)
            .build()

        /*
           Start the flow. 1 should be your request code (customize as needed).
           Must be an Activity or Fragment (support library).
           This request code will be important for you on onActivityResult() to identify the MyIdResultListener.
        */
        myIdClient.startActivityForResult(this, 1, myIdConfig)
    }
}
```

### 1.1 Methods

Method | Notes | Default
--- | --- | ---
`withPassportData(value: String)` | Passport serial number or PINFL data | Optional
`withBirthDate(value: String)` | Date of birth in. Format: `dd.MM.yyyy` | Optional
`withSdkHash(value: String)` | 32 characters long string | Optional
`withExternalId(value: String)` | 36 characters long. Should match with UUID4 regex | Optional
`withThreshold(value: Float)` | The value can be in the range of `0.50` - `0.99` | 0.50
`withBuildMode(value: MyIdBuildMode)` | Build mode | MyIdBuildMode.PRODUCTION
`withEntryType(value: MyIdEntryType)` | Customizing the SDK Entry types | MyIdEntryType.AUTH
`withLocale(value: Locale)` | To set a specific locale | Locale("uz")
`withCameraShape(value: MyIdCameraShape)` | To set a specific camera shape | MyIdCameraShape.CIRCLE
`withOrganizationDetails(value: OrganizationDetails)` | Custom Organization Details | Optional
`withPhoto(value: Boolean)` | Return SDK face bitmap | false

**Note 1.1.** You can customize the screen for entering passport data and date of birth in your
application, in which case you can pass these parameters during initialization to the SDK, otherwise
the SDK requires the input of passport data and date of birth for user identification.

**Note 1.2.** If the `sdk_hash` is empty, blank or string with length other than 32 has been
provided, we will continue showing the credentials screen.

**Note 1.3.** If the `externalId` is not empty, has a length of 36 characters and corresponds to the
regular expression UUID4, we will display a [recommendation](images/screen01.jpg) screen in case the
sdk detects a blurry photo.

**Note 1.4.** `MyIdBuildMode` contains **DEBUG** and **PRODUCTION** modes.

- **DEBUG** is used to sandbox.
- **PRODUCTION** is used to production.

**Note 1.5.** `MyIdEntryType` contains **AUTH** and **FACE** types.

- **AUTH** is used to identify the user through the MyID services.
- **FACE** is used to detect a face and returns a picture (bitmap).

**Note 1.6.** `MyIdCameraShape` contains **[CIRCLE](images/screen03.jpg)**
and **[ELLIPSE](images/screen04.jpg)** types.

### 1.2 Handling callbacks

```kotlin
val myIdResultListener: MyIdResultListener = object : MyIdResultListener {
    override fun onSuccess(result: MyIdResult) {
        // Get face bitmap and result code

        val bitmap = result.bitmap
        val code = result.code
        val comparison = result.comparison
    }

    override fun onUserExited() {
        // User left the SDK
    }

    override fun onError(e: MyIdException) {
        // Get error message and code:

        val message = e.message
        val code = e.code
    }
}
```

| Attribute     |    Notes    |
| -----|-------|
| `onSuccess` | `MyIdResult` contains information about the face captures made during the flow, result code and comparison value. |
| `onUserExited` | User left the SDK flow without completing it. |
| `onError` | Some error happened. `MyIdException` contains information about the error message and code |

## Localization

The MyID Android SDK supports translations for the following languages:

- Uzbek      (uz) 🇺🇿
- English    (en) 🇬🇧
- Russian    (ru) 🇷🇺

By default, the Uzbek language is used. However, you can also call the `withLocale(Locale)`
method of the `MyIdConfig.Builder` configuration to set the language.

## Custom Organization Details

You can customize the SDK, for it to match your organization's brand book, by
providing `OrganizationDetails` object to `withOrganizationDetails` method. The object allows you to
customize following fields:

- *phoneNumber* - by default 712022202, which is MyID's call center. If you would like the customer
  to call your own call center, you can display your own phone number on the error screen, by
  providing it in this field ([sample](images/screen01.jpg)).
- *logo* - the drawable asset, that will be displayed on the input screen. If you would like to
  display your own logo on the top of the screen, this is the place to provide it. Make sure it fits
  the imageView element, which has the *240x60* size.
