        jcenter()
     }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:4.0.1'  //<---  ADD HERE

implementation 'com.google.firebase:firebase-core:16.0.0'
implementation  'com.loopj.android:android-async-http:1.4.9'
implementation project(':andia-debug')
```

```javascript
//###########      Example App build.gradle .  
apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.beto.andiaexample"
        minSdkVersion 22
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation project(':andia-debug')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'

    implementation project(':andia-debug')
}

```

## Update the Manifest file

Add the following settings to the manifest.xml file

```markup
    <uses-feature android:name="android.hardware.camera" android:required="true" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <meta-data  android:name="com.google.firebase.ml.vision.DEPENDENCIES" android:value="face" />
```

## Using the Library

Import the classes in your Activity

```java
import io.andia.example.ResultOnboarding;
import io.andia.example.SelfieValidator;
import io.andia.example.SelfieCallback;
import io.andia.example.ResultValidation;
```

In your Main Activity implement SelfieCallback

```java
public class MainActivity extends AppCompatActivity implements SelfieCallback {
     
     //activity Code
     
     // ...
     
    //Callback for OnBoarding.
    @Override
    public void resultOnBoarding(ResultOnboarding result) {
        Log.d("ANDIA", result.getMessage());

    }

    //Callback for Validation.
    @Override
    public void resultValidation(ResultValidation result){
        Log.d("ANDIA", result.getMessage());
    }
     
}
```

Call the OnBoarding Method.

```java
onboardingButton = (Button) findViewById(R.id.buttonOnboard);
        onboardingButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
            
                SelfieValidator validator = new SelfieValidator();
                validator.onboarding("API_KEY", MainActivity.this);
                
            }
        });
```

Call the Validation Method

```java
validateButton = (Button) findViewById(R.id.buttonValidate);
validateButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View arg0) {
        SelfieValidator validator = new SelfieValidator();
        validator.validation("API_KEY", "userid", MainActivity.this);
    }
});
```
