Setup Accura Face Liveness

Add following code in Manifest.

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

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

<application
    ...
    android:networkSecurityConfig="@xml/network_security_config"
    >

 </application>
 
Note : 'android:networkSecurityConfig="@xml/network_security_config"' setup will permit clear text traffic   

Add following code to your Application class or MainActivity for hostname verification

new HostnameVerifier() {
    @Override
    public boolean verify(String hostname, SSLSession session) {
        HostnameVerifier hv = HttpsURLConnection.getDefaultHostnameVerifier();
        return hv.verify("your url host name", session);
    }
};
