Android WebView

You can embed the Web Client in a native Android WebView.

Permissions and Settings

Make sure that these required permissions are granted:

• android.permission.INTERNET

  For remote resources access.

• android.permission.CAMERA

  For camera capture.

• android.permission.READ_EXTERNAL_STORAGE

  For upload functionality.

The following settings are required for the native WebView for Android:

• Enable javaScriptEnabled

  Tells the WebView to enable JavaScript execution.

• Allow allowFileAccess

  Enables file access within WebView.

• Allow allowFileAccessFromFileUrls

  Sets whether JavaScript running in the context of a file scheme URL should be allowed to access content from other file scheme URLs.

• Allow allowUniversalAccessFromFileUrls

  Sets whether JavaScript running in the context of a file scheme URL should be allowed to access content from any origin.

• Allow allowContentAccess

  Enables content URL access within WebView.

• Allow javaScriptCanOpenWindowsAutomatically

  Tells JavaScript to open windows automatically.

• Enable domStorageEnabled

  Sets whether the DOM storage API is enabled.

• Do not allow mediaPlaybackRequiresUserGesture

  Sets whether the WebView requires a user gesture to play media.

Embedding the Required Script

To allow Jumio to identify the user runtime environment, you will need to embed a required script that sets flag __NVW_WEBVIEW__ to true to interact with the WebView window object. For details, see the sample code below.

Use of iProov

Be aware that if iProov is included in your workflow it is necessary to extend the WebChromeClient class to implement a custom view, in order to handle certain iProov full screen requirements.

See WebviewFragment.kt, specifically WebChromeClientFullScreen inner class.
