Android PermissionRequest Sample

This sample demonstrates how to use the PermissionRequest API to securely provide access to restricted system features (such as a camera or microphone) from within a WebView. In this example, a dialog is created to allow users to explicitly approve or reject each request.

Introduction

PermissionRequest can be used by setting up a custom WebChromeClient.

mWebView.setWebChromeClient(mWebChromeClient);

In you WebChromeClient implementation, you need to override onPermissionRequest. This method is called when the web content is requesting permission to access some resources, providing an opportunity to approve or reject the request. In this implementation, we display a dialog to allow the user to approve or reject any request. In other applications, you may want to implement a whitelist of allowed APIs. Also, override onPermissionRequestCanceled for handling cancellation of the PermissionRequest by the web content.

When the user confirms or denies the request, you can respond back to the web content by grant or deny respectively.

mPermissionRequest.grant(mPermissionRequest.getResources());

This sample provides the web content from the assets folder in the app. Since WebView is not allowed to use getUserMedia from a "file://" URL, the app uses the SimpleWebServer class to provide the content via "http://localhost".

Pre-requisites

  • Android SDK 27
