Android Webview Camera And Microphone Permission Granted But Cannot Access

I am new to this Android webview. The app that i am creating has camera and microphone access. The permission for camera and microphone gets granted but when trying to open the ca

Solution 1:

You can not use a microphone and camera directly with webView for that you need to add extra permissions MODIFY_AUDIO_SETTINGS and also RECORD_AUDIO as well then only you will be able to access the features.

Add these permissions in the manifest file using

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />

then ask for permission using onPermissionRequest method in your webView client class in your case which is MyCustomWebChromeClient

Solution 2:

seems you have took runtime permission from user, but not granted for WebChromeClient please add following code, will solve problem

 webView.setWebChromeClient(new WebChromeClient(){
        @Override
        public void onPermissionRequest(final PermissionRequest request) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    request.grant(request.getResources());
                }
            });

        }

I too faced the same problem with Twilio Video Call sdk in a mobile web application opened inside WebView. While I spent good 4-5 hours trying various things from WebChromeClient in WebView and its events. Nothing worked for now. Had to resort to use some other alternate i.e. Chrome Custom Tabs. It is not exact substitude for WebView but was fit to our requirement for the time being.
