To allow permissions to the microphone, you need to set the webview implementation to a custom WebChromeClient using WebView#setWebViewClient :

WebView webView = ...;
webView.setWebChromeClient(new WebChromeClient(){
    @Override
    public void onPermissionRequest(PermissionRequest request){
        // Generally you want to check which permissions you are granting
        request.grant(request.getResources());
    }
})
