NativeScript Android Advanced Webview

This plugin will allow you to use some of advance feature of Android Webview. This plugin is using following library

Android: Android-AdvancedWebView

Note: I am not an expert of neigher iOS nor Android. So, please contribute if you think something you can do for better :)

Installation

tns plugin add nativescript-android-advanced-webview

Usage (Angular)

import { registerElement } from "nativescript-angular";
registerElement("AdvanceWebview", () => require("nativescript-android-advanced-webview").AndroidAdvancedWebview);

ngAfterViewInit() {
let advanceWebview: AndroidAdvancedWebview = this.page.getViewById("webview");

let optons: AndroidAdvanceWebviewOptions = {
android: {
setGeolocationEnabled: false,
setCookiesEnabled: true,
}
}

advanceWebview.setWebviewOptions(optons);

advanceWebview.on("started", function (res) {
console.log("started");
console.dir(res);
})
advanceWebview.on("finished", function (res) {
console.log("finished");
console.dir(res);
})
}

HTML:

<AdvanceWebview id="webview" src="https://google.com"></AdvanceWebview>

Advance Configuration for WebViewClient or WebChromeClient class. You will need to implement your own customized override methods. You can do almost everything here :). You can install tns-platform-declarations for avoiding typescript error. Please check the demo for more details.

advanceWebview.setUpWebViewClient(new MyWebViewTestClient()); //android.webkit.WebViewClient class
advanceWebview.setUpWebChromeClient(new MyWebChromeClient()); //android.webkit.WebChromeClient

Class can be extend like this:

export class MyWebViewTestClient extends android.webkit.WebViewClient {

constructor() {
super();
return global.__native(this);
}
public onPageStarted(view: android.webkit.WebView, url: string, favicon: android.graphics.Bitmap): void {
console.log("onPageStarted: " + url);
}
public onPageFinished(view: android.webkit.WebView, url: string): void {
console.log("onPageFinished");
}
public onReceivedError(view: android.webkit.WebView, request, error): void {
console.log("onReceivedError");
}
}

export class MyWebChromeClient extends android.webkit.WebChromeClient {

constructor() {
super();
return global.__native(this);
}

public onReceivedTitle(view: android.webkit.WebView, title: string): void {
console.log(title);
}

public onPermissionRequest(request: any): void {
console.log("Permission asked !!");
request.grant(request.getResources());
}
}

API

You can get more events by extending WebViewClient or WebChromeClient class like onReceivedTitle, onPermissionRequest (for allowing microphone) etc. This plugin also has some limitations too. You can check the library repository for more details.
