Android Launch Browser from App to handle external URLs

Upon googling for this one, I found some good relevant links on stack overflow as well as the android webview documentation, but no singular solution that tied everything together.

First, I created a custom WebViewClient class. Note that this is optional as you can do inline class declarations in this environment.

package com.example.testapp;

import android.app.Activity;
import android.content.Context;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.content.Intent;

public class MyWebViewClient extends WebViewClient {
@Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url != null && url.startsWith('http://192.168.1.101')) {
            return false;
        } else {
        	view.getContext().startActivity(
                    new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
            return true;
        }
    }
}

Then, in the main activity, use code within onCreate to support for multiple windows and to set the web view client to your own custom client.

package com.example.testapp;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Menu;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.view.KeyEvent;
import android.webkit.WebChromeClient;
import android.net.Uri;

public class MainActivity extends Activity {

	private WebView webView;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	final Context context = this;
    	
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    	webView = (WebView) findViewById(R.id.webView1);
    	webView.getSettings().setJavaScriptEnabled(true);
    	
    	webView.getSettings().setSupportMultipleWindows(true);

    	webView.setWebViewClient(new MyWebViewClient());
    	webView.loadUrl('http://192.168.1.1/login.aspx');
    }

If you want to use an inline class declaration instead of defining a seperate mywebviewclient class, you can also use something like:

    	webView.setWebViewClient(new WebViewClient() {
    	      @Override
    	      public boolean shouldOverrideUrlLoading(WebView view, String url) {
//etc, same code as above
    	      }
});

If you have not already addressed the question of handling the android back button within your webview, the android documentation has a good quick simple code reference on how to accomplish this.

Enjoy. 🙂
