Android :: Opening Page With Javascript Pop Ups In Webview

Sep 27, 2010

I am very new to both android webkit and javascript. I have a web page with 3 links (say A,B,C). When I open that page on my PC browser(Chrome), and click on the links, A opens in the same browser window whereas B and C pops up a new window. In my application I am loading the original URL in a WebView. I have implemented my WebViewClient and overridden the shouldOverrideUrlLoading. I am getting the call to shouldOverrideUrlLoading whenever I click on A, but not getting it when I click on B or C?

Here is my file:

Android :: Webview Javascript Injection

Sep 17, 2010

I'd like to call a JavaScript function out of Java.

Well, the following source code works fine for me (http://

This is not called on the UI thread. Post a runnable to invoke


My problem now is to use a parameter for the JavaScript function.

Let's assume I've got some XML (just like AJAX somehow).

I need to escape it just like the iPhone / Objective-C command stringByEvaluatingJavaScriptFromString does.

Android :: Better JavaScript Debugging For WebView

Mar 4, 2009

I'm debugging a Javascript+HTML app. All the content is in ./assets.

The app works fine in Firefox, Safari and iPhone (over the web).

But in the WebView, I only get: D/WebCore (626): Console: undefined line: 0 source: undefined

I need to debug this code. Could I either: - enable more debugging in the WebView? though I think this needs to be done in the framework. or: - set up a desktop WebView equivalent where I can run a Javascript debugging tool?

I'm a real newbie to Android, and a pretty new user of JAVA but can follow an example / sample.

Android :: Can't Load Image In WebView Via Javascript

Jun 3, 2010

My app uses a WebView widget to load ads from Google AdManager. AdManager gives you an HTML snippet, which is 90% javascript to call their server for the image to load.

I put their html snippet into a string and use String.format to add in several variables that AdManager requires.

I enable javascript on the WebView (webView.getSettings().setJavaScriptEnabled(true);)

I load the string into the WebView (webView.loadData(myString, "text/html", "UTF-8");

result: the ad never loads (although the WebViewClient shows serveral .js resources loading).

If I take that exact string and create a file and then use webView.loadUrl("file:///android_asset/test.html"), the image loads properly.

Why would loadUrl work but loadData does not?

I've verified that javascript is running. I injected a little script to write out a text string and it works.

Android :: JavaScript Sometimes Doesn't Work In Webview

Jul 22, 2010

I put a webview in my application to visit a webpage which includes some javascript functions, my purpose is when users click a link in the webpage, it will start a new activity in the application. I've written "webSettings.setJavaScriptEnabled(true);" in my source codes.

It works well in most of the time, however sometimes it doesn't work, there is no response when users click, and I don't know why because the environment is not changed at all.

Android :: WebView Playing Audio With Javascript

Sep 25, 2010

I'm trying to very quickly port over an html application with plays sound (with soundmanager2) to a native android app using WebView. From my research, I haven't seen any evidence that sound, such as mp3s, can be played via javascript or any other methods using WebView.

My goal now is to quickly port over the html app and then eventually create a truely native application without using WebViews.

If anyone has been able to successfully implement playing audio using WebViews and Javascript or if this is just not possible at this time.

Android :: Webview - Possible To Execute Javascript From Java Synchronously

Apr 6, 2009

I am writing a hybrid web/native app and ran into issue. My app downloads a music file via Java code, and needs to update a Javascript download progress bar in the WebView in real time.

My understanding is the only way to call Javascript from Java is via the WebView's loadUrl method.

Android :: WebView - Documentation Of JavaScript And Java Interaction

Sep 30, 2010

I have found that there is a significant lack of documentation of WebView's ability to communicate with Java via WebView.addJavaScript() method. First, the debug document appears to no longer work. Second, what object types should we expect when going to and from JavaScript. I have done some trial and error and it appears that complex types can cross the boundary, for example java.util.Vector. However when a Java method returns a byte array to JavaScript it has a type of undefined and I have been unable to coerce it to any other type. Finally, there is great potential with this interface and with some more attention we could go far.

Android :: Use WebView To Evaluate Javascript String And Return Value

Dec 1, 2009

Given that scripting is not natively supported in Android and wrapping libraries like javax.script.ScriptEngine into your app will make it too large, is it possible to send a javascript string to an invisible WebView and have it evaluate the string and return you the results (another string)?

I want to go this route because I want to save all my scripts to disk so my app can remain small.

Android :: Javascript Problem With Webview Runing Under HTC Desire

May 31, 2010

I am developing an application with Webview. The web app that runs inside the Webview is loaded from internet, and it is a single HTML file. I use javascript for showing and hiding the divs, depending on the section button the user had tapped on.

The problem is simple: after a little while (this time period seems to be random), javascript stops working inside the Webview object. Then, after a few seconds (10-30 seconds), javascript works again. It doesn't work any javascript. Nothing.

The strange thing is that the problem only happens when the application runs in a HTC Desire. I tested it in two different HTC Desire, and the problem happens in both devices. I tested it in a Motorola Milestone, in a HTC Hero and under emulator (1.5,1.6,2.1) and the application works fine, no error at all.

The problem happens using Wifi or mobile network.

I tried the debugger, but "Dev tools" crashes when I tap in "Development Settings". I also tried to compile the application for debugging under Eclipse, but adb does not show me info about the WebView object.

The HTC Desire firmware version is 2.1-update1. Kernel version: 2.6.29-3cb3dfbf. Build number: Webkit 3.1

Android :: Javascript Execution Stops On Scrolling Or Zooming Any Page

Jun 8, 2010

I am about to develop a web application for smart phones. This app uses some JavaScript code. While testing it on Android devices (Hero, Desire) I noticed that all JavaScript timers immediately stop when the page is moved or zoomed. They never continue. Let's say you have a site which displays web camera images with 5 fps. As soon as you move this page (I mean scroll with finger) the web camera image will never be loaded again. So you can't center or zoom the image at all without stopping the stream. This behaviour is 100% reproducible on all Android devices I tested (1.5, 2.1). It does not appear on an iPhone which continues execution after moving stopped fine.

Android :: Detect Click On HTML Button Through Javascript In WebView

Oct 31, 2010

I'm not highly familiar with javascript but I think this is the best way to accomplish my purpose. If not, please correct me. I have a licence text 2 buttons at the end. All of this is written in HTML in a WebView because there are some links in the licence. Now, I want that when the user clicks the "ok" button in the WebView, this triggers some javascript or listener that I can grab in Java to fire an Intent to go forward in the application. (The cancel button would do the opposite, but if I know how to do one, I can do the other. Does this rings any bell to someone? Any explanation or sample code is welcome.

Android :: Get Web Page Contents From A WebView?

Mar 4, 2010

On Android, I have a WebView that is displaying a page. How do I get the page source without requesting the page again?

It seems WebView should have some kind of .getPageSource() method that returns a string, but alas it does not.

If I enable javascript, what is the appropriate javascript to put in this call to get the contents? code...

Android :: Android WebView Not Loading A JavaScript File But Android Browser Loads It Fine

Jun 3, 2010

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebSettings;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class myKMB extends Activity {
I already have JavaScript on the web browser on, the problem is the web view is acting to different from the web browser.
