Android :: WebView For Form Based Local AJAX Application

Feb 18, 2009

I'm thinking of using WebView as a container for "Form" based JavaScript+DHTML applications. This is simple fill-out-forms like you have on the web, but now on mobile like for note taking, order taking, and the like.This is to allow web developers to build the bulk of the application - Javascript will perform validation, computations, etc.On the Java side, I only need to implement database CRUD operations, and a ListView to scroll over the forms.To minimize the learning curve on the JavaScript side, I've been thinking on how to emulate AJAX calls so that the web developers don't need to learn new methods to call on the JavaScript-Java bridge. Of course this isn't possible using XMLHttpRequest, so I'm thinking of adapting JQuery or other Javascript libraries for this purpose.

Android :: Intercept AJAX Call From WebView

Oct 15, 2010

I want a HTML/javascript application, running in a WebView, to make AJAX calls that are handled by the Java code. Ideal would be to just intercept the call (easy, just use shouldOverrideUrlLoading()) and 'return' some data. However, I don't find a way to 'return' a response to the WebView, other than calling a javascript function using loadUrl(). This will not work for me, as the HTML/js app is a drop-in application which I don't control. As far as the HTML/js app concerns, it just does an AJAX call and receives some data back.

Android :: How To Access HTML Form Data POSTed Through A WebView?

Aug 31, 2010

I've started to write an app which provides the user with an HTML form via a WebView. As the form is not under my control, the data filled in may be sent as either GET or POST request. My app is required to capture the transported form data, that is, get a hold on what was entered into the form fields. Using an adequate callback from WebViewClient such as onPageLoaded(), it is easy to capture form data from a GET request. However, I cannot find any appropriate method to allow the same for POSTed data, i.e., be able to access the HTTP POST message body containing the form data. Am I missing a relevant callback here or is there simply no way to accomplish the specified goal with the given API (even the latest level 8)?

Android :: Avoid User Input In A Field Of Form In A WebView?

Nov 1, 2010

When I load the touch Facebook login page in the webview, I want that the email field to be set to a value and it can't be modified and to accomplish that I have inserted a JavaScript code in the webview disabling that element. All works fine until I want to click the login button because the page refreshes instead of submit the login info. I've noticed that if I don't disable the item, the login button works fine but I don't know why occurs that.

What can be the problem? I've thought another way to make it works: Whenever the user try to modify the email field ignore whatever he do, but I think this is a less professional way to fix that.

Android :: Publish An Application Update On Android - Market Without Deleting Local Database And Local Files

Nov 11, 2010

I published an application that stores data in a local database.

Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.

I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?

If so, how can I avoid this in my code?

Android :: How To Mix External / Local Content In WebView?

Oct 12, 2009

I am trying to create a hybrid Android app which pulls HTML content from a web server and renders it in a WebView. However, I also want the external HTML to be able to reference images that are packaged within the android app. I realize that currently it is not possible to do something like <img src="file:///my_image.jpg" /> in the HTML. I have seen discussions of using the ContentProvider to create name spaces in the html, however all of these examples seem to assume that the actual html page is also on the device and tend to use WebView.loadData(). So, is there someway that it is possible to do this? The main goal is to package all the application images/css in the android app, but put the bulk of the application on an external server that returns the actual markup.

Android :: PNG Quality In WebView Based App

May 10, 2010

I am using WebView to display html content in an app. One of the pages has a rather large PNG image. The image is large and detailed on purpose because the idea is to use it as a map and allow users to zoom in to see the detail. Unfortunately, when the image is displayed with WebView, the quality is horrific. I am assuming that WebView is attempting to do some image optimization to reduce the size of the graphic. Is there anyway to prevent it from doing this? I don't want the image to lose any of its quality. You received this message because you are subscribed to the Google Groups "Android Developers" group.

General :: Playing Local Audio File In Webview App

Feb 3, 2012

When trying to play a local mp3 file included in the APK, nothing happens. However, if I pull an mp3 from the web it works.

e.g.

< a u d i o src="[URL]..." > WORKS

< a u d i o src="01.mp3" > DOES NOT WORK

I tried looking through logs for clues and found this line. I'm not sure if it's relevant or not.

PlayerDriver::isProtectedFile(file:///android_asset/www/01.mp3)

I'm new to Android development, so I can only guess that the file is somehow inaccessible for streaming.

I'd love to get this figured out though. Having to pull the files remotely every time is not a desirable solution.

Some additional info. Either solution works when tested in the browser. The local file problem only arises when I convert it to an app. I'm using PhoneGap build to create the APK.

Android :: WebView-based Browsers Accessing Protected Resources Through Oracle Access Manager -OAM

Oct 5, 2010

We have a website that makes use of OAM for single sign on (form-based authentication). When we submit credentials to WebGate / Access Server the authorization succeeds, however after the authentication is performed, the form action (as configured in the Authentication Scheme - with passthrough:no) returns a server error instead of redirecting to the originally requested URL.

If we use Mini Opera, we are able to get authenticated and forwarded properly.

This problem happens on numerous Android phones (versions ranging from 1.5-2.2), as well as the Emulator provided with the SDK.

This is proving to be a real problem as the default browser on Android phones is not able to get access to our sites(and this is the only browser that is having this problem).

I have created a WebView-based custom browser with the hope of seeing a client-side error and tried trapping every possible error....none show up....

I have tried to trace all of the http requests and found only a single difference in the requests... the http header for Connection:keep- alive is not sent by the Android WebView.

I have provided some tracing info below...

CODE:....................

Android :: Clarity On Wi-Fi Based Application

Jul 30, 2010

I am trying to create an application based on Wi-Fi and i would need some suggestion on the same , The scenario am trying is,say, when a user with our android application enters a specific Wi-fi Hotspot, i need an activity to be invoked from my app. Basically I can have a service running as a part of my app and whenever i scan for that specific hot-spot i can call up the activity , BUT , i need to do the otherway round.. i mean instead of running a service in the mobile and utilizing its resource, i want the Wi-fi Hotspot to monitor and if the device is inside the vicinity it needs to invoke a notification from which the activity can be invoked... Few things that i would like to understand is I) When a wifi hot-spot is detected in our android phone what actually happens at the Wi-Fi Hot spot end ?? 2) When our device obtains an IP address from the wi-fi n/w will our device's unique ID or its equivalents be available at the wi-fi provider end ?

Android :: Distributing Service-based Application On Market

Nov 22, 2010

We going to develop commercial application that will run on Android platform and now I'm thinking about distribution model.

Application itself will be of no use to regular Android user and will be installed only by people who know why they need it. Application will authenticate with server prior to launch.

We as a company will charge application users monthly fee and will track usage, etc via our servers.

So, I was wondering if there "locked" portion of market for this kind of stuff? Or, do I release app as a free one and if random people download it - they just won't be able to use it?

What is the best way to do that? Can I install application by giving users our URL?

I'm trying to make it as easy as possible.
