Android :: DWR And Accessing Application From Browser
Aug 13, 2009
I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine.
So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening.

I have seen few apps having exact same UI when you access the app through stand alone app or through their mobile website. What are the pros and cons of both approaches while developing the app?

Is it possible to programmatically access the website that is currently displayed within the Android browser?
As far as I know the native Browser doesn't handle plugins (please correct me if I'm wrong), so I thought that reading the browser cache would be an option. Is there a more sophisticated way to get the currently displayed HTML?

My understanding says that it is yet not possible with Froyo to access native resources like Camera, Voice etc from Browser. Is that correct ?

I want to build an application that is able to read .CSV files. These .CSV files are downloaded NOT from within the application but just the regular Android browser. Now, when I start my custom application, is that download available to me? Any examples?

I'm building an Android application that needs to communicate with a MySQL database. The application isn't meant to be published, and I want the application to be the only thing allowed to interface with the web service I'll create for DB access.
I've been thinking how I can secure the system, and this is the idea I've come up with. I'd appreciate any feedback or other ideas. Surely there is a method built into Android that I am unaware of.
My thought is to give the web service a GUID. Each time a call is made to one of it's public methods, the web service matches its GUID with the GUID given to it by the Android application. If the GUIDs do not match, the web service refuses access. In short, my system has a 128-bit password.

I am new to Android development and am interested in working out a design of an application. I am however, unfamiliar with the best way to handle what I want to do. I am interested in obtaining information from my band's Joomla website and placing it into an Android application. At the moment I'd like to get News articles posted and potentially other information that I create on the site. I was thinking of doing this by setting up RSS feeds for the website. Would it be better to somehow access the data directly by connecting to the database? I don't know PHP so I can't develop a webservice to access the content. Any ideas?

I have a todo list type application that stores all of the note data in a sqlite3 database. Each activity in the application needs access to the database to edit different parts of the data in real time.
Currently, I have each activity open its own DBManager object (the helper class I created to manage the database). This is causing problems though and I would like a slightly more global access solution so I don't have to keep opening/closing/creating a database.
I'm considering several options, and would like to hear pros and cons of each as well as other suggestions.
Singleton style. Have a wrapper class that returns a reference to the only database manager so any activity that needs it can use it.
Static Manager. Have the manager class be entirely static members and have it open the database on load. Easily accessible by anyone that needs it (which is everyone).
Merger between 1 and 2. I could make a database manager class that initializes the member singleton instance of the database and all of the data manipulation methods were static. Then I wouldn't even need a reference to the singleton to access the database.

So there's the app Chrome to Phone which I've been using to shoot urn's to my phone. Works great. But what about Phone to Chrome? Is there any apps that would send a URL back to your browser? I think that would be pretty neat. I often read things on my phone that I'd like to finish on my computer. I just email or spring pad them for now.

Using G1, go to http://www.myspace.com. Notice the site is able to detect the user agent from the browser and provides a link to search the MySpace application on the Android Marketplace. Google's http://code.google.com/android/devel/sign-publish.html# publishing provides options to search, e.g. http://market.android.com/search?q=pname:<package>. This does not work for me.

Here's what I'm attempting to do. I have a menu and when a user selects a particular option in the menu I want the browser application to open and display the web page. However, I cannot seem to do this. My application uses a TabWidget to display its content (which works perefectly) but I cannot for the life of me figure out how to open a link into the browser. I have tried adding a WebView to the TabWidget (but when I request it from the view by findViewById(...) I get a null.
I've also tried creating a separate view and performing a setContentView(...) and then I get an exception. I've also tried using an intent I've seen demonstrated on this group. It seems like this should be fairly easy, but I must be missing anything. I've looked at the sample apps as well as the Apps-for- android samples and have followed them to the T, yet still to no avail I cannot get the browser to open (or anything like that).

I downloaded opera mini and have it and the stock browser on my phone. When I got it, it asked what I wanted to use as default for internet. Well my bookmarks mainly and I chose the stock. Now, I'm in Nigeria and the internet isn't great on my phone, but I'm getting a 100Mb allowance today. I want to revert to Opera as my default cause it uses less Mb and I am here for a month so want to stay within my quota. Is there any way to do this?

I have found that on lots of occasions the app or browser I am using switched to "landscape" mode without me meaning to do so. Is this because my phone isn't calibrated right? And when it does, it often doesn't switch back to the portrait mode even if I shake it upright - I have to exit the app/browser back to Home screen (which is always portrait) and then re-enter the app/browser and it shows up the correct way.

Has anyone experienced the sudden exit from an application or browser? It happens intermittantly on my phone where it will suddenly exit out with a vibration or two and return to main page. This has happened infrequently but many times in the past couple weeks.

Is there a way (possibly using javaScript) to define an HTML button that will, once clicked, to open the Android Market application (the one with greenish icon)? For such a feature to work right we'll need, of course, a way to determine whether the client browser is running on Android.

I'm using the blow code to open the gallery and grab an image for an incon im gong to store in a database and access later to populate a listview attached to a simpleCursorAdapter...........
The code runs, and then starts force closing (what seems like) randomly. I'm convinced that I've gotten something confused somewhere but since the force closure happens at all different points of my app I dont know where to start looking.
