Android :: Database Connection Java File - Check Data - Login Page

Jul 8, 2010

I'm doing Major Project on my final year and I'm very new to Android plus I;m not good at codings. I need help with my login page.

I've created something like a database connection java file which is this:

CODE:.......

I've already created a database for users using SQLite. The database name is Users and the table is called User. The records inside the table are Username, Password, LastName, FirstName. I've inserted one user's info into the database. The problem is I do not know whether my UserDB.java is correct.

And I've also created login.java. Hardcoded Login page:

CODE:.........

So I want to know how I should apply the database connection on the login.java. Should I insert database connection something like db.Open();? I studied ASP.Net a few months back and I kind of forget most of what I've learnt. So how should I open the database connection on login.java and how to check with database whether the user enters the right username and password?

Android :: Login Page - Database Connection And Checking Of Username And Password. Edit Text Set To Dots?

Jul 8, 2010

I've modified my previous code for login.

CODE:.......

As you can see, I've left a blank on my if..else. I do not know how to apply an sql statement to check the user and password.

CODE:....

I've insert onClick(); to direct to the other method so that the user will be directed to another page by using the onClickListener method, intent. But I'm having trouble doing that and so I thought that my code is wrong or there should be another way to direct to the other page once the user entered the correct username and password.

Before that, what should I do so that there would be a database connection? Or have I created a connection by inserting db.Open()?

I need to know the codes needed to be inserted the if..else statement.

Another basic stuff I want to know is how to set the text on the password edittext box to dots instead of the actual text.

Android :: Login Page - Match Username And Password From Database To Allow User To Login

Jul 1, 2010

I managed to create the logic for the function but I have no idea how to match it with the database. I only know how to do it the hardcoding way.

Below is how I did it. I believe an sql statement should be inserted there am I right? And I know I missed out something. Before I match the username and password, I should check whether the user exist in the database first, and then check whether the password match with the username.

So in conclusion I need help on the 'if else' statement.

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

Android : ContentProvider Storage/memory - Data Can Be Stored In File System - In An SQLite Database

Oct 20, 2010

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?

Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

Android :: What Java XML Parser To Extract Data From 2000 Lines File?

Oct 5, 2010

In my Android app I need to extract data from a xml file (the file will have less than 2000 lines). I have no experience with XML parsing, so I don't know what the best approach is. DOM parser is perhaps not a good option, because I am on a mobile device. On the other hand with SAX I would probably end with more complicated code. What would you recommend?

Is there any class generators to process web services in Android/Java? I may have to write my own to generate classes against WSDL but I'm trying not to. Also is there one for REST services as well?

Android : Unable To Login - Load Any Page - While Using PDAnet

Jul 1, 2010

I installed PDAnet, it's been working fine until today. I logged on to my facebook & was playing games & messing around. Later I got online again, went to facebook, the page loaded fine. I typed my login info in, hit enter,it took a minute to load, then said page cannot be displayed,then a box popped up in the corner at the bottom telling me Secured pages are blocked, register for full version. So now I cant login to ANYTHING (except this website for some reason). Any idea as to why it was working fine before but not now?

Android :: Connecting To A Wireless Network Which Redirects To A Login Page

Jul 13, 2010

I need to connect to an institutional wireless network whose only security is achieved thanks to a login webpage. Once I'm connected to the wireless network, the first thing that I can do is to go to the login webpage. The problem is that most applications do not support this kind of login procedure, and therefore find no internet access (`connection problem' is written on my screen when I want to use the wireless network for surfing). Is there a workaround to this.

General :: Android Fails To Load WiFi Access Login Page

Aug 20, 2010

When I try to connect to my University's network , the my Galaxy S is able to connect JUST fine. However, when I open a browser it says the incoming certificate is not secure and then I have NO INTERNET on any page. It tries to redirect me to the login page for the network but fails to do so with a "communications error" and subsequent no internet access of any sort.

What the network is supposed to do is redirect me to the login page so that I can register the device to the network and login using my university account. My phone can't do that apparently and just sits connected to the network with NO INTERNET connectivity.

This is the university network and the instructions how to get on it for Android devices: [URL] .... I connect to it just fine but am UNABLE to get to that device registration/login page.

This is NOT just for my university. ANY public network which requires me to accept an "agreement" before it lets me have internet access, my phone KILLS ITSELF and CANNOT pull up the agreement page but instead tells me there is no internet. I'm SURE its a software problem or something with settings but can't figure out just what it is.

Just about the only networks I can connect to on Wi-Fi are home networks.

Android :: Check USB Connection Status?

Nov 6, 2010

I was wondering if would be possible to perform an action for each time the USB status of the device changes.

For example if the user plugs in the cable and it is in sync/charge mode it performs a certain action, if the user then changes the phone into USB Memory Card mode another action is performed and if the user then disconnects the cable then the another action is done.
