Android :: How To Keep The Session Of User Login
Apr 9, 2010
I have an app that requires user to register. I've got the app conected to PHP in my server to do the logic of register/login and so, this is not problem at all.
But, I want to keep a session of the user in local, so the user doesn't have to login again every time he runs the app.
So, I want something like this:
First time user, he opens the app, register and login. Do some stuff with the app and closes it. Open the app again, the user is recognized so he doesn't need to login again.
I only need to store an ID and a Username (both fetched from the DB in the login php method). What's the best way to do this?
I've thought about doing a custom preference, store the data in files or even a local DB (sqlite).

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.

I call WebView.clearHistory(), but I am still able to go back after doing so. I want to reuse a WebView, but I don't want the back button to allow the user to go back further than the current "session" of using the WebView. Anybody know what is the best way to handle this? I thought for sure that clearHistory() would do it.

I'm curious as to whether anyone else is having this problem or if it's just me. I just updated to the latest Tapatalk 1.8.0 and find I can't login to the forum I use it with (no, not this one). When I enter my user name and password it just bounces back to the login screen with no complaint.

I've downloaded a few networking apps (games) that have you log in, then take you to a "home" type screen where you can change your settings, or start a new game, or view your buddies etc.My question is two-part:
1) how are these "multipanel" apps created? Is each panel its own activity? I've tried adding different panels through Views, but on the apps I described above, when I hit the back button on my phone, it takes me to the previous screen and in my apps, it just takes me out of the app when I hit back (again I'll I've done are add separate views). Can someone point me in the right direction of what I need to do to create a multipanel application that when I click a button, a new panel loads, then when I hit back on the phone, it takes me to the previous panel?
2) one of my panels will be a login page which I will post the log-in credentials via http post to my server for authentication. I would like to remember the log-in "token" that is passed back to the client so they don't have to log in every time they use my application. Again, referring to some of the apps that I have, they offer this feature but I can not locate anything on the phone where it would be saved. Is this done with xml usually?

This is a follow up question of http://stackoverflow.com/questions/3550593/sending-html-commands-over-httpclient-android , I have successfully Posted to the server and received 200 code but when I attempt to move to another page it does not recognize that I have logged in. I am wondering if it is a session issue or if i need to follow the redirect after the POST. How would I go about following a redirect?

The user must login through the WebView. Of course, the session is for that WebView.But, what if I need to make REST API calls during my Android application?Those REST API calls need the session to be authenticated , otherwise those will not work. Is there any way I can attach the cookies of WebView into everything I do in Android?

I've got a problem with my application when I make a number of requests using the HttpsUrlConnection class.
My program makes the first request using the HttpsUrlConnection class to retrieve a file. It then makes a second request to the same server to retrieve a different file. What happens however is that periodically I'm getting a -1 HTTP response code on the connection.
When the failure occurs between the two requests I see the following line of trace in logcat:
D/OpenSSLSessionImpl( 699): Freeing OpenSSL session
This seems to happen fairly consistently. If I retry the second request after it has failed it generally works and I get the requested file from the server.
Note that if I don't see the OpenSSL session being freed the second request works fine the first time.
Some other information:
1) I'm not calling disconnect on the connection
2) I'm don't always read the entire file from the server after the first request
3) I always close the InputStream in the event that I get an InputStream on the first connection
How to prevent the OpenSSL session from being freed.

I'm trying to avoid that when a user has connected to Facebook from my webview, the next time he do it, doesn't need to put the email and password. but doesn't work. That cookie I suppose that is not valid because the user has to put his username and his password again and after login, I get a different cookie that the one I had stored. What I'm doing wrong? Is there another way to accomplish that?

Ok I am at the end of my rope. I am doing some image processing. I have a large image file which I open and create a smaller bitmap from. At the end of processing I call recycle on everything. I null everything. I run GC manually.
I then try edit another image and I get an out of VM memory error. Bitmap exceeds etc etc.
I am looking at the heap and the secone edit doesn't seem to cause it to increase at all.
What else can I do. Surely google cannot possibly be suggesting that we can open one large bitmap per session and thats it?

I am using Ksoap2-Android for consuming the WCF Services.
For the dotnet client we keep the allowCookies="true" in our binding configuration and it sends the same sessionid and keeps my sessions intact in my WCF services (My services are
interdependent and use the sessions).
Any one know any such setting for ksoap2-android, that will allow me to consume the
WCF service keeping my session intact on the server.
Currently when i make a new call to the service, the sessionid gets changed and all my
session variables clear out and loose their values.

For example, I want my users to be able to click a button "Get new quote" which will start a new row in the the database for data to start being stored, but I'm unsure of how to store activity independent (or cross activity) data, like the _id of the row, which I will need to requery and update the row when new data becomes available on subsequent activities. What's the name of this mechanism and how is it done?

I'm developing an app using android 2.1. I have a problem with using session cookies to login to a RESTful web service. The code works fine on the emulator, but when I run it on my HTC Magic, the cookie logic doesn't work. I've confirmed that the magic is receiving cookies in the headers by listing them (see attached). Can anyone say why the cookie store would be empty even tho they are in the headers?

I'm writing an application consisting of several activities and, on restarts, I'd like the application to initially display the application's activity that was the last to display in the application's previous session.
I save information about the last activity in SharedPreferences and I'm trying to start that last activity with a call to startActivity(intent) from my Application's onCreate handler.
The problem is that if I don't set the intent's FLAG_ACTIVITY_NEW_TASK, the result is a run-time exception message in logcat suggesting that I should set the flag. And if I set that intent flag, the correct activity gets started but doesn't fully initialize resulting in null pointer exceptions (which don't occur when I don't attempt to start the activity from my Application class).
CODE:...........
Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
How to correctly start a particular activity from the Application class's onCreate handler?

We're designing an Android app that has several activities which are working in a wizard like way - user should pass from the activity #1 to activity #5 to get to the final activity (#6).
Since we know an activity can be suddenly terminated by OS on low memory we used Application class as a static storage for keeping the data the user inputs on "wizard" activities and other data our app needs for the whole session.
Unfortunately we've discovered this approach fails - looks like the Application class instance is also can be killed by OS (this was specifically discovered on Android 1.6 versus 1.5). Are our expectations wrong on this approach (we think Application class instance always lives for the whole app session)?
So the question is - what is the best practices on Android to keep data between activities deathes/restarts for the whole application session?

I just ran through the Unrevoked process, which ended in the software telling me, "This was a triumph". I am, however, unconvinced.I can not boot into any other recovery than the stock HTC recovery and therefore can not perform a Nand Back up or flash Unrevoked Forever.I'm running a newer Evo with 2.2, it has hboot 2.02 and is showing S-ON. Is this the problem?

I have an Android application which connects to my desktop via SSH when I load it, it works fine. When I click a button on the interface on my phone, it sends a command through the SSH connection to be executed on my desktop, that works fine also. The problem is I have one class that opens the connection and sends all the commands through. I call this class from my onCreate method with button listeners.
So I have my class Init which opens the connection when the program starts, then I have a button listener for button_1 which calls
Code:
Init.send("mkdir "test_directory");
No problem, that works great but what if I want to have a button on another screen? How can I get the same Init object to maintain the open session with my desktop? If I create a new Init object in the other class it will reconnect on a new session but I want to use the same one.
So I'm wondering how I can (for example):
1. launch application, create Init object and call Init.connect(username, password, port, host)
2. click a button and use button listener to call Init.send("mkdir test_directory")
3. click a button and load a new screen with new buttons
4. this loads a new .java class with a new onCreate method to manage the new display with new buttons (is this necessary?)
------------everything works up to here--------------
5. click one of the new buttons managed by the new class but use the same session created in the original class from the original Android screen
To explain exactly what I'm doing, screen 1 has a button which loads screen 2. Screen 2 has a list of directories on the remote machine. Screen 3 has a list of directories inside the directory clicked on screen 2. I want to send a request for the directories on screen 2 using the Init object created from screen 1 which was displayed on launch.

Getting this in their notification tray? This has been happening once I turn my data back on after it being off to save battery. It also asks for you to log back in. Sounds like someone phishing so they can hack my accounts.
