Dec 30, 2009I am developing an application in which the user require to register first and than got the user page. For that i have made layout and the layout consist many fields, so, i have made part of layout and also made the separate activity for the each layout. The layout like address, phone, etc... After that i have wrote the code for calling an activity and it works fine. It means when i press the "Next" button the another page will come and it will also consist some textview ,edittext and previous and next button. Actually, i want something different like -- When the user fill the first form and he will proceed to next, the content written by the user should not gone when the user press "Next" button. The content should be there which was written by user. And same way i have have 6 pages like that way to complete the registration process. So, have you any idea to solve above problem? I really need your help because right now i stuck at this point. So, please any body help me out of this problem. I would appreciate your help. I am waiting for your reply.

Jul 24, 2009This is an intermittent bug in one of my apps. I don't expect anyone to solve it immediately, but I'd appreciate any thoughts on how to start debugging!So, my app lets users edit an item (in the EditPage activity). When they press the Back key, the desired behaviour is that it saves their edits and returns them to the home page (the HomeList activity). The code for this is below. It works fine. Except.The bug is this. Some users report that sometimes when they reopen the application after a pause, they are seeing *not* the home page, where they left the application - but the previous edit activity. Crucially, they are also seeing the edit activity without their saved edits - effectively losing their most recent edits.I've been able to reproduce this myself. It only happens after the application hasn't been opened for a while. If I save something, minimize the application and reopen it straight away, it shows the HomeList activity just fine, and the edits have all been saved. But if I save something, leave it for a couple of hours and then reopen it, it shows the previous EditPage activity, without the saved edits (i.e. in the state that the EditPage activity was previously launched).
Any ideas, anyone? I had wondered whether it was due to the Back button being used to return the user to the HomeList activity - maybe Android thinks that the Back button means that the HomeList is not the most "recent" activity, instead the EditPage is. I'd like to carry on using the Back button if possible, though. And in particular, I'm puzzled why it only happens after the app has been idle for an hour or so, and not immediately? Is it something to do with Android's memory management?
Android :: Previous App Launches Not Starting Activity

View 4 Replies View RelatedAndroid :: Back Button Doesn't Go To Previous Activity
Jul 4, 2010I have two activities. The first is a list where the user selects one of the items which takes them to a second activity showing the details of the item they selected. When the user clicks the back button I want the app to return to the first activity.
Is there anything special i need to do to make this happen?
Right now when I click the back button from the second activity it exits the app just like the home button would.
Here is how I am starting the Second Activity. startActivity(new Intent(getApplication(), SecondActivity.class)); finish();
Android :: How To Tell A Thread From A Previous Instance Of Your Activity Has Finished
Oct 31, 2010I'm writing a bitmap editor and I'm trying to write an autosave feature. When onPause is called, I write the application state to an autosave file. As this takes between 0.1s and 1.5s, I've been advised this IO operation be performed in a background thread.
In the onCreate method of my activity, I check to see if the autosave file exists and, if it does, I open it.
Are there any scenarios I have to consider where the user can somehow leave the activity, the autosave thread starts and the user can return to the activity before the thread has finished? If so, how can I detect this and wait for the thread to finish before I check the state of the autosave file?
I was going to make it that, when the user backs out of my activity, they're asked to wait a second while the data is saved. This seems OK, but I can't do this when my activity is interrupted by something like a phone call.
Also, I'm a bit confused about how multiple versions of the same activity can be started as this makes dealing with autosaving more complex. Is there a way to make sure only one instance of my activity is allowed to run at a time?

View 1 Replies View RelatedAndroid :: Previous Set Instance Variables Null When Activity Resumed
Apr 20, 2010I am using an Application object to store app-wide instance data--data that I need to remain in existence for the entire lifetime of the app, so the Application class seems like the proper place to put it. I have just finished reading this thread http://groups.google.com/group/android-developers/browse_thread/threa... that goes into pretty good detail and receives confirmation from Googler hackbod as to how the Application class performs--and from that info it seems this strange behavior I am receiving should not be happening...
Basically, every once in a while when I resume my app in any of its Activities (it is still running in memory so onCreate is not called) I get NullPointerExceptions because instance variables in my Application class are returning null when I request them from my Activity (via a getter method in my custom Application class). It seems as if sometimes Android saves the states of my Activities but deletes all my instance variable data... This can't be an Android problem--there must be something wrong with my code.
Has anyone else ever ran into an issue of this kind? Any ideas as to what may be causing this? I'm not going to post my code here as that won't help anyone, but hopefully someone can point me in some helpful directions.
Android :: How To Start Application In Last Viewed Activity In Previous Session
Apr 21, 2010I'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?

Android :: Don't Need Previous Activities Load On Pressing Back Button On First Activity
Jul 15, 2010When i leave my app after pressing home button and then re launch it from menus it behaves in a strange way.Sometimes it launches the same activity on which i pressed home button.But sometimes it launches the first activity of my app. One reason for this could be that whenever system has memory shortage it clears any activities existing in But the strange thing is if i press back button from first activity it takes me back to the same activity on which i pressed home button and all other previous activities are also there(like if i press back button again previous activities also exist.)I haven't set any launching mode for any activity in my app(like single instance etc).What i don't need is that previous activities load on pressing back button on first activity.
View 2 Replies View RelatedAndroid :: Return To Previous Activity Without Calling Finish() / Save This Information?
Oct 26, 2009I have an android application with a LOT of activities, think of something like a book where every page is a new activity. The user can make changes in each activity, for example highlight certain texts with different colored markers etc. and it's crucial that I'll remember this information as long as the application stays alive (and I don't want/need to remember any of this when it's not). As I understand the best mechanism for storing this kind of information is via onSaveInstanceState(Bundle outState) and onCreate(Bundle)/onRestoreInstanceState(Bundle) rather than lets say, the Preferences mechanism. My only problem is that the user can navigate backwards to previous pages (Activities) and the only way i know of achieving this is by calling finish() which of course kills the current activity without calling onSaveInstanceState(Bundle outState) and even if it did call it, the next time I would launch an activity representing that page it would be an entirely new instance. So my question is: Is there a way to go back to the previous activity without calling finish()? or, is there a better way to save this information? maybe through static variables?

Activity Vars NULL After In-app Play Store Transaction?
May 31, 2012I've managed to incorporate in-app billing into our product but it is failing on one of my two test devices - a Samsung Vibrant / Galaxy S running Android 4.0.3
The transactions themselves are confirming - reserved product ID's and our actual product ID's - but on this particular phone once the response code is received and the app's activity is brought back into view, several variables holding operation-critical values are NULLed out, crashing the app and preventing actions associated with the purchase.
This DOES NOT happen on another test device - an HTC Sense running Android 2.3.4.
Both devices are running Play Store version 3.5.19.
At a loss right now for trouble shooting. If there is a way to extract the product ID from the signedData bundle returned from the Play Store it would be a way for me to side-step the problem.

Nov 21, 2010Ok, there is literally no way that I'm the only one who has asked this question but I can't find the answer by searching. Here's my problem, after I flash my rom and restart my phone the market begins auto-downloading all the apps I previously had installed. I do not want this bc I use titanium backup for all of that.
I know I can avoid it temporarily if I skip entering my email address, but there has to be a setting for me to un check that will make it not try to auto download anything once I do add my account.
I'm sure you guys have all run into this by now, so can someone please tell me what setting will resolve this issue?
