Android :: Saving Application State?
Jan 11, 2010I understand how to save an application's state by using SharedPreferences, onSavedInstanceState() & onRestoreInstanceState(), etc as outlined in a similar post ( http://stackoverflow.com/questions/151777/how-do-i-save-an-android-applications-state ), but how do I save the last activity?
To be more specific, my application starts up and goes to a login screen. Once a user logs in and navigates through several activities, lets say he or she leaves the app using the home button or in some other way. Next time the user starts the app, it will go back to the login screen and do a login again. Instead, I want the app to start up and go to the last activity that was on top of the stack when the user left the app in the previous session.
How is the last activity saved so that it can be restored on app startup?

Android :: Save State In My Application
Jul 16, 2010I am developing an android application in which,the first activity is that for Login. After successful authentication, user can see an activity with 4 Tabs. My problem is that when user taps on the home button,the application should terminate and when the user again starts my application, he should be able to see the Login screen again and after successful Login, user should be able to see the tab on which he was working before application terminated(i.e., save state for all the tabs).

Aug 9, 2010I've encountered a problem wile using my own subclass of android.app.Application. I have numerous activities in my application and I'm running a custom ROM which consumes quite a lot of memory. What happens is when I launch a third party activity (Camera) my Application is killed. My Application subclass stores vital data for the whole app so it can't work without it. android.app.Application doesn't have any methods for saving or restoring application state. Activity does have them but they are not suitable.
How to perform save/restore state on Application subclass?
UPDATE I've managed to do so by filling a Bundle obtained from onSaveInstanceState and restoring values in onCreate. But is there any better way?

Jan 11, 2010As a follow on from my question on sharing state between Activities, how can I save the instance state of my Application? Since Application does not extend Activity, there is no onSaveInstanceState method to override.
NB: In advance, this is not a duplicate. Despite its name, How do I save an Android application's state? relates to Activity state

View 5 Replies View RelatedAndroid :: Save - Complex - Application State To Bundle
Apr 30, 2010This is a bit complicated to explain (and my first post), so bear with me please: I am currently trying to figure out the best way of saving my application's state in a bundle on the onSaveInstanceState event (working on a game). My application's state is based on a "world" class which contains various objects. Among these objects there is a creature object which contains bitmaps (Bitmap object)(allowing me to draw the various sprites of the creature when it's walking with more flexibility and accessibility).
Bit of creature constructor Java:
CODE:.................
After looking around for a few hours I found that serializing the world object (and all its sub-objects) was an acceptable way of saving it in the bundle. Unfortunately it appears that we can't serialize bitmaps and considering they're a part of my "creature" I can't seem to see a workaround.
Here come my questions: 1- Am I doing something fundamentally wrong? (not supposed to save bitmaps in objects? supposed to handle bitmaps in a separate class which I don't pass on the bundle and reload my bitmaps when restoring the application? ...) 2- Is there another way of passing my "world" object into my bundle (would using Parcelable work?)
Android :: Stopping And Starting Service Based On Application State
Oct 28, 2010I have a Service which tracks the location of the user. Currently, the Service boots when the application starts and stops when the application terminates. Unfortunately, if users keep the application in the background, the Service never stops and drains battery.
I would like the Service to stop when my application is not in the foreground. I was hoping the Application class would let me Override onPause and onResume handlers, but it does not have them.
Android :: Reregister Phone State Listener If Application Crashed
Nov 17, 2009i've registered a PhoneStateListener in BOOT_COMPLETED receiver by using following call: tm.listen(new TestCallStateListener(), PhoneStateListener. LISTEN_ CALL _STATE); If the application crashes then system automatically unregisters the PhoneStateListener. Is there any mechanism of checking if particular PhoneStateLister is registered or not? Actually i'm thinking of starting a repeating service by AlarmManager which will check if PhoneStateListener is registered or not . And if it's not registered then service will register it again. Just a backup if application crashes. Is this a good approach or there is some better mechanism to make sure that PhoneStateListener is always registered even if application crashes ?

View 3 Replies View RelatedAndroid :: Changing Displayed State Of Views Based On Parent ViewGroup's State
Aug 11, 2010I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?

Android :: Save State Of Droid Application When Back Button Is Pressed?
Sep 20, 2010I have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.
View 1 Replies View RelatedAndroid :: Phone State Listener State Transitions
Feb 8, 2009I'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?

View 1 Replies View RelatedAndroid :: Is There Way To Automatically Update Application?
Jun 16, 2010I'm developing an application that will most likely be preinstalled on devices. It will be also available on Market. Is there a way to update those instances that are not downloaded through Market, since Market won't notify users about an update. I was thinking about, as suggested here, trying to contact my site periodically, and when update is available, download it. I'm wondering if there is a way to do this update automatically, so that user doesn't have to do anything (like running the package manually). Or, when my site shows update is available, to offer users an update through Market, even though it's not installed through Market. EDIT: This Market option would be preferable, because than users wouldn't have to check "allow install of non-Market sources".

View 2 Replies View RelatedAndroid :: Update Application From Market
May 5, 2009After different testing, I found an issue with the "update method" when installing an application update.
I developped "DilbertDroid", and a lot of people are saying that there is missing some functionnality but the latest version published on the market have this functionnalities.
I suppose that when updating a application, the updater doesn't kill the process related to the application but only update the application files on phone. Result: the old application is still running until you kill the process or reboot the system.
I think it is not very professionnal to tell user to deinstall and then reboot their phone in order to install an update.
My application doesn't have any service running

However when I updated the app through the Android market, my users experienced crashes.Since there is no way to properly debug this procedure I asume the crash is caused by old data which is not being removed from the device (probably from the onsavedstate bundle?!).Is there a way to do a "clean/total" reinstall without having the user to do it manually?
